Microsemi, Honeywell et al Leveraging SOI to Curb CO2 Emissions

The furnace in your home’s basement might not be as sexy as your smartphone, but when it comes to making a difference to the planet, it’s awfully important. That’s why Microsemi and Honeywell have teamed up with Cissoid, Cambridge CMOS Sensors and several top universities like UCL, Cambridge and Warwick in a €4 million ($5.3 million) 3-year European research program called SOI-HITS that’s developing high-temperature smart gas sensors to make furnaces more efficient.

Furnaces? Well, consider that in the average UK home, 85% of the energy consumed is by the boiler (the British term for a home furnace). It turns out there are about 40 million domestic boilers in the EU with a growth rate of 15% per year. This project aims to save 15% in energy consumption in the domestic boiler industry, which will save 3.6 billion Euros per year – a nice ROI.

Sensors in general are a high-growth market – currently growing at 79%, enroute to hit $43 billion in the next two years (per Markets and Markets).

The sensor tech developed in this program can reach far beyond the furnace.  As high-temp specialist CISSOID’s CTO, Pierre Delatte, points out, “Thanks to the results of the SOI-HITS project, high temperature sensors will soon benefit from highly integrated and accurate electronic interfaces, offering unmatched reliability and reducing the cost of ownership in industrial, aerospace and automotive systems.”

To do this, you’ve got to use SOI. Long-time ASN readers will know that high-temp apps were one of the original drivers of SOI decades back, and Honeywell was one of the pioneers.  If you want to understand why SOI is so good for high-temp, Honeywell has a really good, clear explanation here.

SOI-HITS Proposal

To reduce both energy consumption and waste gas emissions, the SOI-HITS partners are developing innovative CMOS-compatible, SOI integrated smart microsensor systems, capable of multi-measurement (water vapour, temperature, gas, flow, UV/IR) and detection under harsh environment conditions (to 225oC, high water vapour level).  That means extending operating temperature to a minimum of 175oC (targeting 225oC), extending operation life to minimum 10k hours (targeting 50k hours) – all while reducing the cost of packaging and assembly methods to under $10.

According to the project summary, “The smart multisensor chip will comprise multiple micro-hotplates with tungsten micro-heaters onto which selective nanostructured and thin film metal oxide sensing layers have been deposited. For the gas sensors (CO2 (concentration 6-10%, CO (0-1000ppm), and H2S (0-100ppm)), we will achieve fast thermal response time of a few ms and loss per micro-hotplate below 0.2mW/oC. Water vapour sensors, flow sensors (for liquid & gas) and precision on-chip temperature controllers will be also integrated. On-chip processing electronics, including drive circuitry, filters, amplifiers, processing circuits and analogue to digital interfaces, operating at 225oC, will be developed. The extension of the SOI platform to optical detectors, such as UV photodiode flame detectors and IR combined sources/detectors, will be explored. Finally development of a High Temperature SIP (system in a package) will enable real-world demonstrators.”

The program finishes up next year, but this summer the partners presented an update during a workshop at the Transducers conference in Barcelona.  The presentations are all available here.

It’s very cool (or hot!) stuff. And good for the planet.

Spotlight on FD-SOI & FinFETs at Upcoming IEEE SOI Conference
(1-4 Oct. in Napa – register by 17 Sept. for best rate)

The 38th annual SOI Conference is coming up in just a few weeks. Sponsored by IEEE Electron Devices Society, this is the only dedicated SOI conference covering the full technology chain from materials to devices, circuits and system applications.

Chaired this year by Gosia Jurczak (manager of the Memories Program at imec), this excellent conference is well worth attending. It’s where the giants of the SOI-related research community meet the leading edge of industry. But there are also excellent courses for those new to the technology. And it’s all in an atmosphere that’s at once high-powered yet intimate and collegial, out of the media spotlight.

This year it will be held 1-4 October at the Meritage Resort and Spa, a Napa Valley luxury hotel and resort, set against rolling hills with its own private vineyards. Finding the right spot for this conference is key. One of the things that people really like about it is that in addition to the excellent speakers and presentations, the locations are conducive to informal discussions and networking across multiple fields. This year’s spot looks like the perfect setting, with easy access to Silicon Valley.

The Conference includes a three-day Technical Program, a Short Course, a Fundamentals Class, and an evening Panel Discussion. Here’s a look at what’s on tap for this year.

(To register at the discounted rate, be sure to send in your registration by September 17th. You can get the pdf of the full program & registration information from the website.)

The courses & panel

Short course: Design Enablement for Planar FD & FinFET/Multi-gates (chaired by UCL & Leti) The conference kicks off on Monday with six sessions by experts in technological trends, the physics of fully depleted devices, technology design kits as well as digital, analog and RF designs specific for FD-SOI.

The fundamentals course: FinFET physics (chaired by Intel): on Wednesday afternoon, three hour-long sessions will give comprehensive insights into the physics and processes related to multi-gate FETs.

Panel: Is FinFET the only option at 14nm? (chaired by Soitec) Following the always-popular Wednesday evening cookout, the panel discussion is a lively favorite event. This year’s invited distinguished experts will share their views on the industry’s FinFET roadmap.

All in all, it’s a great event. If you go, why not share your impressions on Twitter with #SOIconf12, @followASN and @IEEEorg? And of course ASN will follow-up with summaries of the top papers in our PaperLinks section. See you there?
