ABSTRACT:
A ceramic substrate having a defined curvature and a method of its manufacture are described. For this purpose at least two ceramic layers having different defined temperature coefficients of expansion are positioned on top of one another and are permanently bonded together. A curved ceramic substrate may be advantageously utilized in micro-hybrid technology, in multilayer ceramic technology, or in hybrid technology, e.g., as a membrane element of a piezoresistive pressure sensor element.
