Title: Vertical insulated gate type transistor
Inventor: NISHIURA AKIRA
IPC: H01L29/78
Filed: 1988-10-06
Abstract: PURPOSE:To suppress increase of the ON-state resistance and the gate threshold voltage by forming vertical gate insulating films and gate electrodes of specific depth having side faces in contact therewith. CONSTITUTION:N<+> layers 5 are formed in a surface area between gate electrodes 7 except the contact part of a P<+> layer 4 and a source electrode 8. Therefore, the length of channels is the same as the depth of the gate electrodes 7 to fix the length of the channels to one value, suppressing increase of the channel resistance. Even if high concentration of an impurity is contained in the surface area of the P<+> layer 4, the N<+> layers 5 extend horizontally on the surface thereof and the channel C extends vertically therein in the direction of gradually lowering impurity concentration to suppress increase of the gate threshold voltage.
