Abstract:
1. A micropackage comprising: a semiconductor wafer having at least one isolated portion, each isolated portion being electrically isolated from the rest of the wafer by air gaps or trenches; a thin support layer or film of insulating material formed on the wafer for supporting the isolated portion, the support layer being substantially planar in a lateral direction and being at least partially defined by a single wafer, the support layer or film having at least one hole extending completely therethrough, wherein each hole is generally aligned with at least a portion of one of the respective isolated portions; and electrically conductive material formed in each hole and electrically connected to each isolated portion of the wafer, wherein each isolated portion is supported by a supporting portion of the thin layer or film, the conductive material and the isolated portion of the wafer forming a substantially vertical feedthrough extending through the wafer for signal transfer through the wafer and the thin layer or film and through the micropackage.
