Patent JP-S63240077-A (JP)
Title: Semiconductor device
Inventor: TAKEDA EIJI
IPC: H01L23/12
Filed: 1987-03-27
Abstract: PURPOSE:To shorten the length of a bonding wire while obtaining matching in a wide band even at high frequency by incorporating a capacitance element into a transistor chip. CONSTITUTION:A space between an electrode section 1 for a field-effect transistor and a capacitance element 2 is narrowed by incorporating the capacitance element 2 into a field-effect transistor chip 3. Consequently, the length of a bonding wire can be reduced by half or less. Accordingly, the large change of phase is prevented by minimizing an inductance component even at high frequency, thus resulting in easy matching in a wider band even at high frequency.
