Abstract
A ceramic multilayer wiring substrate is provided on which the metallized wirings are partially altered to provide multiple resistivities without changing the other electrical properties associated with a particular physical wiring geometry. Sequentially positioning conductive materials of different resistivities along the length of each individual wiring produces a final wiring pattern where each individual wiring can have a different resistance from the other wirings. A multiple resistivity wiring pattern can maximize the operation of a semiconductor chip attached thereto, for example, by reducing the effect of electronic noise on the semiconductor.
