Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To obtain an alkanol amide of high purity with reduced content of amid esters by reaction of an fatty acid ester with an alkanolamine in the presence of an alkali catalyst. SOLUTION: A fatty acid ester of formula I (R<1> is a 7-12C alkyl or alkenyl; R<2> is a 1-3C alkyl) and an alkanolamine of the formula: Hm N-(R<3> -OH)n (R<3> is a 1-5C alkylene; m and n are each 1 or 2 where m+n=3) are allowed to react with each other to give an alkanol amide of formula II. On the reaction, an alkali catalyst is used in such an amount that satisfies the following formula: 0<[A-(w+AV)]<=1 in mmol/g (A is the amount of the alkali catalyst; w is the water content of the reactants; AV is the acid value of the reactants, both of which are based on 1g of the reactant, respectively) such as sodium methylate and the reaction conditions are at 70-150 deg.C and 10-400Torr for 1-6 hours. It is undesirable that side-reactions occurs, when the amount of the catalyst is less than the described one, while an excessive one causes discoloration.

Title: Formation of bump
Inventor: NISHIMORI TAKASHI
IPC: H01L21/60
Filed: 1990-11-14
Abstract: PURPOSE:To efficiently remove air bubbles generated during a plating operation to the outside of a tank by a method wherein the bump formation face of an object to be plated is set facedown, a plating liquid is spouted out to and brought into contact with the bump formation face through a mesh-shaped anode electrode faced with it, the electrode is turned simultaneously and a bump is formed on the bump formation face. CONSTITUTION:An object 3, to be plated, in which Cr or Cu is sputtered onto a silicon wafer 12 and to which a resist has been applied and arranged uniformly is set facedown while it is being supported by cathode pins 2 situated at the upper part of a plating tank 1. A PbSn plating liquid is spouted out to and brought into contact with the bump formation face of the specimen 3 through a mesh-shaped anode electrode 4 arranged and fixed so as to be faced with it; at the same time, the mesh-shaped anode electrode 4 is turned and a wet plating operation is performed. By the flow of the plating liquid which has been caused by its turning operation, air bubbles generated during a plating operation are removed from the object to be treated. The air bubbles are then removed to the outside of the plating liquid by the flow of the plating liquid which is spouted from the bottom part of the plating tank. Even when the flow rate of the plating liquid is not large, the air bubbles can be removed from the object to be removed. As a result, the shape of a bump formed on the object to be treated can be made to be straight and an irregularity in its height can be reduced.

IPC: B24B37/00
Filed: 1991-10-25
Abstract: PURPOSE:To prevent breakage and damage of a wafer by separating upper and lower fixing boards in a water or the other liquid bath at the time of collecting a polished wafer. CONSTITUTION:A wafer 5 held by a carrier 4 is clamped by upper and lower surface plates 1, 2 under suitable pressure, and while an abrasive liquid is supplied from an abrasive liquid supply port 8, the surface plates 1, 2 are relatively rotated. After the completion of polishing, the rotation of the surface plates 1, 2 is stopped, and enough quantity of water 12 to force the upper and lower surface plates 1, 2 which still clamp the wafer 5 to sink is supplied in a pan 11. After the water is supplied into the pan 11, the upper and lower surface plates 1, 2 are lowered to be sunk in the water 12, and when the water 12 enough permeates into a polishing area between the surface plates 1, 2, the lower surface plate 1 is a little lowered to be sunk. At this time, the wafer 5 follows the lower surface plate 1 and sinks together with the carrier 4. The abrasive liquid remaining in a water bath is diluted by the water 12 to weaken the surface tension. Subsequently, after the surface plate 2 is raised largely, the lower surface plate 1 is raised to let the wafer 5 escape upward from the bath of water 12 to be collected.
