ABSTRACT:
An electronic device package is provided, consisting of reaction bonded silicon nitride structural and dielectric components and conductor, resistor, and capacitor elements positioned with the package structural components. The package consists of a ceramic package base characterized by a dielectric constant less than 6, of reaction bonded silicon nitride, or a heat spreader material. An electrical conductor is positioned on, embedded in, or attached to the package base for making electrical contact to an electronic device supported on the base and in preferred embodiments, a resistor is attached to the package base. The invention also provides package sidewalls connected to the package base, preferably of reaction bonded silicon nitride, and at least one electrical conductor extending to an outside surface of the package sidewalls for making electrical contact to an electronic device supported by the package base. The reaction formed electronic device packages of the invention provide the ability to support high device signal frequencies, high device operational temperatures, and high environmental temperatures, due to the characteristics of the package materials. The reaction formed electronic device packages of the invention may be produced with a nitriding process during which the overall package structure exhibits minimal shrinkage. As a result, the reaction formed electronic device packages of the invention may be shaped to finished dimensions before the nitriding process with complicated and tight-tolerance geometries of package structural, conducting, resistive, and capacitive components.
