Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: a step (A) which is a step of preparing one or more combinations of n semiconductor components and n resin layers, and one substrate, a first bonding step (B) of bonding said substrate and said first semiconductor component through said first resin layer in a semi-cured state, by laminating at least one first resin layer and at least one first semiconductor component in this order, on the substrate, to form at least one laminated structure, followed by heating at a temperature at which the resin layer is semi-cured and which is lower than a temperature at which the solder layer melts; a repetitive bonding step (C) of obtaining, on the substrate, at least one laminate in which (n−1) resin layers and (n−1) semiconductor components are laminated alternately, by repeating a process until the n−1th semiconductor component is bonded, in which another resin layer and another semiconductor component are laminated in this order on said semiconductor component which is bonded, followed by heating at a temperature which is lower than a temperature at which the solder layer melts, to bond the semiconductor component through said resin layer in a semi-cured state, with the proviso that this step is omitted when n equals 2; a step (D) of preparing a pair of clamping members, and, on one clamping member, mounting said substrate on which at least one laminate is laminated, with the proviso that this step is omitted in those cases where said substrate is already mounted on a pair of clamping members in a step prior to this; a step (E) of obtaining, on the substrate, at least one laminate in which n resin layers and n semiconductor components are laminated alternately, by further laminating the nth resin layer and the nth semiconductor component in this order on said n−1th semiconductor component in said laminate which is mounted on the clamping member; a clamping and soldering step (F) of obtaining a structure which is a soldered laminate, by clamping said substrate and said laminate from a substrate side and a side of said nth semiconductor component with said one clamping member and the other clamping member, and also by heating said substrate and laminate at a temperature equal to or higher than a temperature at which the solder layer melts, to carry out soldering between connection terminals that are facing each other; and a curing step (G) of heating at a temperature which is equal to or higher than a curing temperature of the resin layer, to thereby promote curing of said first to nth resin layers.
