To date, over 40 readers have commented on Handel Jones’ (IBS) EETimes post entitled FinFETs Not the Best Silicon Road (read post here).  He noted that, “…next-generation 20nm bulk high-K metal gate CMOS and 16/14nm FinFET process will deliver smaller transistors. However, they will also have a higher cost per gate than today’s 28nm bulk HKMG CMOS…”.  He then went on to say, “One option […] is fully depleted silicon-on-insulator (FD SOI). It gives lower cost per gate and lower leakage than bulk CMOS and FinFETs.”

Synopsys has announced that STMicroelectronics has standardized on Synopsys’ IC Compiler™ place-and-route solution for all its CPU and GPU implementations inside its Design Enablement and Services organization.  As noted in the press release (read here) ST has a unique processor architecture made possible through their FD-SOI process technology.  An FD-SOI device can operate at significantly higher frequencies than an equivalent, traditional, bulk CMOS device. It can also run very fast at low voltages, providing much higher energy efficiency. The close collaboration between the ST design teams and Synopsys has led to a compelling implementation solution that fully exploits the performance and power promise of FD-SOI technology and provides the throughput needed to meet tight time to market windows.

Sans titre

The University of Washington’s Nanofabrication Facility (WNF) is the first North American institution to get an AltaCVD™ chemical vapor deposition (CVD) system (press release here). The AltaCVD system uses pulsed deposition technology to offer a unique combination of capabilities for developing new materials. It can perform atomic layer deposition (ALD) for exceptional 3D coverage at deposition rates matching those of more conventional CVD techniques. The system will be used by both internal and external researchers in fabricating a broad range of semiconductor-based devices including leading-edge CMOS transistors, MEMS, ICs built with the latest in through-silicon-via (TSV) technology, advanced LEDs and solar cells. Altatech is a subsidiary of Soitec (the world leader in SOI wafer manufacturing). AltaCVD systems have been used extensively in R&D and pilot production facilities throughout Europe; however, the University of Washington’s order represents the first such system to be delivered to a North American university R&D and pilot production facility.

Dr. Michael Khbeis, acting director of the WNF, said, “The AltaCVD system provides a unique capability that enables researchers to deposit conformal metal films for TSV applications as well as metal oxides and nitrides for high-k dielectrics and piezoelectric materials. The higher deposition rate enabled by pulsed CVD makes ALD films a tractable solution for scale-up paths toward high-volume manufacturing for our researchers and industrial clients. This ensures a viable pathway from academia to real economic impact in our region.”

Tronics_SOI_MEMS      Leti_NMEMS_Ultimes_V2

A year after announcing the industrialization of CEA-Leti’s breakthrough M&NEMS technologies, Tronics has successfully designed and manufactured the first batch of six-degrees-of-freedom (6DOF) MEMS chips, with 3 accelerometers and 3 gyroscopes on a single die (press release here). Built on SOI wafers, with a die size of less than 4mm2, this 6DOF MEMS chip is one of the smallest in the industry, and Tronics says further optimization will make it the smallest. Besides its size advantage, the piezoresistive nanowire based technology significantly decreases power consumption and allows manufacturing of all sensor types (accelerometers, gyroscopes, magnetometers, pressure sensor and microphone) using a common process flow.

This first functional batch is an important milestone towards high volume production. The industrialization work will continue through 2014, with the first commercial samples available in Q4 2014. An ASIC is also being designed and will be available in 2014 to complete the sensor platform. In addition to the 6DOF device, Tronics has also designed a very compact 9DOF monolithic MEMS. Samples will be available by the end of this year.

Target applications for this new generation of inertial devices are those where size and/or power are key: wearable devices, smartphones and tablets.

Eveon and CEA-Leti have demonstrated liquid-pumping for smart drug delivery in the bolus mode using a silicon-based micro-pump fabricated with a standard MEMS process. (Read full press release here.)

The milestone is the first functional micro-pump integration using MEMS standard process on Leti’s 200mm line. It is a result of FluMin3, Eveon and Leti’s three-year joint-development project to produce an automatic drug-delivery system integrating a MEMS micro-pump that reduces patient discomfort by delivering medicine with very high accuracy, minimal loss and high flow rates.

The micro-pump is based on core technology initiated by Eveon and IMEP-LAHC. The pump demonstrator is made from SOI wafers, which include a thin deformable membrane sealed over a fluidic cavity and fluidic valves determining inlet and outlet. A dedicated electromagnetic actuator developed by Cedrat Technologies shapes the membrane.
