REDUCTION OF DIELECTRIC ISOLATION CAPACITANCE COUPLING

摘要

An intgrated semiconductor module is built in a single crystal silicon island and has the elements separated in the substrate by dielectric insulation. At least one part of the substrate has a low electrical resistance and an earth contact is connected to the low resistance zones. These zones are of the opposite type conductivity to that of the single crystal silicon island. This type of module reduces the capacitive coupling between the circuit elements in the high frequency wide band range. It is suitable for use in telecommunication systems in wide band applications eliminating the phenomenon of cross talk in the lines.
