Multilayer substrate for semiconductor chip esp. integrated circuit - with conducting zones sepd. by insulating layers

摘要

Semiconductor device has a multilayer substrate with semiconducting and electrically conducting zone(s) and insulating layer(s). A semiconductor chip, esp. an integrated circuit, is placed on this substrate and has electrical connections to the conducting zone. Mass prodn. of these substrates with controlled high reliability is possible by conventional methods of mfr.
