BI-DIRECTIONAL POWER SWITCH

摘要

A semiconductor device that is comprised to two or more MOSFETs to form a bi-directional power switch. One embodiment of the bi-directional switch is comprised of (a) a semiconductor substrate having an upper surface and a lower surface; (b) a first region of a first conductivity type in said semiconductor substrate and proximate to said upper surface; (c) a first source region and a second source region of a second conductivity type within said first region; (d) a drain region of a second conductivity type formed within said first region and proximate to said upper surface and between said first and second source regions; (e) a first source overlaying and connecting said first source region; (f) a second source overlaying and connecting said second source region; (g) a first gate above said upper surface and placed between said first source and said second source wherein said first gate overlays a portion of said first source region and said drain region; (h) a second gate above said upper surface and placed between said second source and said first gate wherein said second gate overlays a portion of said second source region and said drain region.
