Abstract:
1. A thin flat semiconductor package comprising a semiconductor die having first and second power electrodes on its respective opposite first and second surfaces; first insulation plate having first and second conductive layers on its respective opposite surfaces which are insulated from one another; second insulation plate having a plurality of spaced first conductive layers on a first surface thereof and a second conductive layer on an opposite second surface thereof; said first and second power electrodes of said die being electrically and mechanically fixed to said first conductive layer on said first insulation plate and to one of said first conductive layers on said second insulation plate to define a sandwich of said first and second insulation plates with said die between them; and at least first and second lead conductors each electrically connected to a respective first conductive layer on said first surface of said second insulation plate and extending beyond the peripheral edge of said sandwich, whereby the second conductive layers of the first and second insulation plates are both exposed for cooling said die, wherein said first conductive layer of said first insulation plate has a flat central portion for receiving said die and a raised peripheral region, said second power electrode being electrically and mechanically connected to said flat central portion, and said raised peripheral region being electrically and mechanically connected to one of said first conductive layers on said first surface of said second insulation plate.
