摘要:
A package or mounting structure for hermetically sealing and supporting a microwave semiconductor device adapted for use with stripline transmission lines. A multilayer structure is assembled upon a conductive header, the elements of the multilayer structure having metallized surfaces thereon for providing contact to the microwave semiconductor device. The input and output leads to the mounting structure are adapted for use with strip transmission line configurations, the multilayer structure providing electrical and thermal conductive paths and including internal surface area for mounting microwave semiconductor devices and impedance matching components.

A semiconductor device comprises a substrate, a first semiconductor pellet mounted on the substrate, an insulating material washer mounted on the first pellet, and a second semiconductor pellet mounted on the washer. The second pellet is rigidly secured to the washer and the first pellet, and electrically connected to the first pellet, by means of a solder filling the washer central opening and bonded to both pellets.

A LAYER OF SOLDER IS PROVIDED ON A SURFACE PORTION OF A CARRIER. THE SOLDER LAYER IS THEN FORMED WITH A DEPRESSION WHOSE SIZE AND OUTLINE CORRESPOND TO THE SEMICONDUCTOR ELEMENT WHICH IS TO BE MOUNTED ON THE CARRIER, WHEREUPON THE SEMICONDUCTOR ELEMENT IS POSITIONED IN THE RECESS AND BONDED TO THE CARRIER BY SUBJECTING THE SOLDER TO REQUISITE THERMAL ENERGY.

FIRST AND SECOND ELECTRICAL CONNECTORS PASS THROUGH THE HOUSING OF A SEMICONDUCTOR DEVICE IN A GAS-TIGHT MANNER AND ARE ELECTRICALLY INSULATED FROM THE HOUSING AND FROM EACH OTHER. THE FIRST CONNECTOR IS IN ELECTRICAL CONTACT WITH AN ELECTRICALLY CONDUCTIVE BODY AND WITH A FIRST CONTACT ELECTRODE OF THE SEMICONDUCTOR DEVICE VIA THE CON-
DUCTIVE BODY, A PLURALITY OF SPRING DISCS AND A PRESSURE MEMBER. THE SECOND CONNECTOR IS IN ELECTRICAL CONTACT WITH THE CONTROL ELECTRODE OF THE SEMICONDUCTOR DEVICE.
摘要:
A transistor suitable for operation in the avalanche mode is connected in a switching circuit through coaxial lines. The outer conductors of the coaxial lines are electrically bonded to a base member and the center conductors of the coaxial lines are bored out to receive the ends of the transistor leads directly.
