Abstract:
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.

Claim (Index 1):
A method for manufacturing a semiconductor device including a semiconductor chip, a substrate and/or another semiconductor chip, and an adhesive layer interposed therebetween, the semiconductor chip, the substrate, and the another semiconductor chip each having a connection portion having a surface formed by a metal material, the connection portion of the semiconductor chip and the connection portion of the substrate and/or the another semiconductor chip being electrically connected by metal bonding, the method sequentially comprising the following steps of:\n heating and pressuring a laminate having: the semiconductor chip; the substrate, the another semiconductor chip or a semiconductor wafer including a portion corresponding to the another semiconductor chip; and the adhesive layer disposed therebetween, the connection portion of the semiconductor chip and the connection portion of the substrate or the another semiconductor chip being disposed to face each other, by interposing the laminate with a pair of facing 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 a pair of facing pressing members for main press-bonding, which is separately prepared from the pressing members for temporary press-bonding, to thereby electrically connect the connection portion of the semiconductor chip and the connection portion of the substrate or the another semiconductor chip by metal bonding, wherein at least one of the pair of pressing members for temporary press-bonding is heated to a temperature lower than a melting point of the metal material forming the surface of the connection portion of the semiconductor chip and a melting point of the metal material forming the surface of the connection portion of the substrate or the another semiconductor chip when the laminate is heated and pressured, and at least one of the pair of pressing members for main press-bonding is heated to a temperature equal to or higher than at least one melting point of a melting point of the metal material forming the surface of the connection portion of the semiconductor chip, or a melting point of the metal material forming the surface of the connection portion of the substrate or the another semiconductor chip when the laminate is heated and pressured.
