摘要:
The present invention relates to a heat-resistant adhesive sheet (tape). More particularly, the invention relates to a heat-resistant adhesive sheet of high reliability and workability, in which crosslink reaction can be induced through irradiation of energy rays on an adhesive layer to achieve heat resistance at high temperature and also high dimension stability in parts, to achieve release without leaving any adhesive residues on an attached surface in releasing the layer and also to achieve no oxidation on the attached surface, e.g., a metallic surface at a high temperature. To this end, the heat-resistant adhesive sheet (tape) according to the invention is characterized by comprising a heat-resistant substrate, and an adhesive layer formed on at least one side of the heat-resistant substrate and made with a coating of liquid comprising energy ray curable olygomer resin, thermosetting adhesive resin, energy ray initiator and thermosetting agent, the adhesive layer being cured and heat resistant by irradiating energy rays to induce crosslink reaction.

This disclosure provides a method for laminating an adhesive tape and a lead frame, more specifically to reduce the warpage of a lead frame after heated lamination in which an adhesive tape for manufacturing semiconductor devices is attached to the lead frame, satisfying all the properties required for lamination, and avoiding adhesive residues from adhesive tapes and the leakage of a sealing resin. A method for laminating an adhesive tape and a lead frame comprises laminating an adhesive tape and a lead, wherein the lamination temperature of an adhesive tape surface and that of a lead frame surface are different from each other, for example, wherein the lamination temperature of the lead frame surface is lower than that of the adhesive tape surface by about 1 to about 200° C.

摘要:
Disclosed is a die bonding adhesive tape, which eliminates the requirement for additional adhesive tape for attaching a ring frame, decreases the curing time period upon die bonding, essentially prevents the transfer and diffusion of low-molecular-weight compounds between an adhesive film and an adhesive layer on a base substrate to thus exhibit excellent pick-up performance when picking up a die, and easily separates an adhesive film having a die from an adhesive layer on a base substrate when picking up slim and large dies. The die bonding adhesive tape of the invention includes a base substrate and an adhesive layer formed on the base substrate, has a structure in which a core film having a die bonding adhesive film attached thereto is bonded onto the adhesive layer, and enables direct die bonding via dicing and then die pick-up in a state of being mounted on a wafer.
