摘要:
An area of a narrow interval between neighboring insulating gates and an area of a wide interval are provided and in the area of a wide interval, a p-type well layer deeper than a p-type base layer is provided. By use of this constitution, even if an area of a narrow interval between neighboring insulating gates and an area of a wide interval are provided, the withstand voltage will not be lowered.
摘要:
A power semiconductor module comprises a power circuit portion having a power semiconductor chip (113, 111) located on an upper surface of a base (108) having a case (500) on an outer periphery of the base; a printed board (102) with a circuit component mounted thereon, located above the power circuit potion with a space therebetween; a supporter (1031, 1032) which couples the printed board (102) with a cover plate (105) located on an upper portion of the case (500); and silicon gel (101) which is filled in the semiconductor module. An elastic coefficient of all or part of the printed board (102) is smaller than that of the cover plate (105).

An area of a narrow interval between neighboring insulating gates (7) and an area of a wide interval are provided and in the area of a wide interval, a p-type well layer deeper (9) than a p-type base layer is provided. By use of this constitution, even if an area of a narrow interval between neighboring insulating gates and an area of a wide interval are provided, the withstand voltage will not be lowered.
