Title: Semiconductor substrate
Inventor: MIURA MASAO
IPC: H01L21/02
Filed: 1990-01-18
Abstract: PURPOSE:To improve uniformity in etching and to prevent an effect of a clamp ring or the like on a region wherein a semiconductor device is made, by providing a region for various purposes around the region wherein the semiconductor device is made, in a semiconductor substrate which is used for making the semiconductor device. CONSTITUTION:A region 1 wherein a semiconductor device is made and a region 2 for various purposes are both formed as films on a semiconductor substrate. When a resist pattern is applied only on the region 1 and etching is executed, subsequently, the etching can be performed in the outer peripheral part of the region 1 without uneven distribution of plasma, since a material to be etched exists also in the region 2 in the outer peripheral part of the region 1. Accordingly, an etching rate is the same substantially in an area from the central part to the outer peripheral part in the region 1 and thus uniformity is improved. Besides, resist powder or the like produced by a pawl or a clamp ring in the region 2 is prevented from affecting the region 1.

Title: Radial taping electronic component
Inventor: NAKASE TAKEAKI
IPC: H05K13/00
Filed: 1990-01-18
Abstract: PURPOSE:To eliminate a need for a complicated component metal mold and to enhance the accuracy of the distance between taping terminals by a method wherein a metal wire material is bent to be nearly U-shaped and the taping terminals are connected. CONSTITUTION:An electronic component 11 is molded of an insulating material. A plurality of terminals 12 protrude from the board-mounting bottom face 11a. Holes 11b, 11c are made, by keeping a prescribed distance P, in positions other than protruding parts of the terminals 12 on the center line on the bottom face 11a. Taping terminals 13 are formed of a round metal wire material whose diameter is a little larger than the diameter of the holes 11b, 11c made in the bottom face 11a; the wire material is worked so as to have the same size as the distance P and to be U-shaped in such a way that mutual sides are parallel. Thereby, the distance P, of two sides at connecting ends 13a, 13b of the taping terminals 13, which must be accurate in the mounting operation is maintained highly accurately because the taping terminals are connected by the connecting ends 13a, 13b. A mounting accuracy can be enhanced.

Abstract: The invention relates to a method for autoclaving porous, lumpy materials by means of pressurised steam, the autoclaving process comprising, successively, a steam-operated heating phase, a holding phase and an expansion phase for pressure and temperature, the holding phase comprising a drying process in which the autoclave, going beyond compensating for heat losses and being set to a temperature above the evaporation temperature of the water, is heated indirectly and the material is dried by a controlled blowing-off of steam-containing heating medium from the interior of the autoclave. In order to obtain as dry a product as possible using as little energy as possible, it is provided that the drying process essentially extends over the entire holding phase, one or more autoclaves in the holding phase being supplied with sufficient heat for the steam necessary for a heating phase to be blown off and, after previous intermediate storage if appropriate, used to operate a heating phase. <IMAGE>
