摘要:
A method for forming thin oxide portions in electrically erasable and programmable read-only memory cells, including the use of the enhanced oxidation effect and the lateral diffusion of heavy doping, for obtaining a tunnel portion whose dimensions are smaller than the resolution of the photolithographic method used.
