Filed: 1990-05-18
Abstract: PURPOSE:To simplify processes by a method wherein a side wall spacer is formed of PSG, phosphorus is doped by thermal diffusion and thereby an n<-> region of an N-channel part is formed. CONSTITUTION:On the occasion when an N-channel transistor is made to be LDD(Lightly-Doped-Drain), BF2 is ion-implanted in a P<+> region 9 and an oxide film being thicker than an n<+> region 14 is formed in the P<+> region by accelerated oxidation by F (fluorine) of the BF2. Thereafter the oxide film is removed only from the n<+> region 14, a side wall 10 doped with phosphorus is formed, annealing is executed so as to diffuse the phosphorus only in an N-channel part, and thereby an n<-> region 12 is formed. By this method, a photolithographic process for forming the n<-> region and a process of implantation of the phosphorus of n<-> can be curtailed and thus manufacturing processes can be shortened and simplified.
