Complete LVS verification methodology and process for complex System-In-Package assemblies

Raphael Theveniau
CAD Support Senior Staff Engineer
ST Microelectronics

Abstract
Systems in Package (SiP) have been around for some years and were typically the integration of multiple bare unpackaged chips along with discrete devices interconnected with just a few signals. However, as silicon scaling (aka Moore’s Law) slows and silicon densities reach their physical limits, there is growing shift to disaggregation of once monolithic functions into smaller, node optimized high yield chiplets, heterogeneously integrated on a high-performance substrate as an advanced System-In-Package (SiP), or module. These designs utilize multiple high performance and high bandwidth interfaces between the chiplets enabling higher densities, greater device functionality, and improved overall silicon yield. All the devices used in a SiP are often designed concurrently, by different teams, in different time zones. Thus, the risk to make mistakes in data exchange is very high. To mitigate this risk a comprehensive system description along with a controlled data exchange flow is key. Furthermore, although each device is tested independently, there is a need for a formal signoff check or verification that covers the whole system.In STMicroelectronics we have developed an automated layout versus schematic (LVS) methodology that electrically verifies the module and system-level designs logical connectivity. Using a combined 3D assembly level DRC/LVS methodology our divisions can prevent System in Package failures due to swapped balls, shorted power nets or any uncontrolled change in the design layouts.This paper will describe the essential steps and process of a fully integrated workflow that can verify and validate a complete multi-chiplet SiP design assembly using an LVS approach including the technologies used to enable such a solution.

Ultra-fine pitch Die bonding approaches with Cu interconnects for high-performance 3D IC packages

Ali Roshanghias
staff scientist
Silicon Austria Labs GmbH

Abstract
Cu to Cu direct bonding is currently the most attractive approach for 3D integration due to its compatibility with the wafer back-end-of-the-line (BEOL) fabrication process. Direct or hybrid Cu bonding is an established wafer-to-wafer (w2w) bonding process at foundries. However, considering the increasing demand for heterogeneous chip stacking and high production yield with known good die (KGD), chip-to-chip (C2C), and chip-to wafer (C2W) Cu bonding processes still encounter technological challenges. In this study, we will explore different die-level bonding strategies for both protruded and recessed Cu interconnects. Here, Cu bumps with a diameter of 4 µm, and a pitch size of 18 µm surrounded by SiO2 layer were fabricated with different topographies (dishing heights) and were bonded at the different bonding temperatures. The results of the electrical examinations, bonding strength, texture, and interface analysis will be further discussed here.

Optimization of the Cu Microstructure to Improve Cu-to-Cu Direct Bonding for 3D Integration

Ralf Schmidt
R&D Manager Semiconductor
Atotech

Abstract
Advanced packaging solutions and heterogeneous integration are key technologies to enable devices with improved operating characteristics, including higher performance, increasing power efficiency, and decreasing form factor. Packages with high I/O densities are required to efficiently combine, e.g., processing and memory units but impose restrictions to the pitch of the interconnects. Conventional technologies, including wire bonds and flip chip bonds are limited to larger pitches and, therefore, not suitable to meet the requirements of upcoming packaging technologies with respect to I/O densities. Direct copper-to-copper interconnects are supposed to allow such small pitches of 10 µm or even below. However, formation of such bonds usually requires high temperatures and pressures. Temperature-sensitive devices like DRAM components restrict the maximum temperature that can be applied to the package. Thus, copper material is required, which allows bond formation at relatively low temperatures. In this context, hybrid bonding processes were discussed that involve initial bond formation via the usually oxide-based dielectric at room temperature followed by copper-to-copper bonding at elevated temperatures. The copper material is usually prepared by electrolytic deposition and the properties of the respective deposits may be modified by properly designed organic additives as well as process parameters. Strong bond formation of the copper should be obtained upon grain growth over the interface of the two deposits, which are brought into contact during the bonding step. In order to facilitate such growth at relatively low temperatures, suitable microstructures need to be prepared. Ideally, morphologies should be chosen in a way that they can be maintained throughout all process steps after the electrolytic deposition but, at the same time, allow grain growth over the interface during copper-to-copper bonding. Various strategies to enable improved seamless grain growth and maintain suitable microstructures throughout the preceding process steps will be compared in terms of the resulting copper microstructures after bonding. In this context, different electrolytic copper deposition processes, the resulting morphologies, as well as their respective advantages and challenges with regards to copper-to-copper bond formation will be discussed.

Predictive Maintenance Scheduling for Assembly Manufacturing

Christopher Bode
Technical Product Manager
INFICON

Abstract
The semiconductor industry and its struggles with supply chain issues have made the global news almost daily. Tactical options to address issues with existing manufacturing assets include getting more capacity out of existing fabs and/or enabling fabs run a broader mix of technologies and products for a longer period. Factory automation capabilities are certainly a necessary solution to facilitating such improvements, whether in terms of maximizing tool availability or manufacturing productivity. Assembly facilities are beginning to adopt such solution in volume from their front-end manufacturing counterparts to good effect. Smart Manufacturing solution integration is increasingly demonstrating the capability to move beyond point solution development in back-end facilities to deliver differentiating capabilities in manufacturing efficiency and productivity. This talk will discuss examples of harmonizing deployed solutions to facilitate predictive maintenance scheduling through the integration of tool control and factory scheduling.INFICON has deployed Smart Manufacturing capabilities to a customer Assembly site that demonstrates the end-to-end solution and business process integration of a predictive maintenance capability. FabGuard® Fault Detection and Classification (FDC) is deployed on a Disco grinder tool to monitor a number of tool parameters for general tool control capability, but also monitors the blade thickness over time to predict when a blade replacement will be needed. Such information is shared with the factory Digital Twin to support overall factory modeling and prediction capability. Factory Scheduler, in addition to performing the nominal responsibility of scheduling material to be run on each of the tools, can consume the FDC data and maintenance prediction to schedule an optimal time to perform the tool maintenance given operator and tool availability. The shared decision support with the integrated solution makes it so that the parts and assignment of duties can be done ahead of time, minimizing tool downtime and maximizing maintenance efficiency. The presentation will discuss the deployment and impact of these solutions as deployed in our customer facility.

Ultra low-temperature silver sintering materials for substrate-based power applications

Rui-Xuan Dong
Project Leader
Niching Industrial Corp.

Abstract
The demand of high powder semi-conductor devices is increasing continuously. Especially for wide band gap (WBG) semiconductors, the die-attach (DA) materials need to be bonded at a lower temperature,≦200 ^oC ideally, and operated at a high temperature (~300^oC). Low-temperature sintering silver provides excellent properties to meet the requirement of DA materials on WBG applications. The common sintering temperature of commercial products is > 200dC. High sintering temperature generates a higher level of thermal stress in the DA materials, which would cause negative effects for larger dies, including void generation, delamination, crack, metallization peeling, and so on. Lower sintering temperature could reduce thermal stress during packaging processes. In addition to 200-^oC sintering Ag paste (DN-1206Q), we have developed DA Ag paste with 175-^oC sintering temperature (DN-1301A) for the requirement of low stress. This article is investigating the effect of sintering temperature on the performance and properties of DA materials.The storage modulus of 175^oC (DN-1301A) and 200^oC (DN-1206Q) sintering Ag paste are 14 and 18 GPa respectively. This is more than 20% reduction which could be a great help in terms of thermal stress. As for die shear strength (DSS), DN-1301A showed comparable results while curing at 175 ^oC comparing with DN-1206Q curing at 200 ^oC. Thermal conductivity (TC) of both 175 and 200-^oC sintering Ag paste is more than 120 W/mk. In summary, lower sintering temperature can reduce the thermal stress of DA materials which is a positive contribution to the resistance of temperature variations. The performance of DN-1301A curing at 175 ^oC is similar to 200^oC sintering Ag paste (DN-1206Q). Based on this study, it is very promising that a lower sintering temperature at 175 ^oC for silver sintering paste can deliver similar performance as curing at 200 ^oC. This could be a breakthrough for those requiring lower curing temperature such as laminate substrate-based packages.

3M Insulative Thermal Bonding Film (ITBF) for Power Module Packaging

Walther Grommes
European Application Development
3M

Abstract
Abstract:The traditional substrate used in power modules is ceramic based, and typically called a Direct Bonded Copper (DBC) substrate. Comparing to DBC, the newly emerging Insulated Metal Substrate (IMS) shows benefits in smaller and thinner design with higher power density, better warpage control in packaging processes, and potential overall cost reduction, while offering comparable heat dissipation. The key insulation material in IMS is the organic composite thermally conductive sheet bonding to both copper foil and baseplate. The current challenges for this insulation material is how to improve its thermal conductivity, insulation properties, processability and long term reliability.In this presentation, we introduce a new 3M solution for Insulative Thermal Bonding Film (ITBF) for IMS substrate in power module packaging. Based on 3M thermal management material technologies for filler, polymer and processes, we have developed a thermal bonding film with thermal conductivity up to 12 W/mK, and with superior insulation breakdown voltage >6.5 KV at thicknesses of 120 and 150 μm. Material aging and shelf life studies have been conducted. 3M ITBF film showed stable performance in 3000-hour aging tests at 150^oC, showing 3M ITBF advantages in product handling and reliability. IMS substrates have been fabricated with 3M ITBF film and have demonstrated good copper bonding and lamination processability. Both thermal resistance and dielectric insulation have been measured based on industry standard methods, demonstrating that 3M ITBF film can enable high performance IMS. Based on the fabricated IMS substrate, a materials model was established. Simulations of heat dissipation and stress management demonstrated that 3M ITBF can significantly reduce insulator stress and slightly improve chip solder stress. Furthermore, the development of 3M ITBF roadmap is discussed.Walther Grommes, Patricia Tien, Monroe Wang, Davie Wang, Koji Ito, Evelyn Liao, Marc Dunham, Benson Chen, Wei Zou

Semiconductor Packaging Materials Enabling Advanced Flip-Chip and Heterogeneous Integration

Ramachandran Trichur
Global Head of Semiconductor Packaging
Henkel Corporation

Abstract
In recent years, semiconductor chip package architectures have become more complex to deliver various applications’ power, performance, size, and cost requirements. Chipsets used in consumer electronics devices such as mobile phones and handheld electronics predominantly require miniaturization, high functionality, low cost, and low power. Therefore, the packages specified for this market segment may include package-on-package (PoP) formats to save space or wafer-level packages (WLP) to deliver lower cost and, in many cases, higher functionality. In comparison, processors used in high-performance computing (HPC) and artificial intelligence (AI) applications place a premium on performance while balancing cost, power, and footprint. Because of these factors, packaging architects have developed several custom package formats like chiplets, large-die flip-chip, and multi-chip packages in 3D and 2.5D, among others. Both end markets require unique innovations in semiconductor packaging materials to enable efficient package production and in-application performance. While package designs have come a long way, challenges to meeting new, demanding requirements persist. Advanced packaging material solutions are central to addressing these issues.Liquid compression molding materials are predominantly used in fan-out or chip-on-wafer packaging for wafer-level encapsulation processes. As the interconnect density or stacking height increases, fine-filler, low-warpage materials are necessary to deliver the package's reliability and the wafer's processability. In AI and HPC applications, the package body size increases with subsequent generations. These large body packages are susceptible to thermal stresses resulting in warpage and reliability concerns. Component level adhesives like lid and stiffener attach materials must be able to manage/prevent warpage while maintaining good adhesion and reliability performance. Lastly, underfills also play a crucial role in packaging logic and memory devices. Pre-applied and post-applied underfill in liquid and film formats are needed to address challenges in flow time, interconnect density, voiding, crack formation, and various other issues. This Keynote will present the latest innovations in encapsulation materials used for fan-out wafer-level molding processes, alongside developments in advanced liquid underfills and lid/stiffener attach materials.

GlobalFoundries 22FDX^® Auto grade 1 Chip Package Interaction Reliability Assessment

Simone Capecchi
MTS Reliability
GlobalFoundries

Abstract
Semiconductor devices are becoming every year more pervasive in the automotive industry. Moreover, the growth of the Electrical Vehicle (EV) market in addition to new features such as Advanced Driver Assistance Systems (ADAS), Lidar and auto connectivity is accelerating this trend. The value of the market for automotive semiconductors applications is set to grow from about $35B in 2020 to about $80B in 2026 (~15% CAGR) and it is expected to reach about $300B by 2035*. Therefore, this tremendous growth has generated an increased interest for semiconductors IDMs and foundries to enter or strengthen their presence in the automotive supply chain.In this work we present a chip package interaction (CPI) Automotive Grade1 reliability assessment performed onto to a GlobalFoundries 22FDX^® technology test vehicle. The presentation will focus mainly on the temperature humidity bias life test (THB), which is one of the AEC-Q100 requirements. The aim of the CPI assessment is to prove that the GlobalFoundries 22FDX^® back-end of line metallization (BEoL) the passivation and the Far BEoL interconnects are robust enough in an Auto G1 standard package and can withstand the AEC-Q100 grade 1 reliability environmental stresses.For this purpose, a test vehicle has been designed and fabricated by GlobalFoundries Fab1 including the Cu pillar interconnects. The subsequent packaging has been carried out by an external Auto G1 qualified OSAT using their Auto G1 HVM bill of material (BOM) and assembly process. The environmental stresses and electrical readout have been carried out in GlobalFoundries Fab1.The test vehicle is a 22FDX^® 8x8 mm² silicon die assembled in a 14x14 mm² Flip Chip Chip Scale Package (FCCSP) with an Embedded Trace Substrate (ETS) coreless substrate. This test vehicle contains various kinds of CPI sensors distributed in sensitive die locations.Compared to the component level reliability stress, which is also carried out as part of the CPI assessment, the THB assessment requires a dedicated board level stress and a dedicated test infrastructure. The THB adapter card assembly process, the electrical test pre and post stress and the THB reliability environmental stress have been set up and carried in GlobalFoundries Fab1.The focus of this presentation is on the technical challenges, such as the CPI structure design, the THB board and adapter card design, the electrical readout, and the adapter card assembly.*Source: Yole Développement

Reliability Characterization of Silver Sintering for Die Attach Applications

Edsger Smits
Program Manager
CITC

Abstract
With advances in miniaturization of electronic components, there is a trend towards ever increasing power density in semiconductor devices. In part, Wide-Band Gap (WBG) materials such gallium nitride (GaN) and silicon carbide (SiC) have enabled more efficient devices but also allowed for much higher operating temperatures. Consequently power dissipation and mechanical stresses in electronic packages have increased dramatically. From environmental perspectives, there is a strong drive to phase out lead-based solder.Discrete components are commonly assembled in packages based copper lead frames. The key challenge for such packages are the mismatches in coefficient of thermal expansion (CTE) between Cu lead frame and WBG power dies. During operation, the packages repeatedly undergo temperature swings, causing repeated thermomechanical stresses and fatigue. When not mitigated, these stresses lead to premature failure of the electronic components.Silver Sinter pastes (pressure based and pressureless) are a promising replacement of lead rich solder combining superior thermal and electrical performances. It is the scope of major research activity but a reliable solution for attaching WBG semiconductors to copper bases while retaining superior thermal and electrical performances has proven to be challenging. Unlocking the full potential of WBG semiconductor power electronics will hinge on solving these technological challenges at the package level.In this presentation, the author presents an overview of CITC research activities on advanced packaging with a focus on packaging for power electronics and silver sintering solutions. An overview of the current state of silver sinter materials is provided. The performance and limitations of the materials are addressed. Beyond materials, methods used to investigate the performances and degradation will be covered as well as the thermomechanical simulations for predicting package reliability.
