Title: Manufacture of semiconductor device
Inventor: UENO SEIICHI
IPC: H01L21/60
Filed: 1986-04-15
Abstract: PURPOSE:To eliminate delicate control operations such as positioning a hook and adjustment of tensile force for cutting a fine metal wire and simplify and automate the operation by a method wherein an eutectic piece which forms an eutectic by the reaction with the fine metal wire for matching is contacted with the metal wire and the formed eutectic is absorbed by the eutectic piece to cut the metal wire. CONSTITUTION:An eutectic piece 4 for cutting is supported by an eutectic piece supporter 5 which has a heating means and is attached to the tip of the operation finger 8 of an automatic machine 7. The eutectic piece 4 is made of material which produces an eutectic with a fine metal wire 3 and made of Si in this case. When a part of the fine metal wire 3 is to be cut in order to achieve matching in a semiconductor device, the eutectic piece 4 is simply contacted with the fine metal wire 3. As the eutectic piece 4 made of Si is heated to at least 500 deg.C, when it is in contact with the fine metal wire 3 made of gold, the contacted part of the fine metal wire 3 is melted and a gold/silicon eutectic is formed and absorbed by the eutectic piece 4. Therefore, the fine metal wire 3 is cut at the melted part.

Abstract: PURPOSE: To efficiently improve soft foundation of hedoro or the like by stirring it with a sieve moving vertically, and injecting chemicals through the injection port provided on the sieve to mix them with the soft foundation.  
     CONSTITUTION: A float body 1 with pile means 2... and a sieve 4 drawn up is towed on the sea A to a working site by a tugboat. At the wirking site, the pile means 2... are lowered until they reach the foundation under a sludge layer B in order to prevent the movement of the float body 1, and with the state kept, the float body 1 is pushed up above the sea A. Then the sieve 4 is lowered to a proper position in the layer B, and fixed to the float body 1. Moving the float body 1 vertically along the pile means 2... causes the sieve 4 to move in the same manner, so that the layer B is stirred. At the same time, chemicals are injected from injection ports 8... provided on the sieve 4. This permits a wide range of weak subsoil to be stirred throughout the entire area, so that it can be efficiently improved.
