Abstract:

Honeywell is developing and has introduced the first products of the HTMOS(trademark) product line, which is targeted for use in systems operating in severe high-temperature environments. The HTMOS(trademark) line of electronic products incorporates Honeywell's oxide-isolated high-temperature process and high-temperature circuit design methodologies. These components are being developed to meet applications in instrumentation, data acquisition, and control where hostile environments require a large temperature range of -55 to +225 (degrees)C with an extended operating life of 5 years at elevated temperatures. Honeywell has introduced a quad operational amplifier, quad analog switch, an 8-bit microcontroller, and a 32 Kx8 SRAM. Additional products are planned for introduction in 1997. This paper will discuss the high-temperature features of the silicon on insulator, SOI, process technology and product design approaches for reliable high-temperature electronic components. The paper will also discuss the existing product performance in a high-temperature environment.
