Abstract:
Semiconductor devices and fabrication methods are provided. A fabrication method includes: forming a source and drain material layer over a substrate; forming a mask layer over the source and drain material layer and including a first trench exposing a portion of the source and drain material layer; forming a protective layer on sidewalls of the first trench; forming a second trench in the source and drain material layer using the mask layer and the protective layer as an etch mask; removing the protective layer after the second trench is formed; forming a channel material layer and a gate structure on the channel material layer after the protective layer is removed; and removing the mask layer after the channel material layer and the gate structure are formed. The channel material layer is on the sidewalls and the bottom of the first trench and the second trench.

Claim (Index 17):
A semiconductor device, comprising:\n a substrate; a source and drain material layer formed on the substrate, wherein the source and drain material layer contains a first trench there-through; a mask layer formed on the source and drain material layer containing a second trench there-through, wherein the second trench has a cross-section area larger than the first trench and covers the first trench; a channel material layer conformally formed on a bottom and sidewalls of each of the first trench and the second trench; and a gate structure conformally formed on the channel material layer, on the bottom and the sidewalls of each of the first trench and the second trench.
