Filed: 1988-09-28
Abstract: PURPOSE:To relax stress generated in the bonded area and to prevent occur rence of cracking of sintered material in brazing a metallic lead frame to a sintered AlN by previously bonding a copper foil to the side of a face of the metallic lead frame to be brazed. CONSTITUTION:Molybdenum-manganese plate is attached to the surface of a sintered aluminum nitride 1 by screen printing, calcined and then a metallizing layer 2 is formed by application of nickel plating. On the other hand, a copper foil 4 is previously bonded to the side of a face of a metallic lead frame 3 (e.g., lead frame made of Kovar) to be brazed to the sintered aluminum nitride 1. Then the sintered aluminum nitride 1 is brazed to the metallic lead frame 3 by using a brazing agent 5 (e.g., silver braze). Consequently, the sintered AlN can be brazed to the metallic lead frame and a semiconductor package using AlN having excellent thermal conductivity can be done.

IPC: H01L23/06
Filed: 1989-09-20
Abstract: PURPOSE:To enable a high frequency semiconductor device to be finely adjusted in high frequency characteristic and corrected in deviation of characteristic caused by the bonding of a cap to a case by a method wherein a metallized part is not formed on the whole rear of the cap but formed into a certain pattern so as to be capable of adjusting a magnetic coupling between the cap and a micro-strip circuit. CONSTITUTION:An optional conductor pattern is selectively formed on the rear of a high frequency case cap, whereby magnetic coupling between the cap and inner circuit is varied in degree. That is, a metallized part 7 is not provided to the whole rear of the cap 20 but a metallized pattern 20 is partially provided to the cap 20. Therefore, the cap 20 is not so much deteriorated in magnetic shielding effect and can be decreased in magnetic coupling with a micro-strip circuit. By this setup, the deviation of a semiconductor device in characteristics caused by the sealing with the cap 20 can be corrected. A mutual coupling between the input side and the output side of the micro-strip circuit can be cut off by a partitioning plate, a shielded space can be made substantially small, and the upper limit of an operating frequency can be set.
