hi, i'd like to ask what's the temperature limits of technology based on Si and GaAs. Also I'm interested in silicon-nitride thermal conductivity properties, cause they are in wide range and depend on deposition technology. Is it possible to apply silicon-nitride layer with high thermal conductivity on GaAs structure? In my knowledge, on Si3N4 it is necessary to perform high-temperature operations to obtain the good thermal conductivity properties.

thanks for help

i hope, this topic will not fade out as usually..
