Title: Semiconductor device
Inventor: NOZAWA HIROSHI
IPC: H01L23/522
Filed: 1980-03-12
Abstract: PURPOSE:To obtain a semiconductor device with a high reliability having a flat surface by forming an element region surrounded with a conductive thick film poly Si on SiO2 having a thick film portion corresponding to a thick film section of a conductive poly Si stacked on an Si substrate through SiO2. CONSTITUTION:An SiO22 of 1,000Angstrom  and P-added poly Si3 about 0.6mum thick and an Si3N4 mask 4 are stacked on an N type Si substrate 1 and an ion is injected thereinto to form a channel stopper 5. Subsequently, oxidation is made so as to leave an SiO26 of about 6,000Angstrom  and an unoxidized layer 33 about 0.2mum thick therebeneath. After removal of the mask 4, windows are etched through the layer 3 and the layer 2 to make a gate oxide film 7 which covers the film 7. Thereafter, a gate electrode 8, a source 9, a drain 10 and an offset gate 11 are made of poly Si by a normal method and covered with an SiO212 on which electrodes 14-16 are applied. This facilitates the mounting of the electrode on the poly Si layer. A highly dielectric conversion with the SiO2 thick film can check the formation of an inverted layer while  smoothing the surface thereby eliminating disconnection.
