Title: Manufacture of semiconductor device
Inventor: OSA YASUNOBU
IPC: H01L29/788
Filed: 1983-11-28
Abstract: PURPOSE:To obtain an EPROM memory cell which unnecessitates to take the margin for mask alignment and is fitted to high integration by forming poly Si's of the first and second layers in self-alignment, and forming the first layer poly Si field SiO2 in self-alignment. CONSTITUTION:An Si layer 4 is formed on the first oxide film 3 of an Si substrate 1, and an oxidization resistant mask layer 5 having a fixed pattern is formed on this Si layer. After each process, the surface of an Si member is selectively oxidation-treated with the mask layer 5, resulting in the formation of an integral body with the oxide film 3, and then forms an oxide film thicker than it. In other words, the first poly Si layer 4 (floating gate) and the field oxide film 2 are manufactured in self-alignment, and there is no overlap therebetween. Since the end parts of the first poly Si layer 4 and the second poly Si layer 6 are also photo-etched with the same photomask, the mask for mask alignment is unnecessary. Thereby, in the case of the same accuracy of working, the size of the cell can be reduced.
