    Abstract: An electronic device may include a substrate, a buried oxide (BOX) layer overlying the substrate, at least one semiconductor device overlying the BOX layer, and at least one STI region in the substrate and adjacent the at least one semiconductor device. The at least one STI region defines a sidewall surface with the substrate and may include a nitride layer lining a bottom portion of the sidewall surface, an oxide layer lining a top portion of the sidewall surface above the bottom portion, and an insulating material within the nitride and oxide layers.

    Abstract: Despite improvements in FinFETs and strained silicon devices, transistors continue to suffer performance degradation as device dimensions shrink. These include, in particular, leakage of charge between the semiconducting channel and the substrate. An isolated channel FinFET device prevents channel-to-substrate leakage by inserting an insulating layer between the channel (fin) and the substrate. The insulating layer isolates the fin from the substrate both physically and electrically. To form the isolated FinFET device, an array of bi-layer fins can be grown epitaxially from the silicon surface, between nitride columns that provide localized insulation between adjacent fins. Then, the lower fin layer can be removed, while leaving the upper fin layer, thus yielding an interdigitated array of nitride columns and semiconducting fins suspended above the silicon surface. A resulting gap underneath the upper fin layer can then be filled in with oxide to isolate the array of fin channels from the substrate.
