Patent ID: 6924016

Claim:
An assembly system for stationing a semiconductor wafer for processing comprising: (a) a holding block made of a ceramic material selected from the group consisting of silicon carbide, zinc oxide, aluminum oxide, and titanium dioxide; (b) a semiconductor wafer; and (c) an aqueous adhesive composition interposed between the holding block and the semiconductor wafer, the adhesive composition comprising: water; at least one release agent selected from the group consisting of polyethylene glycols, fluorine-free surfactants selected from anionic, cationic, and nonionic surfactants, fluorine-containing surfactants selected from anionic, cationic and nonionic fluorosurfactants, and silicone polymers; and at least one water-soluble or water-dispersible resin selected from the group consisting of unsubstituted or substituted (meth)acrylic acid containing polymers, unsubstituted or substituted (meth)acrylate containing polymers, unsubstituted or substituted vinyl ester containing polymers, unsubstituted or substituted vinyl aromatic containing polymers, novolak resins, and polymers represented by the formula wherein each R 1 , R 2 , and R 3 independently is hydrogen or methyl; R is a hydrocarbyl group of 1 to 4 carbon atoms; each R 4 and R 5 independently is hydrogen or a hydrocarbyl group of 1 to 4 carbon atoms; R 6 is hydrocarbyl group of 1 to 20 carbon atoms; w, x, y, and z independently are a number from 1 to 100.
