Assignee: RAYTHEON COMPANY
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An electrical device comprising:
a substrate;
a temperature-sensitive material supported by the substrate, the temperature-sensitive material having a thermal degradation temperature in a range from 50° C. to 250° C.; and
(i) a stress buffer layer supported by the substrate and formable at a temperature less than the thermal degradation temperature of the temperature-sensitive material such that the stress buffer layer is configured to minimize strain at an interface of the temperature-sensitive material; and/or (ii) a stress compensation layer supported by the substrate and formable at a temperature less than the thermal degradation temperature of the temperature-sensitive material such that the stress compensation layer is configured to counteract forces imparted to the substrate to thereby control an amount of substrate bow;
wherein the electrical device includes both the stress compensation layer and the stress buffer layer, which are both aluminum nitride (AlNx) layers.
