Title: Underfill treating method for flip chip bonding and semiconductor device
Inventor: UEN-CHO VINCENT WANG
IPC: H01L21/56
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To enable use of various kinds of underfill materials by bonding a chip to solder connecting parts on a board after the solder connecting parts are individually sealed on the chip, when underfill treatment for flip-chip bonding the chip on the board is performed. SOLUTION: Sealed solder balls 205 on a chip 200 are first physically in contact with solder balls 305 on a board 300 which are not sealed. After the solder balls 305 are heated up to a reflow temperature, the solder balls 205 on the chip 200 are made to collectively flow with the solder balls 305 in order to perform common solder bonding. Sealing material 210 distributes again the stress from solder bonding to the whole part of the chip 200, and the fatigue life of solder bonding is prolonged. Solder bonding of the boundary side of the chip 200 is subjected to passivation treatment, so that various kinds of the sealing materials 210 can be used. As a result, the above practice mode has the same merit as a well-known underfill process, and sealing materials in a wider range can be used.
