Abstract
PURPOSE: To obtain a MISFET device by a pn reverse bias separation by forming an n-type bury layer by utilizing for a mask a field oxidization layer buried selectively in a p-type Si substrate face.
CONSTITUTION: A field oxidization film is buried by a double mask of an Si3N4 and SiO2 on a p-type Si, and an n-type epitaxial-layer 3 is laminated to form a field oxidization film 23 similarly. Successively, an SiO26, Si3N47 and SiO28 are laminated. Next, a p+epitaxial 9 is laminated to be covered with Mo, and a gate 15, lead 11 and capacity portion 36 are selectively formed by etching. Successively, a thermal diffusion is provided from an opening to form p+layers 13 and 14. Next, an SiO216 is covered, and an opening is selectively provided to form an Al electrode 18. According to such a process, a pn reverse bias separation is formed to easily establish a formation of an LSI or IC. The source and drain utilize the lead commonly. A conventional electrode having many failures can be removed, the manufacture of a device be easily established, and the composite integration circuit be also freely formed.
