    摘要: A low parasitic microwave transistor package is provided including a metal header formed from a base member and having a cylindrical center portion; a metallized ceramic insulator formed in an annular ring which is attached to the metal header and surrounding the center portion thereof. A shallow channel is provided in the surface of the pedestal or center portion of the metal header in which a metallized beryllia insulator is attached. Metal leads are attached to the ceramic insulator. The metallized beryllia insulator is suitable for a semiconductor die chip to be attached to the outward surface thereof such that any one of the preferred electrodes of the semiconductor chip can be attached to the header, by stitch bonding, through a very low inductance, low resistance connection. The other electrodes of a semiconductor chip may be selectively attached, via stitch bonds, directly to the metal leads or connected in series thereto through MOS capacitor chips which can be attached to the remaining surface area of the pedestal.

    摘要: A method of hermetically sealing flat pack containers having Kovar cans and covers which are gold plated on their sealing surfaces is described. The containers are first vacuum pretinned with an eutectic gold-tin solder so as to dissolve a constant amount of gold from the gold plated sealing surfaces. The containers and covers thus prepared are then juxtaposed at their sealing surfaces and fused together to hermetically seal the containers. Microelectronic devices are assembled within the container before the pretinned layers are fused together.
