Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To resolve the problem of deterioration in breakdown voltage meeting the requirments for the time change rates in high frequency or voltage or current by providing a recess in a surface of a pressure-contact part on the semiconductor device side right over the element isolating region. SOLUTION: A plurality of semiconductor devices are integrated on the same substrate through the intermediary of an element isolating region 7 so as to self-contain a pressure-contact part using a terminal buffer plate 1 pressure welding these semiconductor devices. Next, a recess 3 is formed on the position right over the device isolating region 7 and the semiconductor device side of this self-contained thermal buffer plate 1. The depth of this recession 3 is decided to guarantee the dielectric strength exceeding the maximum voltage applied on the points A, B according to the dielectric constant of an insulating material interposed between the points A, B.  Through these procedures, the electric field strength of the title device is decreased so that the decline in the breakdown strength meeting the requirements for extremely high time change rates in the high-frequency or voltage or curreny may be hardly caused thereby enabling the reliability upon the device to be enhanced.
