Abstract
N-channel LDMOS and p-channel MOS devices for high voltage integrated in a BiCMOS integrated circuit and exploiting a RESURF condition are provided with a buried region of the same type of conductivity of the epitaxial layer and a doping level intermediate between the doping level of the epitaxial layer and the doping level of a well region. The devices may be configured as source or drain followers without problems.
