MIPI Alliance completes development of a new sensors standard for automotive applications

The MIPI Alliance, an international organization that develops interface specifications for mobile and mobile-influenced industries, recently announced that development has been completed on MIPI A-PHY v1.0, a long-reach serializer-deserializer (SerDes) physical layer interface for automotive applications. The specification is undergoing member review, with official adoption expected within the next 90 days. A-PHY will provide a physical layer for data transfers spanning an entire vehicle. As the first standard of its kind, it will help the automotive industry accelerate the availability of advanced driver assistance systems (ADAS), autonomous driving systems (ADS) and other surround-sensor applications, including cameras and in-vehicle infotainment (IVI) displays.

SQZ Biotechnologies (SQZ), a clinical stage cell therapy company developing innovative treatments for multiple therapeutic areas, announced this week the completion of a $65 million Series D preferred stock financing. The round was led by Temasek with participation from another new large, US-based fund as well as additional participation from existing investors, including GV, Illumina Ventures, Invus, JDRF T1D Fund, NanoDimension, and Polaris Partners. The company also announced the expansion of its cellular vaccine platform, currently in trial for oncology, into infectious diseases, and development of a point-of-care system to potentially generate patient product directly at treatment centers.

MEMS foundry X-FAB invests $25 million to expand silicon-based microfluidics offering

X-FAB Silicon Foundries announced this week that it has taken steps to simplify the integration of microfluidic elements with CMOS and SOI die. As part of the company's MEMS-oriented technology offering, X-FAB is now able to provide a larger variety of process capabilities for silicon based microfluidic systems. X-FAB has been focused on a more standardized foundry approach, to remove barriers to market entry and shorten development cycles. X-FAB has made $25 million worth of investment in the area of microfluidics in the past 5 years, while taking on numerous projects for medical and industrial clients for applications such as lab-on-a-chip, DNA sequencing and synthesis, and cancer diagnostics. Through these projects, X-FAB has expanded its expertise in areas like noble metal processing, high aspect-ratio deep reactive ion-etching (DRIE), and the deposition of both organic and inorganic materials. X-FAB says it also has become adept at tailoring the interfaces needed to connect CMOS die and the accompanying microfluidics elements, so the exact application requirements can be met.

SilTerra offers monolithic PMUT process option on CMOS for emerging ultrasonic sensing applications

SilTerra, a Malaysian-based global semiconductor and MEMS foundry, announced this week the availability of the piezoelectric micromachined ultrasonic transducer (PMUT) process option on CMOS platform. Customers can now design their transducers for ultrasonic sensing applications using the monolithic PMUT process design guidelines from SilTerra.  As a part of SilTerra’s initiative towards the mass production of the MEMS-based PMUT devices, SilTerra developed and qualified the PMUT cells in a modular concept similar to other CMOS process options such as SRAM, MIM, and HRPoly.  MEMS designers and ASIC designers thus have the flexibility to use these CMOS and MEMS process design guidelines to develop their prototypes and accelerate time to volume production.

Mosaic Microsystems secures $2 million seed round from BlueSky Capital and Corning

Mosaic Microsystems is focused on providing thin glass substrates and through glass vias (TGVs) for RF communications devices, particularly for 5G, as well as MEMS and sensors for the internet of things (IoT) and has reported a significant investment into the business.  The company recently raised $2 million in a seed round led by BlueSky Capital, with participation from Corning. Jeremy Wooldridge, General Manager of Samtec Microelectronics, will join Mosaic’s Board of Directors. In 2019, Mosaic secured an exclusive license from Corning for thin glass handling solutions, as well as an NSF SBIR contract to establish manufacturable implementation of thin glass for electronics packaging. Mosaic leadership team includes technology experts from Kodak, Corning, and ON Semiconductor.

MEMS technology innovator NextInput enabling superior HMI experiences

MEMS and sensors are the key enablers for the continuously evolving human machine interface (HMI) technologies. NextInput, a leader in this technology segment, has been successfully deploying turnkey HMI solutions, including its MEMS force-sensing technology, for customers in the automotive, consumer, mobile, wearable, and industrial markets. We recently spoke with NextInput’s CEO and Founder Ali Foughi about emerging HMI trends, competitive landscape, commercial traction to date, and his vision for the company.

MEMS timing device maker SiTime files to go public to raise $100 million

SiTime, a market leader in MEMS timing devices, announced last week that it has publicly filed a registration statement with the U.S. Securities and Exchange Commission (SEC) relating to a proposed initial public offering (IPO) of its common stock. SiTime had revenues of $101 million in 2017 and $85 million in 2018. For the nine months ended on September 30, 2019, the company reported revenues of $56 million, compared to $62 million for the same period in 2018. Barclays and Stifel are acting as book-running managers for the proposed offering. Needham & Company, Raymond James, and Roth Capital Partners are acting as co-managers for the proposed offering. The number of shares to be offered and the price range for the offering have not yet been determined. SiTime has applied to list its common stock on Nasdaq under the ticker symbol "SITM".

Thorlabs acquires chemical sensors maker Coda Devices

Thorlabs announced earlier this month that it completed the acquisition of Coda Devices, a manufacturer of Raman-based solutions for analyzing the chemical composition of substances within a laboratory environment or in the field. Based in Menlo Park, California with an R&D center and production in Moscow, Russia, the Coda team will be integrated into Thorlabs' Spectroscopy Technology Group in Munich, Germany. Coda's Raman spectrometers employ patented coded-aperture technology, which reportedly samples over 1,000 optical channels simultaneously, to achieve more than 30 times the light throughput of analogous diffraction slit spectrometers, thereby overcoming the light collection and overall sensitivity limitations of a small entrance aperture.

MEMS foundry Micralyne increases production capability with new SPTS tool

Micralyne announced this week the purchase of a cluster system from SPTS Technologies, a KLA company. Micralyne will use the new Versalis fxP tool equipped with a Rapier™ plasma etch module to increase production capacity in order to meet growing customer demand for its production of MEMS devices for biomedical, optical, and industrial applications. Micralyne is a leading provider of MEMS sensors and other microstructures that differentiate exciting applications such as Internet of Things (IoT) devices, implantable medical devices, and optical communications. The addition of SPTS' system will allow Micralyne to offer its MEMS customers a broader range of process technologies and production capabilities with improved throughput and yield.

Silicon Sensing expands MEMS foundry, aims to deliver five-fold increase in output

Silicon Sensing Systems announced that it will expand its MEMS foundry in Japan, moving into a new purpose-built facility, reportedly allowing the company to meet significantly increased demand for its MEMS inertial sensors and sputtered thin film PZT MEMS device wafers. The new facility will increase floorspace to 3,000 square meters, which will immediately more than double current wafer throughput and deliver scope for a five-fold increase in output over the next five years, in line with the company's current market growth predictions. To keep up with the volume and price pressures in the thin film PZT MEMS sector, Silicon Sensing said it is already expanding its 8-inch wafer line production. This expansion forms part of a major two-year investment program which will upgrade tooling, capabilities, and capacity, and comes as Silicon Sensing celebrates 20 years in the MEMS business during which time the company has delivered over 30 million devices worldwide.
