Abstract: PURPOSE:To contrive the increase in speed, integration, and reliability of MOS transistors by a method wherein the gate insulation film of a MOS transistor is set to over a given resistivity determined by the allowable value of gate leakage current and under a larger resistivity than this given resistivity by two figures. CONSTITUTION:This divice is so constructed that the gate insulation film 4 of a MOS transistor is set to be over the given resistivity determined by the allowable value of gate leakage current and under a larger resistivity than this given resistivity by two figure. For example, as the gate insulation film 4 of a micro- sized MOS transistor, a tantalum oxide film with a resistivity of 10<11>-10<12>OMEGAcm is used. This tantalum oxide film 4 is formed on the substrate surface by sputter evaporation after formation of N<+> layers 3a, 3b. This manner can reduce the influence of hot electron phenomenon by preventing the variation in threshold voltage of the MOS transistor.

Water temperature at the normal temperature or 50 deg.C-80 deg.C is used. High-pressure water or high- pressure water heated is introduced to an injection nozzle 6 through a valve by a high-pressure hose 5. On the other hand, a selenium photosensitive body 8 is fixed, and given revolution. When high-pressure water is injected directly to the surface of the photosensitive body, water injected to the surface of the selenium film breaks the film surface first, one part to which said water is injected tis cracked by the energy of high-pressure water, high-pressure water permeates from a crack, and the selenium film is exfoliated from a base body. Exfoliation advances by making high-pressure water collide with a section between the base body and the selenium film.
