Title: Manufacture of laminated wafer
Inventor: NAITO SHINJI
IPC: H01L21/02
Filed: 1992-02-10
Abstract: PURPOSE:To obtain a robust laminated semiconductor wafer wherein cracks are not generated on the surface when mirror surface polishing process is performed by applying large load. CONSTITUTION:The surface of a semiconductor wafer 110 on the side where a semiconductor element is formed, out of two laminated semiconductor wafers 110, 120, is polished to obtain a specified thickness. From the polished semiconductor wafer 110 toward the other semiconductor wafer 120, sloping down taper type beveling is performed on the whole of outer peripheral part 101 of the laminated semiconductor wafer 100, thereby obtaining a lamination semiconductor wafer wherein a taper part is formed on the outer peripheral part. After that, the surface of a semiconductor wafer 110 on the side where a semiconductor element is to be formed is subjected to mirror polishing. The radius of the semiconductor wafer wherein the taper part is formed does not become small, and the shape is hard to generate cracks. Thereby cracks or the like are not generated when mirror surface polishing or the like is performed.

Abstract: PURPOSE:To easily manufacture a sintered coil by a method wherein slurry-like raw material, which is formed by mixing microscopic metal particles, or microscopic metal particles and ceramic microscopic particles, a high molecular substance and water and/or an organic solvent, is extrusion-molded, it is wound up on a bobbin and then sintered in the state wherein the state of winding is being maintained. CONSTITUTION:A slurry-like material is formed by mixing, while an extrusion-molding process is being conducted, a high molecular substance which works as a binder and water and/or an organic solvent which works as a fluidizing agent into the mixture of microscopic metal particle or the mixture of microscopic metal particles and microscopic ceramic particles. After the surface of a bobbin has been sprinkled with powder, the above-mentioned material is wound up on the spool while it is being linearly molded by an extrusion-molding device. The adhesive property of the surface of the extrusion-molding material, which is in a non-dried adhesive state, is removed by adhering the above-mentioned powder thereon, and the adhesion of the adjacent loops is prevented when they are brought into contact with each other. When the extrusion- molded material is dried up and sintered in the state wherein the constraint from the inside of the bobbin is removed, a coil-like sintered body can be obtained. As a result, a sintered coil can be manufactured easily.
