LDMOS device with self-aligned resurf region and method of fabrication
摘要:
A RESURF LDMOS transistor (64) includes a RESURF region (42) that is self-aligned to a LOCOS field oxide region (44). The self-alignment produces a stable breakdown voltage BVdss by eliminating degradation associated with geometric misalignment and process tolerance variation.
