Abstract: PURPOSE:To enable the bonding of LSI without selecting the materials for a circuit board and a wiring of the circuit board by bonding the LSI chip to the board with a heat-seal agent including conductive particles such as Ag powder. CONSTITUTION:An Al pad 2 of the LSI chip 1 and a wiring 5 on a circuit board 6 are made to be electrically communicant with each other by Ag powder 8 in a heat-seal agent 7. For example, a wafer 9 including the pads 2 is coated with the heat-seal agent 7 on which the Ag powder 8 is dispersed uniformly. After that, the Ag powder 8 precipitates in the heat-seal agent 7. At this time, thickness of the heat-seal agent is 25mum and diameter of a particle of the Ag powder is 25mum and the dispersion distribution is 300 particles/mm. . After that, the part designated by the arrow is subjected to dicing and is then bonded to the wiring 5 on the circuit board 6. For the bonding, a soldering iron heated to 150 deg.C applys a pressure of 20kgr/cm for 5sec.
