ADHESIVE TAPE FOR MANUFACTURING ELECTRIC COMPONENTS

Title:

ADHESIVE TAPE FOR MANUFACTURING ELECTRIC COMPONENTS

Document Type and Number:

WIPO Patent Application WO/2010/101324

Kind Code:

A1

Abstract:

The present invention relates to an adhesive tape for manufacturing electric components. More specifically, the adhesive layer is not adhesive at room temperature, but adhesion is expressed only during a thermal lamination process, thus enabling lamination on a lead frame. The adhesive tape has a partial interpenetration reticular structure caused by additional photocuring of the adhesive layer. Thus, the adhesive tape has improved thermal resistance with regard to thermal history in which the adhesive tape is exposed during the manufacturing process of a semiconductor apparatus. The adhesive tape improves apparatus reliability during manufacture of a semiconductor apparatus and prevents leakage of encapsulation materials. The adhesive tape also prevents transfer of adhesives to the lead frame or encapsulating material when removing the tape after the processes are finished. To this end, the adhesive tape for manufacturing electric components contains a thermally resistant substrate and the adhesive layer to which an adhesive composition is applied on the thermal resistant substrate. The adhesive composition contains phenoxy resin, thermal curing agent, energy ray-curable acryl resin, and photoinitiator. The adhesive layer is cured by thermal curing and energy rays.
