IPC: D05B27/02
Filed: 1989-07-04
Abstract: PURPOSE:To make it easy to accurately guide a position of cloth to be sewn to a first egress-ingress way, by a method wherein a guide groove in which the position of the cloth to be sewed is dropped and guided to the first egress- ingress way, is provided along the direction in which the cloth is fed by a feed dog, ranging from the operator side to the first egress-ingress way. CONSTITUTION:On a throat plate 2, a guide groove 13 in which a position of cloth C to be sewn is dropped and guided to a first egress-ingress way 4, is provided along the direction in which the cloth is fed by a feed dog 9, ranging from a cut part 12 on the operator side to the first egress-ingress way, and the edge of the cut part 12 is so chamfered that the inner wall of part of the guide groove 13 is continuously extended toward the operator side. The guide groove 13 is so formed that an inclination theta2 for a second inner wall 13B on the cloth end side is larger than an inclination theta1 for a first inner wall 13A on the cloth main body side, and thus it is formed lest both the location of a needle 5 for the first egress-ingress way 4 and the position of cloth to be sewed relatively deviate in the right and left directions. In this way, sewing is kept acculate and in good result.

Title: Fabrication of semiconductor device
Inventor: OKANO JIYUNICHI
IPC: H01L21/3213
Filed: 1980-12-12
Abstract: PURPOSE:To increase an etching speed in fabrication of a semiconductor device and to make it possible to work with a lower output power and in a shorter time as well as to prevent overetching by a method wherein in the dry etching of B-doped polysilicon, the polysilicon layer is heat-treated before forming a resist mask. CONSTITUTION:For example, an SiO2 layer 22 is formed on an Si substrate 21 and selectively etched away to expose part of the surface of the substrate 21 to air. Next, after having deposited a B-doped polysilicon layer 23 all over the surface, it is heat treated at a high temperature for a certain period (for example, 1,000 deg.C, for 10min). Subsequently, a resist mask 24 is coated on the polysilicon layer 23 to create a pattern consisting of polysilicon layer 23 with a suitable technique, for example, plasma etching. With this process, because an etching speed of B-doped polysilicon can be larger, etching can be finished with a lower output power and in a shorter period than a conventional technique, so that overetching of polysilicon and etching of base layers (for example, in case of using an Si3N4 layer, etc.) can be prevented.
