Abstract
A method of manufacturing a lateral insulated gate field effect transistor comprises the steps of forming a projecting portion on a first major surface of a semiconductor substrate, forming a pair of gate portions each of which is formed in each side of the projecting portion, forming an insulating layer on the resulting surface of the semiconductor substrate by burying the projecting portion and the pair of gate portions, and removing the semiconductor substrate from a second major surface of the semiconductor substrate to a position of the insulating layer in which the projecting portion is buried to expose the bottom surface of the projecting portion.
