Cambridge CMOS Sensors (CCMOS) says it is seeing increasing sales of its gas-sensing microsystems and is on the cusp of more major contracts. Gas-sensing technology has a broad range of applications, including domestic gas detectors, industrial safety, explosive detection, medical diagnostics and environmental monitoring. A Cambridge University spin-off that recently raised an additional £4.5m, the company was just named “Start-up of the Year” by BusinessWeekly.

Its sensors use high-temperature tungsten MOSFET heaters embedded in an SOI membrane. These effectively form a micro-hotplate that heats the sensing material, allowing it to react with gas molecules. Crucially, CCMOS’ MOSFETs can be fabricated in a commercial SOI-CMOS process and therefore can be fully integrated with the associated drive/detection circuitry. The devices can be heated from room temperature to 700°C in a fraction of a second and have the ultra-low power consumption suitable for battery operation.

With the upcoming Hybrid Memory Cube (HMC) from Micron et al, SOI becomes an integral part of 2.5D and 3D stacks, notes SemiMD’s Ed Sperling. “The logic base layer—in this case made by IBM—uses an SOI substrate,” he explains, “…even if some of the other pieces use different materials.” He goes on to say that while the next-gen HMC enters production at the end of next year, in the meantime the existing HMC architecture can be attached to FPGAs, either in a vertical stack or in a 2.5D configuration. “Having an additional layer of insulation is a bonus in that architectural arrangement, as well, to buffer against a variety of physical effects ranging from noise to heat.”

SiT_TempFlat_MedResSiTime, which leverages SOI for high-performance MEMS timing solutions, has introduced TempFlat™ MEMS. Until recently, all MEMS oscillators used compensation circuitry to stabilize the output frequency over temperature. SiTime’s TempFlat MEMS is a revolutionary breakthrough that eliminates temperature compensation, resulting in dramatically higher performance, smaller size, lower power and cost, says the company. According to the industry research firm Yole Développement. the silicon MEMS oscillator market is expected to grow at a CAGR of 60% to $467M in 2018 and is one of the top three growth areas in the MEMS industry

More than 65 percent of substrates used in fabricating switches for handsets are SOI based, according to the industry research firm Yole Développement. This shows the massive adoption of RF SOI for this booming electronic market experiencing double-digit growth.  Soitec, the world’s leading manufacturer of SOI wafers, says that this shows that SOI-based technologies are now mainstream for manufacturing switches and antenna-tuners, key RF components used in all cell phones and tablet computers.

An RF SOI substrate has an active layer on which CMOS transistors are built, isolated from a high-resistivity silicon base layer. This reduces noise and interference, helping the finished die reach its target performance in terms of signal integrity, handling RF power and integration density. SOI technologies enable devices to reach a figure of merit for on-series resistance and off-equivalent capacitance (Ron.Coff ) below 200 fs (femtoseconds) with potential for further reduction. This directly relates to improved device performance and smaller die size.

On the strength of recent demonstrations, Soitec indicates that power amplifiers will likely be the next RF components based on SOI. The technology enables highly tunable amplifiers to address multi-region requirements on a single platform. In addition, the RF SOI substrates offer a path towards further integration, such as more mixed-signal and digital content.

STMicroelectronics says its new manufacturing process, known as H9SOI_FEM, allows production of complete integrated front-end modules. This process is an evolution of the H9SOI SOI process, a groundbreaking technology introduced by ST in 2008 and subsequently used by customers to produce more than 400 million RF switches for mobile phones and Wi-Fi applications. Building on that experience, ST has optimized H9SOI for creating integrated front-end modules, resulting in today’s announcement of H9SOI_FEM offering the industry’s best figure of merit for antenna switch and antenna tuning devices with Ron x Coff at 207fs2 . ST has also invested to ensure suitable manufacturing capacity for even the most demanding of customers. The new process greatly reduces size of multi-band radios for 4G and other high-speed wireless connections.

The H9SOI_FEM process is a 0.13µm technology with dual-gate 1.2V and 2.5V MOSFETs. Unlike conventional SOI processes, such as those used for discrete devices like RF switches, H9SOI_FEM supports multiple technologies such as GO1 MOS, GO2 MOS, and optimized NLDMOS. This allows H9SOI_FEM to support full monolithic integration of all key functions of an RF front end, which comprise RF switches, Low Noise Amplifier (LNA), multi-mode multi-band cellular Power Amplifiers (PAs), diplexers, RF coupling, antenna tuning and RF energy-management functions.

H9SOI_FEM is suitable both for devices targeting the low end of the market, where low cost and extensive integration are crucial, as well as the high-end smartphone segment. High-end products typically require a combination of many frequency bands to support not only 2G, 3G and 4G standards, but also various other wireless connectivity standards such as Bluetooth, Wi-Fi, GPS and NFC (Near-Field Communication) for contactless payments.

FleX-Silicon-on-Polymer-ICAmerican Semiconductor has announced the FleX-MCU™ product family. Leveraging an SOI starting wafer, the FleX-MCU is the world’s first physically flexible microcontroller fabricated using the FleX™ Silicon-on-Polymer™ process. The FleX-MCU is an 8-bit RISC microcontroller with 8KB embedded RAM operating up to 20MHz, and is the initial product for a full portfolio of physically flexible ICs. The FleX IC roadmap includes microcontrollers, analog-to-digital converters (ADC), radio frequency (RF) wireless communications, and non-volatile memory (NVM).

“The Silicon-on-Polymer process can be applied to a variety of standard SOI wafers from any commercial wafer foundry or IDM. The FleX-MCU demonstrates a standard foundry process used to develop physically flexible FleX ICs. This means customers can create their own custom FleX ICs in addition to using our catalog products,” said Rich Chaney, General Manager of American Semiconductor

The FleX-MCU is fabricated in TowerJazz Semiconductor’s CS13 process. The CS13 PDK can be used to design flexible ICs; the IP blocks used in the FleX-MCU are available from American Semiconductor for customers to include in their custom designs.

In a previous announcement, Dr. Marco Racanelli, Sr. Vice President of TowerJazz said, “FleX is a post-fabrication process that can be applied to our production SOI technology making it possible to turn any product into a flexible die helping our customers create new, differentiated solutions. We are excited to partner with American Semiconductor and look forward to jointly participate in the growth of this new market.”

Scellpicture-240Soitec has announced the industry’s first four-junction solar cell for concentrator photovoltaic (CPV) systems, entering the industry’s roadmap at a world-class level with 43.6 % efficiency. Soitec is best known as the world’s leading producer of SOI wafers for microelectronics. For the new generation of optimized III-V-based multi-junction solar cells, Soitec has leveraged its proprietary semiconductor-bonding (Smart Stacking™) and layer-transfer (Smart Cut™) technologies and collaborated with Fraunhofer and Leti.

Soitec’s CPV modules are built on Concentrix technology, using Fresnel lenses to concentrate sunlight 500 times and focus it onto the tiny, highly-efficient multi-junction solar cells. Different types of solar cells are stacked on top of one another, with each cell type designed to convert a certain range of the solar spectrum: short wave radiation, medium wave radiation and infrared. The current generation of this technology is triple junction, achieving module efficiency of 30% — almost twice as high as the efficiency of conventional silicon photovoltaic modules.

To reach 43.6 % efficiency, Soitec’s innovative new four-junction cell uses two new, highly sophisticated dual-junction sub cells grown on different III-V compound materials, which allows optimal band-gap combinations tailored to capture a broader range of the solar spectrum. This maximizes energy-generating efficiency, and puts the company on track to be the first to reach the target of a 50% cell efficiency level.
