Abstract:
1. A method for manufacturing a semiconductor mounting substrate, comprising: supplying solder onto connection lands provided on a substrate; mounting a semiconductor device and electronic components on the connection lands on the substrate, the semiconductor device having a silicon substrate and a resin layer provided on a face of the silicon substrate; heating the semiconductor device and the electronic components on the substrate so as to connect the semiconductor device and the electronic components onto the connection lands on the substrate by reflowing the solder; filling a first resin by injection into a space between the semiconductor device and the substrate from a central part of a side face of the semiconductor device; and hardening the first resin, wherein, after injection and filling of the first resin into at least the space, the first resin forms a bond strength reinforcing resin section between a side face in the vicinity of a corner part of the semiconductor device and a surface of the substrate in a position corresponding to the corner part, wherein the first resin of the bond strength reinforcing resin section covers an interface between the silicon substrate and the resin layer of the semiconductor device.
