Abstract

PURPOSE:To form a contact section, in which the coatability of a metallic wiring is improved, by selectively boring an inter-multilayer insulating film on a substrate, shaping an etching protective film, in which the sidewall of an opening section is coated with a semiconductor material nonreactive to a melting solution for an silicon oxide film, and removing a natural oxide film in the bottom of the opening section. CONSTITUTION:An N-type diffusion layer 2 is formed to a P-type silicon sub strate, and inter-layer insulating films 3 and 4 as a lower layer and an upper layer are laminated onto the top face of the layer 2. An ion implantation method such as arsenic (As) one is used for shaping the N-type diffusion layer 2. A contact hole 6 is bored onto the N-type diffusion layer 2 through patterning by a photoetching method and plasma etching in the inter-layer insulating films 3 and 4, and a polycrystalline silicon film 8 is grown on the whole surface of the substrate including the inside of the hole. The polycrystalline silicon film 8 is etched back by employing an anisotropic plasma etching method, and the polycrystalline silicon film 8 is left only on the sidewall surface of the contact hole 6. A removal process to a natural oxide film 7 is executed before an aluminum wiring 5 is sputtered.
