Abstract
PURPOSE: To reduce an operation Q and obtain a stable operation over a wide range by raising a nominal impedance of a chip with a matching circuit with a monolithic construction in a transistor chip.
CONSTITUTION: A collector, emitter and base layer are provided in a semiconductor chip 5 to make an electrode as a pattern a. A base electrode 22 is arranged to surround an emitter electrode 21 and a bond butt 8a and 8b are prepared. An insulation layer 27 is provided thereon, a hole for passing through the layer 27 is provided in a position 24a, it is connected to a second electrode 23 and is connected through a third electrode 25 and insulation layer 28 in a position 23b. Successively, an electrode butt 6 is prepared. The third electrode 25 is connected at the connection point 25 to the butt 6. A capacitance is made by the butt 6 and 8b and the electrode 23 and 25 serve as an inductance. The chip 5 with such a construction is mounted on a package with an internal matching circuit. Therefore, an impedance matching capacitance 10 can be formed in a small size, whereby the input impedance is raised and a stable operation can be obtained over a wide range.
