Abstract: PURPOSE: To provide a manufacturing method wherein firstly defects or pollution matter are not introduced into a channel part, and secondly the shape of grooves is formed uniformly, in the manufacture of MOSFET which has a channel part at the side of a groove. CONSTITUTION: An n-type epitaxial layer 2 in low impurity concentration is made on the side of one main face of an n<+> -type semiconductor substrate 1, and with this face as the main surface, the specified region is chemically dry- etched. The region including the face produced by the chemical dry etching is selectively oxidized to form a selective oxide film with a specified thickness. Then, p-type and n-type impurities are diffused doubly from the main surface, whereby the length of a channel is regulated and at the same time, a base layer and a source layer are made. Furthermore, an n<+> -type semiconductor substrate 1 is made a drain layer. After this double diffusion, a gate electrode is made through a gate oxide film, and source and drain electrodes are made.

Abstract: PURPOSE:To obtain an inexpensive optical scanner by machining a specular surface to form machining streaks in parallel or inclination to an optical scanning line so that beams of zero order and diffracted beams of higher order do not scan superposedly on the optical scanning line. CONSTITUTION:A reflection surface 2 is so machined that the machining streaks 2' thereof intersect orthogonally with a revolving shaft 8 so that the array of diffracted beams 6' and 7' of higher order intersect orthogonally with a scanning line 4. The line 4 of a scanning beam 5 and the beams 6', 7' scan in parallel apart at a certain space between each other but do not scan superposedly. A shielding plate is provided if the superposed harmful scanning arises by having a time lag on the scanning line of the beam 5 owing to the presence of the diffracted beams of higher order. The plate 9 is provided with an aperture of a fine slit 10 for allowing the passage of only the main scanning beam 5 to shut off the diffracted beams of higher order. The machining streaks are thus allowed to a certain extent and the stage of manufacture is simplified.
