Abstract

Transistors with self-aligned source/drain regions and methods for making the same. The methods include forming a gate structure embedded in a recess in a substrate; removing substrate material around the gate structure to create self-aligned source and drain recesses; forming a channel layer over the gate structure and the source and drain recesses; and forming source and drain contacts in the source and drain recesses. The source and drain contacts extend above the channel layer.
