Abstract:
1. A transistor comprising: a substrate; a channel in the substrate; a source and drain on opposing sides of the channel in the substrate; source and drain contacts connected to the source and drain; a gate dielectric layer over the substrate; a gate electrode separated by the gate dielectric layer from the channel; a spacer between said gate electrode and said source and drain contacts; and wherein a portion of at least one of said source contact and said drain contact overlies said gate electrode, wherein said portion of said at least one of said source contact and said drain contact is isolated from said gate electrode by an insulator which is only between said gate electrode and said portion of said at least one of said source contact and said drain contact, wherein the entire insulator is laterally confined to within said gate electrode by said spacer, and wherein said insulator is an oxide of said gate electrode.
