Abstract: PURPOSE:To form an MOS transistor with a small occupied area and realize high integrity by forming the source and the drain of the transistor into vertical structures. CONSTITUTION:Trenches are formed in a semiconductor substrate 8 by anisotropic etching of Si. After an oxide film 3 and a nitride film 4 on it are laminated and patterned, channel cutting and field oxidation are carried out. After the oxide film and the nitride film are removed, channel doping is applied to trench walls by deposition and hot diffusion or by hot diffusion only to form a source 14 and a drain 15. After a foundation oxide film (-100Angstrom ) is laminated, doped polycrystalline silicon 31 for cell plate is deposited. Resist is applied and etching back is performed to the Si boundary and foundation 3 oxidation is carried out and a gate 9 is deposited. As the source and the drain of an MOS transistor formed by such processes are formed lengthwise long, the area of the transistor is small. Therefore, substantial improvement of the integration of a semiconductor device such as a semiconductor memory device in which MOS transistors occupy the most part of the area can be real ized.
