Abstract
Temperature gradients between a ceramic substrate of high thermal conductivity and the braze materials used to attach a metallic device such as a cap are reduced by using an embedded internal heat source in the substrate to minimize the thermal gradient, thereby minimizing the stresses that can result in substrate cracking when a cap is brazed onto the substrate.
