摘要： Herein disclosed is a semiconductor device of high density. The semiconductor device having a high density and a microstructure is required to have a high breakdown voltage and a high speed even with a low supply voltage. The semiconductor device comprises: a semiconductor body; a gate insulating film formed over the body; and a MOS transistor having a source/drain region formed in the body and a gate electrode film formed over the gate insulating film. The gate electrode film is composed of two or more films having different etching rates. The gate etching is stopped at the interface of the composite film to form an inverse-T gate electrode structure; and in that an electric conduction is observed between the component films. Thus, the overlap between the gate and the drain can be controlled.

摘要： A memory is disclosed which uses a microcapacitor as a data storage portion. The microcapacitor uses as its main electrode surface the side wall of a first trench formed on a semiconductor substrate, and is fabricated by diffusing an impurity from a second diffusion trench adjacent to the first trench by setting the shapes and diffusion conditions of the first and second trenches so that the tip of the diffusion layer reaches the side wall of the first trench. The capacitor uses the diffusion layer as one of the electrodes. An insulating film is deposited on the side wall of the first trench and an electrode as the other electrode of the capacitor is deposited on this insulating film. The memory can reduce a leakage current between memory cells by connecting the capacitor to a transistor fabricated in the same semiconductor substrate, and can be formed within a limited space.

摘要： An inspection method and apparatus for discriminating the foreign particles on the surface of a sample from the foreign particles or defects within the sample, and a semiconductor-device producing method using the inspection method and apparatus. The inspection apparatus includes a light source, a first optical system that causes the light from the source to be directed to the sample, a second optical system for condensing the light coming back from the sample, a polarizing prism for separating the condensed light into polarized components, and optical detectors, for detecting the polarized components. The two optical systems, are arranged for their optical axes to make an angle of 50.degree. to 120.degree. relative to each other. The foreign particles on the surface of the sample and the foreign particles or defects within the sample are respectively discriminated from each other as side scattered light and backward scattered light by utilizing the difference between the intensity ratios of the polarized light components.
