Abstract:
1. A device platform, which contains at least one internal component, wherein the device platform is configured to isolate the at least one internal component from an environment external to the device platform while providing for electrical connectivity to at least one external component externally located on the outer surface of the said device platform, the device comprising: an enclosure, said enclosure including a top cover plate and a bottom substrate configured to define a sealed enclosure cavity for containing the at least one component, wherein said top cover plate is configured to allow reception and transmission of electromagnetic radiation, the surface of said top cover plate adjacent said enclosure cavity being covered with an epitaxial Si film in intimate cohesion, and wherein said bottom substrate is constructed of a high resistivity Si having a Si substrate material conductivity and includes at least one partial Si via (PSV), wherein said at least one partial Si via (PSV) is configured to electrically connect said at least one internal component with said at least one external component, and wherein said partial Si via (PSV) is formed by introducing a dopant with said Si material, wherein the combination of said dopant and said Si material results in at least one of a reduced conductivity and a conductivity that is opposite to that of said Si substrate material conductivity, and wherein an outer perimeter of each of said surface of said top cover plate adjacent said enclosure cavity and a surface of said bottom substrate adjacent said enclosure cavity includes a continuous gold fence cohesively bonded to its respective Si surface, wherein said top cover plate and said bottom substrate are configured such that said enclosure cavity is sealed using a gold-to-gold bond.
