Abstract:
A process for mounting a semiconductor device by using an anisotropic conductive adhesive film, which process comprising:the step of tentatively thermocompression bonding a conductive particle-free filmy insulating adhesive onto a wiring board to thereby form an insulating adhesive layer; the step of forming a concave in said insulating adhesive layer by using a press head provided with a pressing chip of a predetermined size; the step of putting in the concave of said insulating adhesive layer an anisotropic conductive adhesive film having conductive particles dispersed in an insulating adhesive; and the step of mounting the semiconductor device having a predetermined electrode at a predetermined position of a compression bonding head and then positioning said semiconductor device and thermocompression bonding to thereby electrically connect the electrode of said semiconductor device to the electrode of said wiring board.
