In 1984 ICSSDM, Kobe, we already reported the development of 1200V, 75A bipolar-mode MOSEs(BIFET[l], or called IGT, COMFET [2,3]), which could turn-off 75Amps drain current with lOOOV applied drain voltage at the elevated temperature, 125 C(see Fig. 1). This paper presents improved BIFETs with non-latch-up structure as well as a large ASO. Figure 2 shows a cross section of a new BIFET. A part of the source layer is periodically eliminated, providing a low resistance bypass for holes to the…
