A top panel, which is disposed to face a module board with an electronic component therebetween, includes a resin layer and a metal layer, and has an insulating characteristic. The metal layer includes a metal layer formed at a front side of the resin layer and a metal layer formed at a rear side of the resin layer. With this structure, in reflow soldering performed in mounting a semiconductor module on a main board, warp which is caused, under temperature change, in the top panel due to difference in coefficient of thermal expansion between the resin layer and the metal layer formed at the front side of the resin layer is cancelled by warp which is caused, under temperature change, in the top panel due to difference in coefficient of thermal expansion between the resin layer and the metal layer formed at the rear side of the resin layer, whereby warp of the top panel is eliminated. This helps prevent the electronic component adhered to the top panel with adhesive from being pressed down to or pulled up from the module board due to warp of the top panel.

A substrate member is a manufacturing component of a module including electronic components mounted on a substrate and sealed with resin. The substrate member has substantially a plate-like shape and is to be the substrate later. A manufacturing process of the modules includes a mounting step of mounting electronic components on a component side of the substrate member, and a sealing step of supplying resin to flow on the component side so that the mounted electronic components are sealed with the resin. The mounting step includes mounting a first electronic component having substantially a flat mounting surface in a first mounting region specified on the component side so that a gap is formed between the mounting surface and the component side. The component side is provided with a first groove for boosting the resin to fill up the gap in the sealing step. Thus, insufficient filling of the resin in the gap between the substrate member and the electronic component is suppressed.

In a semiconductor device, an island penetrating hole, which is larger than a mounted chip, is formed on an island of a lead frame, and a heatsink is mounted on the island so as to cover the island penetrating hole. The chip is disposed on a surface of the heatsink in the island penetrating hole. The ground terminal of the chip and the island are wire-bonded to each other via GND wires. This arrangement makes it possible to reduce a heat resistance in a heat-releasing path, thereby improving a heat-releasing property. Further, the GND wires are shortened and a GND inductance is reduced. Consequently, it is possible to efficiently exert capability of the chip.
