Title: Manufacture of semiconductor device
Inventor: YOKOGAWA SHUNJI
IPC: H01L29/78
Filed: 1985-02-13
Abstract: PURPOSE:To reduce junction capacity, by patterning selectively an insulating film which is formed on the entire face and a polycrystalline silicon pattern to form a gate electrode, and by introducing impurities into the substrate. CONSTITUTION:After a field oxide film 22 is formed on a given surface of a P-type silicon substrate 21 and a gate oxide film 24 is formed on the element region 23, a polycrystalline silicon pattern 25 wider than the gate oxide film 24 is formed on the gate oxide film 24. Next, after a CVD silicon oxide film 26 is formed on the entire face, resists 27 with a predetermined shape are formed on the oxide film 26. At this time, the resists 27 have a distance L corresponding to the channel length of the gate electrode on the area for the gate electrode to be formed. Since the CVD silicon oxide film 26 and polycrystalline silicon pattern 25 are etched away with reactive ion etching at the same time using the resists 27 as a mask, the source and drain regions can be formed in self alignment to the openings. Thus a semiconductor device having a increased junction withstanding voltage and high integration rate can be manufactured.
