Adhesive for semiconductor device, and high productivity method for manufacturing said device
Disclosed is a method for manufacturing a semiconductor device which includes: a semiconductor chip; a substrate and/or another semiconductor chip; and an adhesive layer interposed therebetween. This method comprises the steps of: heating and pressuring a laminate having: the semiconductor chip; the substrate; the another semiconductor chip or a semiconductor wafer; and the adhesive layer by interposing the laminate with pressing members for temporary press-bonding to thereby temporarily press-bond the substrate and the another semiconductor chip or the semiconductor wafer to the semiconductor chip; and heating and pressuring the laminate by interposing the laminate with pressing members for main press-bonding, which are separately prepared from the pressing members for temporary press-bonding, to thereby electrically connect a connection portion of the semiconductor chip and a connection portion of the substrate or the another semiconductor chip.
