Abstract:
1. A method for fabricating a hermetically sealable surface mount package, comprising: forming conductive patterns on a ceramic base, the conductive patterns comprising wire bond pads, input/output connections, a ground connection and at least one attachment pad for attachment of one or more microelectronic devices within the package; disposing a dielectric preform on an upper surface of the base, the preform having a thickness that is greater than a height of the one or more microelectronic devices, wherein the preform abuts portions of the wire bond pads and the input/output connections; disposing a seal ring on top of the preform; disposing a mold over the preform and seal ring to align the preform and seal ring with the base; firing the mold with the base, preform and seal ring under predetermined conditions to form a fused base, dielectric and seal ring, wherein the mold defines outer and inner dimensions of the dielectric; and removing the mold; wherein the dielectric defines a cavity within which the one or more microelectronic devices is retained.
