    摘要： A first method of reducing semiconductor device substrate effects comprising the following steps. O+or O2+are selectively implanted into a silicon substrate to form a silicon-damaged silicon oxide region. One or more devices are formed over the silicon substrate proximate the silicon-damaged silicon oxide region within at least one upper dielectric layer. A passivation layer is formed over the at least one upper dielectric layer. The passivation layer and the at least one upper dielectric layer are patterned to form a trench exposing a portion of the silicon substrate over the silicon-damaged silicon oxide region. The silicon-damaged silicon oxide region is selectively etched to form a channel continuous and contiguous with the trench whereby the channel reduces the substrate effects of the one or more semiconductor devices. A second method of reducing substrate effects under analog devices includes forming an analog device on a SOI substrate and then selectively etching the silicon oxide layer of the SOI substrate to form a channel at least partially underlying the analog device.

    摘要： A new method is provided for the creation of a fuse. A layer of metal is first deposited, the layer of metal is patterned and etched creating a metal strip that is interrupted by a gap. The fusing function is created in the gap, the interrupted metal strip serves as the connectors to the fuse. A layer of conducting conjugated polymer is deposited over the metal strip and the therein created gap, the polymer is etched back leaving the deposited polymer in the gap between the two metal strips.
