Abstract: PROBLEM TO BE SOLVED: To facilitate installation in a fixture and have a structure hard to be detached after installation by providing a gasket having an engagement part constructed like a substantially inverted T-shape comprising an erect part and a hook part on the back of a main part, and forming a clearance groove in an intersecting interior angle part of the erect part and the hook part. SOLUTION: A gasket 1 for building comprises a domed hollow main part 2 and an engagement part 3. The engagement part 3 is so constructed that a hook part 3B is integrally attached to an erect part 3A integrally attached to the back of the main part 3 like a substantially inverted T-shape, and a clearance part 4 for facilitating bending of the hook part 3B is provided in an intersecting interior angle part of the erect part 3A and the hook part 3B. In the gasket 1 for building, when one side hook part 3B is inserted in an installation opening of a fixture 5 having a substantially C-shaped section, the tip of the other side hook part 3B is bent upward from the clearance groove 4 to easily fit the engagement part 3.  On the contrary, when we try to pull out the hook part 3B, the tip of the hook part 3B is warped from the clearance groove 4 part downward, so that resistance is increased to make it difficult to easily remove the hook part from a narrow installation opening. Thus, the gasket becomes hard to be detached.

Abstract: PURPOSE:To prevent the peeling of a photoresist film on a silicon nitride film by a double resist method. CONSTITUTION:A silicon substrate 11 having an N-type region 12 and a P-type region 13 is overlaid with a silicon oxide film 14 and a silicon nitride film 15 one after the other, and the silicon nitride film 15 is made rugged. This is overlaid with a first photoresist film 16, which is used as an etching mask to selectively remove silicon nitride film 15, resulting in a selective oxide mask of an insular silicon nitride film. The first photoresist film 16 is not ashed, but left as it is and used as a channel stop ion implantation mask for element isolation. A second resist film 17 which coats the whole face of either the N-type or P-type region is overlaid to prevent implantation of channel stop ions. The area of contact of the silicon nitride film 15 with the first photoresist film 16 increases; therefore, the resist film 16 overlaying the silicon nitride film 15 is prevented from peeling off.
