Patent ID: 7098152

Claim:
A method of processing patterned semiconductor wafers comprising: applying on said wafers using a spin-on procedure a coating of a liquid adhesive composition comprising: (a) a dual polymer system, including i) from about 30 percent to about 50 percent by weight of a resin tackifier adhesive and ii) from about 5 percent to about 25 percent by weight of a thermoplastic polymer adhesive strengthening agent, (b) a dual solvent system for the polymers, comprising a relatively high boiling point and a relatively low boiling point solvent, (c) a nonionic surfactant; and (d) an ultraviolet (UV) dye detecting agent, curing said applied composition, mounting said wafer with cured coating onto a rigid substrate for thinning and backside processing of said wafer, and subsequently dissolving and removing said coating from the wafer.
