The adhesive in the adhesive layer is curable with an energy beam and the so cured adhesive develops tackiness again when heated. When the tape is used in processing a semiconductor wafer, it serves as a dicing tape for holding the wafer in position during the dicing step. Each piece of the diced and cured adhesive layer, that is attached to each chip and capable of being tackified by heating, provides an adhesive required for securely mounting the chip on the lead frame in the die-bonding step.Type: GrantFiled: February 21, 1992Date of Patent: October 18, 1994Assignee: Lintec CorporationInventors: Mikio Komiyama, Yasunao Miyazawa, Kazuyoshi Ebe, Takanori Saito

Patent number: 5252669Abstract: A water reducible resin for use in a coating composition is produced by grafting in organic solvent a thermoplastic polymer onto a thermosetting polymer that has been copolymerized with acid group-containing monomers to render the resultant polymer water soluble. Thermoplastic polymer is also grafted onto a phosphatized polyepoxide for the sake of adhesion of a coating to a substrate. A film formed from a waterborne coating composition containing the grafted polymers as a binder has both the toughness properties characteristic of a thermoplastic and the flexibility properties of a thermosetting resin.Type: GrantFiled: December 19, 1991Date of Patent: October 12, 1993Assignee: PPG Industries, Inc.Inventors: Rudolf Maska, Marvin T. Tetenbaum, James R. Bodwell, David C. Kapp

Patent number: 5204386Abstract: A thixoropic adhesive composition exhibiing good sag resistance is prepared comprising a mixture of a polymer-modified epoxy resin and a rheological control agent. The polymer-modified epoxy resin is preferably a dispersion of acrylic elastomer in an epoxy resin in which the acrylic elastomer particles have added hydroxyl functionality which interacts favorably with rheological control agents, such as fumed silica. Acrylic epoxy resin dispersions containing added hydroxyl functionality give improved rheological control.Type: GrantFiled: June 9, 1992Date of Patent: April 20, 1993Assignee: The Dow Chemical CompanyInventors: Yasemin Ersun-Hallsby, Dwight K. Hoffman, Gerald C. Kolb, Gene D. Rose
