Some of the keywords that i can mention is LOCOS, Collector-Diffused Isolation. It has been very neatly explained in "VLSI Fabrication Principles" by S.K.Ghandhi. Cheers, Kiran

Hi, BJT can be form in cmos based on W and L and doping concentration. bipolar cmos technology can use same cmos and bjt.

Latch up mainly occurs only when N-well and P-substrate Impedances increase to very high. these can be avoided by using guaded ring structures and bury contacts..
