  • Publication number: 20150079752
    Abstract: System and method for controlling the channel thickness and preventing variations due to formation of small features. An embodiment comprises a fin raised above the substrate and a capping layer is formed over the fin. The channel carriers are repelled from the heavily doped fin and confined within the capping layer. This forms a thin-channel that allows greater electrostatic control of the gate.
