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 plurality of chips each having two or more alignment holes for transmitting a laser beam are stacked. The laser beam is irradiated onto the uppermost or lowermost one of the stacked chips. A photodetector detects the laser beam output from the stacked chips through the alignment holes in these chips. The positions of the chips are so controlled that the amount of the light detected by this photodetector is a maximum.

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： A single crystal and a polycrystal having an excellent crystal quality and providing a highly reliable semiconductor device are formed by solid phase growth at low temperatures. An amorphous thin film is deposited on a substrate such that an average inter-atomic distance of main constituent element of the amorphous thin film is 1.02 times or more of an average inter-atomic distance of the elements in single crystal, and crystallization energy is applied to the amorphous thin film to perform solid phase growth to thereby form a single crystal. In another embodiment of the present invention, an amorphous semiconductor thin film is formed on a substrate or an insulating film such that an average inter-atomic distance distribution of main constituent element of the film substantially coincides with an average inter-atomic distance distribution of the element in a single crystal, and crystallization energy is applied to the amorphous semiconductor thin film to cause solid phase growth to thereby form a single crystalline semiconductor thin film.
