Patent ID: 6869822

Claim:
A method of making a semiconductor device comprising the steps of: bonding a semiconductor chip to a first substrate via first bumps; loading a sealing adhesive composition between the semiconductor chip and the first substrate to provide an adhesive sealing, the sealing adhesive composition containing at least a first main resin ingredient, a second main resin ingredient and a hardening agent, the sealing adhesive composition being capable of hardening in two stages; heating the adhesive sealing at a primary heating temperature for primary hardening; placing the first substrate on a second substrate with a second bumps interposed between the first substrate and the second substrate; and heating the adhesive sealing at a secondary heating temperature higher than the primary heating temperature for secondary hardening of the sealing adhesive composition due to hardening of the second main resin ingredient following preliminary softening of the adhesive sealing, while melting the second bumps for bonding the first substrate to the second substrate.
