    摘要: Multi-crystalline silicon processing techniques are provided. In one aspect, a method for roughening a multi-crystalline silicon surface is provided. The method includes the following steps. The multi-crystalline silicon surface is coated with a diblock copolymer. The diblock copolymer is annealed to form nanopores therein. The multi-crystalline silicon surface is etched through the nanopores in the diblock copolymer to roughen the multi-crystalline silicon surface. The diblock copolymer is removed. A multi-crystalline silicon substrate with a roughened surface having a plurality of peaks and troughs is also provided, wherein a distance from one peak to an adjacent peak on the roughened surface is from about 20 nm to about 400 nm.

    摘要: A method for forming a field effect transistor (FET) includes forming a dummy gate on a top semiconductor layer of a semiconductor on insulator substrate; forming source and drain regions in the top semiconductor layer, wherein the source and drain regions are located in the top semiconductor layer on either side of the dummy gate; forming a supporting material over the source and drain regions adjacent to the dummy gate; removing the dummy gate to form a gate opening, wherein a channel region of the top semiconductor layer is exposed through the gate opening; thinning the channel region of the top semiconductor layer through the gate opening; and forming gate spacers and a gate in the gate opening over the thinned channel region.
