ABSTRACT:
Insulated gate field effect transistors (10, 70) having independent process steps for setting lateral and vertical dopant profiles for source and drain regions. In a unilateral transistor (10) , portions (48, 50, 51, 55) of the source region are contained within a halo region (34, 41) whereas portions (49, 47, 52, 64) of the drain region are non contained within a halo region. The source region (60, 65) has a first portion (48, 51) for setting a channel length and a second portion (50, 55 ) for setting a breakdown voltage and a source/drain capacitance. The second portion (50, 55) extends further into the halo region than the first portion (48, 51). In a bilateral transistor (70), portions (84, 89, 90, 91) of the drain region (72, 87) are contained within halo region (75, 79 ).
