A thin circuit device that can operate at a high speed is provided. The circuit device includes a first circuit element and a circuit element portion formed on a substrate. The first circuit element and the circuit element portion are arranged in such a manner that element surfaces thereof are opposed to each other. A terminal formed on the element surface of the first circuit element and a terminal formed on the element surface of the circuit element portion are electrically connected to each other via conductive particles in a binder forming an anisotropic conductive film and a via. The anisotropic conductive film and a third insulating resin film are bonded by thermocompression bonding in the same step, thereby simplifying manufacturing steps of the circuit device.

An electrode for a semiconductor device is formed on the mounting surface (particularly, the outer periphery thereof) of a semiconductor substrate in a semiconductor module. In order to secure a large gap between the electrodes, an insulating layer is formed on the electrode. Also formed are a plurality of bumps penetrating the insulating layer and connected to the electrode, and a rewiring pattern integrally formed with the bumps. The rewiring pattern includes a bump area and a wiring area extending contiguously with the bump area.The insulating layer is formed to have a concave upper surface in an interval between the bumps, and the wiring area of the rewiring pattern is formed to fit that upper surface. The wiring area of the rewiring pattern is formed to be depressed toward the semiconductor substrate in relation to the bump area of the rewiring pattern.

In a heat radiation structure for an electronic appliance in which heat generated in a heat generating member inside a flap of the electronic appliance is radiated to a space outside the flap, a heat radiation plate integrally formed with a circuit element is thermally coupled to the heat generating member and is exposed outside the flap. Heat generated in the heat generating member is conducted to the heat radiation plate via a contact portion and is radiated to a space outside the flap from an exposed surface along with heat generated in the circuit element.
