Publication number: 20020096751Abstract: An integrated circuit structure having an adhesive agent for adhering to a substrate includes a first surface and a second surface opposite to the first surface. The first surface is formed with a plurality of bonding pads for electrically connecting to the substrate and transmitting signals from the integrated circuit to the substrate. An adhesive agent, which is non-adhesive at the room temperature, is applied onto the second surface. The adhesive agent becomes adhesive under pressing/heating so as to adhere onto the substrate. According to the structure, the problems caused by the overflowed glue can be avoided, the manufacturing processes can be facilitated, and the yield can be improved.Type: ApplicationFiled: January 24, 2001Publication date: July 25, 2002Inventors: Wen Chuan Chen, Kuo Feng Peng, C. H. Chou, Allis Chen, Nai Hua Yeh, Wu Hsiang Lee, Meng Ru Tsai, Hsiu Wen Tu, Jichen Wu
