Abstract In this paper we review the development of CMOS compatible gas sensors, introduce the recent concept of SOI smart gas sensors, and discuss in detail the advantages/disadvantages of micromachined SOI technology compared to bulk technology. We begin by discussing the concept of integrated sensors and the need for low-cost, reliable and battery-operated gas-sensing systems. We continue with a review of the main types of CMOS-compatible gas sensors together with their advantages/drawbacks and future challenges. We introduce SOI technology and describe its importance in microelectronics followed by a detailed discussion of its use as a generic platform technology for gas sensors. Finally, we present a brief report on our novel approach to making high-temperature low-power (HTLP) SOI gas sensors using CMOS micro-FET heaters.
