<p>PROBLEM TO BE SOLVED: To provide with a small number of item parts a field-effect transistor(FET) which has superior electrical characteristics. SOLUTION: An insulation ceramic part 12 is extended toward a FET chip 15, a metalized open stub 17 is formed on its top surface and a capacitance component is added. The stub 17 is preferably divided into plural parts and they are selectively interconnected by a bonding wire 18. Consequently, it is possible to get an inexpensive FET that has a superior electrical characteristic with a small number of item parts and to adjust a capacitance component by correcting manufacturing dispersion as necessary.</p> |
