    摘要: A p-type silicon substrate has an element isolation region of an STI structure formed therein. A transistor region isolated by the isolation region has a n-type source/drain diffusion layer. Further, a p-channel impurity layer is formed substantially only in its channel region for controlling its threshold voltage (Vth). A gate insulator film consisting of a high dielectric film is formed on the channel region with an Si3N4 film interposed therebetween. A metal gate electrode having its bottom and side surfaces covered with the gate insulator film is provided in a self-alignment manner with respect to the source/drain diffusion layer.

    摘要: A method of filling one or more trenches formed in a silicon substrate includes the steps of forming a thin polycrystalline silicon film in a trench such that the thin polycrystalline silicon film is sufficiently thin so as to not close the trench; forming an amorphous silicon film on thin polycrystalline film and the surface of the substrate and in the trenches; and annealing the amorphous silicon film such that the amorphous silicon layer migrates to fill the trenches to a first level. The deposition and annealing steps are performed in ambient atmospheres having low partial pressures of H.sub.2 O and O.sub.2, the annealing temperature is higher than the deposition temperature, and the annealing pressure is greater than the deposition pressure.

    摘要: Inside a first cylinder for structuring an evaporator, a second cylinder is provided. The second cylinder has an undulated surface and a plurality of fine holes are provided on this surface. A liquid TEOS is contained in a first space positioned between the first cylinder and the second cylinder, and a second space positioned inside the second cylinder is filled with a gas TEOS evaporated from the fine holes. The pressure of the gas TEOS is set to be almost equal to the pressure of the liquid TEOS.
