Abstract:
1. A method of production of a semiconductor device package, comprising a circuit board provided inside it with a capacitor, said method comprising: forming connection pads on one surface of a metal plate, with one surface of the connection pads being in close contact with said one surface of the metal plate, directly connecting external connection terminals of a capacitor to the other surface of the connection pads, forming a circuit board provided with a conductor circuit electrically connecting said connection pads and said external connection terminals of the capacitor at said one surface of said metal plate, thereby embedding said capacitor in said circuit board, and etching the other surface of said metal plate to expose a semiconductor mounting surface of the circuit board, including at least said one surface of the connection pads to be directly connected to electrode terminals of a semiconductor chip.
