IPC: C07C67/00
Filed: 1978-04-04
Abstract: PURPOSE: To an aqueous solution of pyruvate salt resulting from the catalytic oxidation of hydroxyacetone is added isopropyl alcohol to crystallize out the pyruvate salt, which is separated by filtration, thus producing high-purity pyruvate salt.  
     CONSTITUTION: Hydroxyacetone in an aqueous solution is oxidized with an oxygen- containing gas in the presence of a catalyst to form pyruvic acid, to which an alkali substance is gradually added to obtain a pyruvate salt. After separation of the catalyst from the aqueous solution, isopropyl alcohol is added to crystallize out the pyruvate salt, which is simultaneously removed from the by-product, acetate salt, thus giving high-purity pyruvate salt. The amount of isopropyl alcohol used is 2W 10, preferably 4W6 parts by volume per one part of the aqueous solution. As isopropyl alcohol fairly dissolves acetate salts, the use of isopropyl alcohol permits simultaneous separation of acetate salt.

Title: Semiconductor storage device, manufacture thereof and protective sheet used therefor
Inventor: YAMASHITA MASAYUKI
IPC: H01L27/10
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To contrive the enhancement of the reliability, specially the moisture resistance, of a semiconductor storage device, by a method wherein a protective film for a substrate is constituted of a resin film, which is made to bond on a bonding agent and is cut off from a protective sheet formed into a structure, wherein at least a base tape and the resin film are laminated. SOLUTION: A bonding agent 6 is cured and thereafter, a protective sheet is peeled off from the bonding agent 6. The adhesive strength of the bonding agent 6 is selected so that the adhesive strength is stronger than the shearing strength of a resin film and the adhesive strength of the resin film to a base tape. In the case where the protective sheet is peeled off, the resin film 7 on the bonding agent 6 receives a strong shearing stress on the periphery of the bonding agent 6 and is cut in the part of this periphery. Moreover, the adhesive strength of the film 7 to a buffer film 8 is weaker than the adhesive strength of the bonding agent 6 to the film 7, and the film 8 is peeled off from the film 7. As a result, the film 7 is left only on the bonding agent 6 and the film 7 can be used as a protective film with a sealed opening part.  As a result, penetration of a contaminated material and water from a redundant fuse part within the open part provided in the substrate protective film into a substrate is prevented and the enhancement of the reliability, specially the moisture resisance, of a semiconductor storage device is contrived.
