Capacitor-equipped semiconductor device

A capacitor-equipped semiconductor device comprising:

• a semiconductor chip having a plurality of electrode terminals;
• a sheet-like substrate having at least a film capacitor;
• a mounting substrate provided on one side thereof with chip connection terminals disposed to correspond to the electrode terminals of the semiconductor chip and a ground terminal disposed to correspond to one electrode terminal of the film capacitor of the sheet-like substrate, the mounting substrate being provided on an other surface thereof with an external connection terminal connected to the chip connection terminals and the ground terminal and used to mount the mounting substrate on an external substrate, wherein
• the sheet-like substrate is interposed between the semiconductor chip and the mounting substrate;
• the electrode terminals of the semiconductor chip are connected to the chip connection terminals;
• and
• the one electrode terminal of the film capacitor is connected to the ground terminal, and an other electrode terminal is connected to a predetermined electrode terminal of the electrode terminals of the semiconductor chip.
