A type glue and method for mending chromium plate white defect by using the same

Abstract

The present invention relates to chromium plate repair sheets which comprises the following raw materials according to the parts by weight: 58-78wt% of a metal nano photoresistive material, 20-40wt% of a curing agent, 0.5%-2wt% of a diluent, and 0.1%-1wt% of a silica gel, the metal nano photoresistive material is any one of powdered gold, silver, nickel, tin or aluminum oxide, the curing agent is epoxy resin or phenolic resin, the diluent is any one of toluene, xylene, trimethylbenzene, turpentine or camphorated oil, and the glass promoter is silica gel. The invention further provides a method for repairing chromium plate white defects by the Chromium plate repair sheets. The provided Chromium plate repair sheets and the method for repairing the chromium plate white defects by the Chromium plate repair sheets solve the problems that printing ink can not repair dent and disconnection, and the chromium plate does not withstand cleaning by weakly alkaline cleaning liquids after being repaired by metal repair solutions, and the white defects caused by a glass substrate can not be repaired by CVD repair; and the glue guarantees the adhesive force of the repaired chromium plate.

Description

technical field [0001] The invention belongs to the technical field of chrome plate defect repairing, and in particular relates to a chrome plate repair adhesive and a method for repairing chrome plate white defects by using the chrome plate repair adhesive. Background technique [0002] The chrome plate is a kind of photomask, also known as a photomask, which is a pattern transfer tool used in the microelectronics manufacturing process. It is made of quartz glass or soda, and the pattern designed by the computer is exposed, Developing, etching and other processes are transferred to the light-blocking material on the surface of the chrome plate to form a new pattern, which is then used in the mass-replication production process of electronic parts. At present, white defects often occur in the production process of chrome plates. The white defects are also called pinhole defects in the industry. They refer to the influence of certain factors during the production and use of c...
