Abstract
An improved composite substrate comprises a patterned surface conductive layer of a refractory metal and a patterned compensation electrically conductive layer. The patterned compensation layer entirely overlies and extends beyond the shrunken patterned conductive layer. Additionally, thick film elements such as resistors are fabricated and contact selected areas of the patterned compensation conductive layer.
