  • Patent number: 6391744
    Abstract: A method of thinning a non-SOI device using an SOI thinning process that includes the steps of receiving an SOI starting wafer, where the SOI starting wafer includes a silicon substrate and an oxide layer thereon; selecting a non-SOI fabrication process for fabricating the non-SOI device; forming a layer of device quality silicon on the oxide layer of the SOI starting wafer to a sufficient thickness and doping profile to realize the non-SOI device; fabricating the non-SOI device in the device quality silicon layer using the non-SOI fabrication process selected; forming a support layer on the device quality silicon layer having the non-SOI device fabricated therein; and thinning the result of the last step using the SOI thinning process.
