Abstract: An integrated circuit has a buried interconnect in the buried oxide layer connecting a body of a MOS transistor to a through-substrate via (TSV). The buried interconnect extends laterally past the TSV. The integrated circuit is formed by starting with a substrate, forming the buried oxide layer with the buried interconnect at a top surface of the substrate, and forming a semiconductor device layer over the buried oxide layer. The MOS transistor is formed in the semiconductor device layer so that the body makes an electrical connection to the buried interconnect. Subsequently, the TSV is formed through a bottom surface of the substrate so as to make an electrical connection to the buried interconnect in the buried oxide layer. A body of a transistor is electrically coupled to the TSV through the buried interconnect.
Abstract: The present invention generally relates to TFTs and methods for fabricating TFTs. For either back channel etch TFTs or for etch stop TFTs, multiple layers for the passivation layer or the etch stop layers permits a very dense capping layer to be formed over a less dense back channel protection layer. The capping layer can be sufficiently dense so that few pin holes are present and thus, hydrogen may not pass through to the semiconductor layer. As such, hydrogen containing precursors may be used for the capping layer deposition.
