Medical MEMS: SQZ Biotech raises $65 million to develop cell therapies

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.
