SOI for hostile environment applications

SOI technology has been used for niche applications long before it became mainstream. High-temperature electronics and radiation-hard circuits are probably the two most important of these niche markets. SOI transistors are inherently more resistant to most harsh environments than bulk devices because they contain a smaller volume of silicon. Novel devices such as double-and multiple-gate SOI devices offer the potential of being even more resistant to harsh environment conditions than single-gate devices.
