Leistungstransistorzelle

摘要

The invention concerns power transistor cells consisting of a configuration of separate transistors provided with contact fingers whereon is placed an air bridge (1) with thermal and electric conductivity. Said bridge has a dimension which, in the longitudinal direction of the contact fingers, considerably exceeds the length of said contact fingers, such that on the side of a row of contact fingers, parts of the air bridge can be placed on metal surface connections or on the substrate surface by means of conductive contact pillars (8), thereby resulting in a good heat dissipation of the isolated transistors.
