  • Publication number: 20150270153
    Abstract: An apparatus for and a method of forming a semiconductor structure is provided. The apparatus includes a substrate holder that maintains a substrate such that the processing surface is curved, such as a convex or a concave shape. The substrate is held in place using point contacts, a plurality of continuous contacts extending partially around the substrate, and/or a continuous ring extending completely around the substrate. The processing may include, for example, forming source/drain regions, channel regions, silicides, stress memorization layers, or the like.

  • Publication number: 20080074922
    Abstract: A 2-transistor (2T) memory cell comprising a first transistor and a second transistor. The first and second transistors respectively have a source and a drain separated apart by a channel thereof, a floating gate over the channel near the source side, and a control gate over the floating gate and the channel near the drain side. The sources, floating gates, and control gates of the first and second transistors are respectively mutually connected. In addition, driving capability of the second transistor is substantially larger than that of the first transistor.
