Abstract
Sensors are found in a wide range of applications and industry sectors and the market is as a result in good health overall. While consumer sensors are adopted rapidly and wax and wane rather more quickly as markets, new sensing applications quickly emerge to keep MEMS sensor suppliers busy. While smartphones still represent a huge market, commoditization has left it saturated in value terms, but growth has recently moved to other accessories like smart watches or wireless earbuds from leading suppliers like Apple. Such devices are becoming very smart, involving multiple accelerometers and silicon microphones per set, and potential further functionality on the way in the form of heart rate, even oxygen saturation, and blood pressure. Talking of pressure, this sensor was recently adopted in e-cigarettes for puff detection. Other mainstays like automotive and industry, on the other hand, are subject to longer-term trends like electrification and robotization of the car, as well as Industry 4.0, big data and condition monitoring. Meanwhile, autonomous cars or taxis are not the only markets to watch: automation of many functions is taking place, e.g. in smart cities, smart building such as warehouses and logistics operations, in logistics and package tracking, in drones for surveying and mapping. Agriculture is also benefiting from sensors, drones are used for crop spraying, for example, and other sensors are used to monitor other key metrics like acidity, etc. Robotics and automation implies many sensing devices including position, motion and pressure sensors. This presentation looks at the impact of these major market changes on MEMS and other silicon sensors.

Thermal Treatments in MEMS Fabrication:Challenges and Benefits of Rapid Thermal Processing (RTP)

Juergen Niess
Director Technology
HQ-Dielectrics GmbH

Abstract
Thermal treatment in general, but also Rapid Thermal Processing (RTP) in particular, are well established processing technologies in semiconductor manufacturing [1] , [2]. Even though MEMS fabrication is using the same fundamental technologies and methods, there are new challenges coming up with new device layouts and structures.Whereas most advanced processing technology in semiconductor device fabrication is done and available for 300 mm wafers, the highest performance requirements in MEMS fabrication are needed for 150 mm and 200 mm wafer size. As a consequence, there is a lack of equipment, addressing the technology needs of MEMS device manufacturing on relevant wafer size.Furthermore thermal mass distribution on semiconductor device wafers is rather uniform along the wafer radius, whereas MEMS devices often exhibit areal distributions of etched trenches and holes, having a distinct influence on thermal mass and its distribution over the wafer. Especially during the non-equilibrium phase of a thermal treatment, these areal variations have a strong influence on heating rates, soak times, and maximum temperature over the wafer.Last but not least, specific materials combinations, e.g. for contact formation, with specific properties (durability in harsh media, at elevated temperature,…) are requested in MEMS device technology, which have to be characterized and understood in terms of reaction kinetics e.g. with silicon, in terms of deposition behavior, and last but no least in terms of thermal treatment.The present publication discusses the various influences and challenges, and introduces potential technologies addressing those challenges. Using the example of pressure sensors, the efficiency of used methods is discussed.

New technology for inhalers and sprays for a healthier world

Wietze Nijdam
Technology Manager
Medspray BV

Abstract
Medspray is inventor and manufacturer of innovative spray nozzles. Located at ‘Kennispark’, the business and science park of Twente University in the Netherlands, Medspray uses nano technology to create spray nozzles from silicon with tiny orifices (approximately 2 micrometer in diameter) for a fine nebulization. For reference, a human hair has a diameter of 70 microns.Medspray is ISO 13485 certified for development and manufacturing of medical devices. The production of spray nozzles is located at Medspray in Enschede, in dedicated ISO 7 clean rooms. World wide partners assemble Medspray’s nozzles in mutually developed spray devices. In the summer of 2019 Medspray expects to make its 1 millionth spray nozzle unit, in 2020 we expect to scale further to a production of more than 1 million nozzles per month.Medspray’s mission is based on sustainability. The use of propellants in spray cans for cosmetics and in inhalers can be completely avoided by using Medspray nozzles and simple mechanisms like a plastic pump. Current HFA pMDIs (pressurized metered dose inhalers for e.g. Asthma and COPD) have a similar CO2 exhaust as a car trip of 290 km!Since the inhaler devices have entered the public domain, our nozzles also have caught the attention of other industries, such as cosmetics. Ap apparently the requirements of a spray for the pharmaceutical industry also apply for the cosmetics industry: long actuation time (multiple seconds), narrow particle size distribution, tuneable spray cone and propellant free operation.Medspray, tiny technology for a sustainable future.

Cutting-edge Plasma Dicing for wafer singulation applied to MEMS devices

James Weber

Panasonic Industry Europe GmbH

Abstract
Authors: James Weber^*1, Atsushi Harikai^*2, Kiyoshi Arita^*2*1: Panasonic Industry Europe GmbHRobert-Koch-Straße 100, 85521 Ottobrunn, Germanyjames.weber@eu.panasonic.com*2: Panasonic Smart Factory Solutions Co., Ltd.2-7 Matsuba-cho, Kadoma-City, Osaka, 571-8502, JapanAbstract:MEMS market trends are demanding dies that are thinner, smaller, and stronger. Conventional line-by-line dicing methods, such as mechanical sawing (“blade dicing”) or laser dicing, are not suitable for fragile MEMS devices, both in terms of economics and reliability.Plasma Dicing is an alternative method to overcome the many challenges of MEMS wafer singulation that are encountered during conventional line-by-line dicing methods.Plasma Dicing for MEMS wafers utilizes plasma trench etch (“dry etch”) technology and is damage-free (no chipping, no cracking), offers smoother sidewalls, is particle-free and enables high-throughput. In addition, flexible chip shape design—including round and offset chips is possible.Plasma Dicing is performed by opening dicing streets on a mask on the wafer surface, and etching where the wafer surface has been exposed. Several masking techniques suitable for MEMS wafers that have been developed by Panasonic can be offered. The throughput of Plasma Dicing depends principally on the thickness of the wafer, and is independent from wafer size, chip size and chip shape. By utilizing Plasma Dicing for MEMS, higher throughput and higher quality than conventional dicing can be achieved. As market trends demand smaller-and-smaller chip sizes—as is typical for MEMS devices—Plasma Dicing offers many benefits when compared to those of conventional line-by-line dicing methods; especially in terms of cost savings and quality increases.Patented techniques, processes and new equipment developed by Panasonic allow for low cost-of-ownership Plasma Dicing of MEMS wafers, and will be discussed in this paper.

Advanced black resist processing and optimized lithographic patterning for novel optical MEMS devices

Bozena Matuskova

Abstract
Highly functional optical materials are getting more and more attention in the photonics’ applications, particularly shielding materials and IR-related materials for optical MEMS applications. As the complexity of the photonic devices is increasing together with the optical performance, advancements in the materials and according lithographic patterning are demanded. These innovative materials show promising parameters taking the advantage of micro-dispersion technologies of ultra-fine pigments and photopolymer technologies. In this paper, the advanced resist processing and parameters of a new black material designed for miniaturized photonic devices from FFEM and optimized lithographic patterning is discussed. Resist processing methods including spin and spray coating are combined depending on required optical performance.. The UV light penetration of the coated substrate with functional black resist layer in the NUV spectrum range is limited. The absorption level of the material is already significant in the upper part of the layer closer to resist surface preventing the light from transmission to the underlying resist during the exposure. This affects the final resist polymerisation. As a consequence, the resist development process becomes challenging with the risk of introducing patterning, delamination defects or not fully resolved structures. Therefore an enhanced adjustment and further precise control of the development process is necessary in order to secure overall performance capabilities. The joint collaboration of FFEM black material division and EV Group process development enabled high precision black resist processing and optimized high resolution lithographic patterning of advanced photonic devices. The goal of this paper is to present the obtained results and augmented lithographic processes established for current and future optical MEMS applications
