Abstract

PURPOSE:To reduce a parasitic inductance and parasitic capacitance of a package of an element for a high frequency such as GaAsFET etc. by a method wherein a conductive layer arranged in a substrate on which an element is mounted and a metalization layer arranged in a concave part in the wall member are electrically connected with each other. CONSTITUTION:Wall member 2 is fixed around a ceramic substrate plate 1, a metallic lid 3 is brazed to a top surface of it and the element 13 is sealed in air-tight. On the upper surface of the substrate plate 1 are formed a source (grounding) metalization layer 10, a gate (input) metalization layer 8 and a drain (output) metalization layer 9 are formed on the upper surface of the substrate plate 1 such that they may be extended up to side surfaces thereof, and the lead terminals 5 and 4 are brazed to the side surfaces. The wall member 2 is made such that the metalization layer 22 is arranged at the inner surface having the ceramic material 20 provided with openings therein, thereafter the opening part 23 is stamped again in such a way as a part 11 of the metalization layer 22 is left in the concave part. Thereby, it is possible to provide such a structure as the source metalization layer 10 is connected to the lid 3, so that the parasitic effect caused by the container may be reduced and at the same time a disturbance of the parasitic effect may be eliminated.
