Title: Insulated gate field effect transistor
Inventor: HIRASHIMA KUNIHIKO
IPC: H01L29/78
Filed: 1978-12-28
Abstract: PURPOSE: To completely prevent a pinch-off phenomenon by extending a gate electrode through a thicker insulating film than the gate insulating film at the portion corresponding to off-set of the channel of an insulated gate field effect transistor (FET).  
     CONSTITUTION: After an n + -type layer 4 is formed through an opening perforated at an oxide film 11 of a p-type silicon substrated 1, the substrate 1 is coated with a gate oxide film 6 and a field oxide film 8. A small hole for drain contact is formed at the film 8. Then, polycrystalline silicon layers 3, 5 and 7 are selectively formed on the substrate 1, and phosphorus is added in high density thereto. Thus, an n-type drain layer 2 is formed thereon. Again the layer 2 is coated with an oxide film, and selectively perforated with openings and aluminum wires are connected therethrough. At this time, a part 10 of the aluminum wire is extended onto the off-set portion between the gate electrode 5 and the drain layer 2 to form thereby an off- set gate 10. According to this configuration, it retains sufficiently the insulating allowance between the drain electrode 3 and the gate electrode 5. Further, it can prevent a pinch-off phenomenon of the channel by the off-set gate 10
