Abstract
The semiconductor industry has established integrated design environments based on PDKs (Process Design Kits), standard cell libraries, memory architectures, and IP. This design infrastructure is a key success factor, providing easy access to CMOS technology for IC designers, and increasing the chance of first-pass successful silicon. Can these features and benefits be brought to MEMS product designers? MEMS-based component suppliers want to reduce their time to market and rapidly ramp their designs into high-volume production, by reducing design spins and fabrication cycles. At the same time, a new MEMS design often requires process development not typical in CMOS design. While the prior MEMS rule “one process, one product” has become weaker over the last few years, MEMS design tools must still be very much “process aware” and adaptable to process modifications. Ideally, a design environment and design methodology for MEMS should enable efficient re-use of technology and design knowledge while supporting manufacturing process changes and design optimization. We will present a new methodology for MEMS design that uses MEMS Process Design Kits. These PDKs can be the “golden” container for MEMS technology and design information, and increase the chance for first-pass successful silicon. Based upon proven technologies from X-FAB and CEA Leti, we will share examples of MEMS component libraries that contain multi-physics compact models (rigid or flexible shapes for masses and membranes, electrostatic combs, piezo resistive gauges, suspension beams) and demonstrate how these models and libraries enable the reuse of characterized structures across multiple designs. We will then demonstrate how a parameterized and interactive component library, combined with a MEMS PDK interface, can facilitate the adaptation to foundry specific processes, provide designers with the ability to quickly explore a broad design space, and optimize designs for performance and manufacturing.

Abstract
Early detection of gas phase chemicals can ensure product integrity, and human safety. New types of chemical sensors are being developed that are sensitive, selective and rapid for direct vapor detection of hazardous chemicals. These next generation chemical sensors are based on novel organic nanofiber materials that demonstrate photoconductive and chemiresistive responses to surface adsorption of chemicals. The nanofibers are prepared via self-assembly of building-block, core molecules that are uniquely functionalized with a variety of tail and head groups that enable sensitive and selective binding and electron transfer interaction with different chemical analytes. When placed on a substrate, nanofibers form a porous super-net structure with large surface area and high porosity that can capture target molecules from the air through molecular diffusion and surface adsorption. Upon capture the electron density associated with the nanofiber structures can either increase or decrease resulting in an observable change in electrical conductivity that signals a detection event. For enhanced selectivity nanofibers of different chemical functionality can be deployed in sensor arrays. In addition to selectivity, the nanofiber sensors are also highly sensitive. Certain chemical species have been detected at the low parts per trillion (ppt) level. Nanofiber sensors are particularly sensitive to amines, aldehydes, volatile organic compounds, and toxic industrial chemicals. Vaporsens, Inc. has developed autonomous nanofiber chemical microchip sensors and sensor arrays that can be deployed in small portable detectors and/or fixed distributed networks. Nanofiber chemical sensors can deliver lower limits of detection and faster response times than other commercially available chemical sensors.

Abstract
Globalization, Industry 4.0 and increasing price pressure are only a few impact factors influencing the competition in the capital goods industry. There is a trend for machine builders to differentiate by creating individual bundles, consisting of technical products and lifecycle-oriented services, called Product-Service Systems (PSS). Smart sensors are a key enabling technology for availability-oriented PSS. Within the German state-funded R&D project “InnoServPro”, Sensitec GmbH is working with a number of partners to develop innovative service products for individualized, availability-oriented business models. One use case studied concerns the condition monitoring of the primary conveyor belt of a potato harvester. A specially-developed magnetic MEMS sensor, based on the magnetoresistive (MR) effect, is capable of identifying damage to steel rods, which are a major component of the conveyor. This information is used to estimate the remaining useful life of the conveyor, in order to plan maintenance optimally and so increase machine available. These new technologies are already progressing to industrial applications. In tobacco cutting machines the cutters are typically re-sharpened at fixed periods. A new MR-based magnetic sensor is capable of monitoring the sharpness of the cutters to allow local, in-process re-sharpening of the cutters without stopping the machine. This solution provides significant benefits, in terms of increased machine availability due to reduced down-time for re-sharpening the cutters. There are also unexpected additional benefits for the machine builder. The magnetic measuring principle can recognize original OEM-cutters so preventing machine down-time due to use of lower quality, non-original components. New magnetic sensors, based on the MR effect, combined with new software functions for smart signal processing are proving an essential enabling technology for new product-service-systems that benefit both end-users and machine builders.
