Microelectronics is a key technology used in more or less any application. With increasing complexity and demand for harsh environments especially for high temperature, standard electronic reaches its limits. Depending on the grade, integrated circuits are specified up to a maximum operation temperature up to 125 °C or even less. Nevertheless sensors and actuators are used in industrial process with high environmental temperature, while commonly deposited electronics are used, which requires additional space and results in loss of performance.
Fraunhofer IMS thin film Silicon-on-Insulator (SOI) CMOS technology allows to overcome the above mentioned limits. Due to dramatically reduced leakage currents, analog, digital and mixed-signal circuits become feasible for use in a considerably extended temperature range up to typical 250 °C and above. The process is equipped with a robust high temperature tungsten metallization instead of aluminum and therefore allows reliable operation at high temperature conditions. Besides the CMOS specific components the technology is equipped with non volatile memory based on EEPROM.
Based on this technology we realize integrated circuits for the extended temperature range up to typical 250 °C and above.
Develop new application together with Fraunhofer IMS or optimize existing systems with respect to performance, type of construction, or cooling by using HT ASICs.
