Air cavity packages and methods for producing air cavity packages containing sintered bonded components, multipart window frames, and/or other unique structural features are disclosed. In one embodiment, a method for fabricating an air cavity package includes the step or process of forming a first metal particle-containing precursor layer between a base flange and a window frame positioned over the base flange.

Abstract:
A hermetically sealed integrated circuit package that includes a cavity housing a semiconductor die, whereby the cavity is pressurized during assembly and when formed. The invention prevents the stress on a package created when the package is subject to high temperatures at atmospheric pressure and then cooled from reducing the performance of the die at high voltages. By packaging a die at a high pressure, such as up to 50 PSIG, in an atmosphere with an inert gas, and providing a large pressure in the completed package, the dies are significantly less likely to arc at higher voltages, allowing the realization of single die packages operable up to at least 1200 volts. Moreover, the present invention is configured to employ brazed elements compatible with Silicon Carbide dies which can be processed at higher temperatures.
