Patent ID: 8545663

Claim:
In a process for manufacturing a semiconductor device comprising heating a wiring board on which a chip and an uncured adhesive layer are laminated for curing the adhesive layer, the improvement comprising performing the following steps: applying a dicing/die-bonding sheet to a wafer and dicing the wafer and an uncured adhesive layer in order to prepare chips; releasing the chips from a base film of the dicing/die-bonding sheet at an interface between the base film and the uncured adhesive layer, and mounting the released chips on the wiring board; a statically pressurizing step before the adhesive layer is cured in the following heat curing step, in which step the wiring board on which the chip and the uncured adhesive layer are laminated is subjected to a static pressure greater than atmospheric pressure by 0.05 to 1.0 MPa, in which step a temperature of an atmosphere surrounding the semiconductor device is controlled to be in the range of about 30° C. to about 120° C. while avoiding a curing of the adhesive layer, and in which step the pressure is directly and uniformly applied to the wiring board in all directions without using a bag-shaped object formed of a flexible material and a flexible sheet, the uncured adhesive layer being a single adhesive layer formed from a liquid adhesive or a single adhesive layer formed from a film adhesive; and a heat curing step comprising curing the uncured adhesive layer of the wiring board by heating the wiring board on which the chip and the uncured adhesive layer are laminated under the application of static pressure, wherein the statically pressurizing step and the heat curing step are terminated at the same time.
