Semiconductor component with complementary metal-oxide-semiconductor (CMOS) circuit, with bulk terminals, via which current is determined in blocking direction of bulk diodes between doped troughs and base

摘要

CMOS circuit semiconductor body (1) comprises first conductivity doping, at least one trough (2), doped with second opposite conductivity and negative and positive MOS (NMOS, PMOS) transistors with terminals (S,D,G). There is electric terminal (9) on trough and electric terminal (10) on semiconductor body in region of base doping as well as circuit components which detect current or its increase between terminals in blocking direction, due to signs of conductivities, and trigger alarm or protection function.
