CONCLUSION
STMicroelectronics Italy, Catania has a long history in Power Transistors design and
manufacturing including MOS-FET, IGBT, Bipolar.
Rad-Hard design knowledge acquired in past years has achieved a sufficient expertise
in Rad-Hard technique and technology development.
Almost all consolidated Power technologies have been assessed in radiation environment
and part of them selected for Space.
To reduce time for development, validation and qualification, the target-spec should be
defined with contribution of final users:
Electrical
Radiation test (TIS, SEE, SEB,…)
Qualification type (agency, according to, COTS+, ….)
Open to support application requirement and specific parameters definition.
