Abstract:
A structure having isolated deep substrate vias with decreased pitch and increased aspect ratio is disclosed. The structure includes a device layer over a buried oxide layer, a deep trench extending through the device layer, a dielectric filler in the deep trench, via holes in the dielectric filler, and conductive fillers in the via holes being the isolated deep substrate vias. The dielectric filler may include silicon oxide. The conductive fillers may include tungsten or copper. An adjacent pair of the isolated deep substrate vias within the deep trench has a pitch equal to or less than 1.0 microns.

Claim (Index 1):
A structure comprising:\n a device layer over a buried oxide layer, wherein a field effect transistor (FET) is fabricated in the device layer, the FET including a source, a drain and a gate located at a first surface of the device layer, and wherein the buried oxide layer is located at a second surface of the device layer, opposite the first surface; a deep trench extending entirely through said device layer to said buried oxide layer; a dielectric filler in said deep trench; a via hole in said dielectric filler, said via hole extending through said dielectric filler and said buried oxide layer; and a conductive filler located in said via hole, wherein said conductive filler forms an isolated deep substrate via that extends through said dielectric filler and said buried oxide layer, wherein a portion of the conductive filler is exposed through the buried oxide layer at a bottom surface of the structure.
