Abstract:
1. A method of attaching a thermally conductive film to an integrated circuit (IC) chip, comprising the steps of: positioning a thermally conductive film on a first side of a block; positioning an IC wafer on the film, wherein a non-active side of the wafer is in contact with the film, and wherein the IC wafer includes a plurality of chips; positioning a first surface of an elastomer pad in contact with an active side of the wafer, wherein the active side of the wafer is opposite the non-active side of the wafer; applying a predetermined pressure between a second side of the block that is opposite the first side and second surface of the elastomer pad that is opposite the first surface; and heating the film, the block, the wafer and the elastomer pad to a predetermined temperature for a predetermined time while the predetermined pressure is applied to bond the film to the wafer, wherein the film does not bond to the block.
