Patent number: 7968195Abstract: The invention provides an adhesive sheet which can be stuck to a wafer at low temperatures of 100° C. or below, which is soft to the extent that it can be handled at room temperature, and which can be cut simultaneously with a wafer under usual cutting conditions; a dicing tape integrated type adhesive sheet formed by lamination of the adhesive sheet and a dicing tape; and a method of producing a semiconductor device using them. In order to achieve this object, the invention is characterized by specifying the breaking strength, breaking elongation, and elastic modulus of the adhesive sheet in particular numerical ranges.Type: GrantFiled: July 17, 2008Date of Patent: June 28, 2011Assignee: Hitachi Chemical Co., Ltd.Inventors: Teiichi Inada, Michio Mashino, Michio Uruno
