摘要:
A semiconductor device has recesses formed in the substrate during removal of the anti-reflective coating (ARC) because these recess locations are exposed during the etching of the ARC. Although the etchant is chosen to be selective between the ARC material and the substrate material, this selectivity is limited so that recesses do occur. A problem associated with the formation of these recesses is that the source/drains have further to diffuse to become overlapped with the gate. The result is that the transistors may have reduced current drive. The problem is avoided by waiting to perform the ARC removal until at least after formation of a sidewall spacer around the gate. The consequent recess formation thus occurs further from the gate, which results in reducing or eliminating the impediment this recess can cause to the source/drain diffusion that desirably extends to overlap with the gate.

An electronic device can include an insulating layer and a fin-type transistor structure. The fin-type structure can have a semiconductor fin and a gate electrode spaced apart from each other. A dielectric layer and a spacer structure can lie between the semiconductor fin and the gate electrode. The semiconductor fin can include channel region including a portion associated with a relatively higher VT lying between a portion associated with a relatively lower VT and the insulating layer. In one embodiment, the supply voltage is lower than the relatively higher VT of the channel region. A process for forming the electronic device is also disclosed.

摘要:
A transistor fabrication method includes forming an electrode overlying a channel of a semiconductor on insulator (SOI) substrate. Source/drain structures are formed in the substrate on either side of the channel. The source/drain structures include a layer of a second semiconductor over a first semiconductor. The first and second semiconductors have different bandgaps. The second semiconductor extends under the gate electrode. The source/drain structures may be formed by doping the source/drain regions and etching the doped regions selectively to form voids. A film of the second semiconductor is then grown epitaxially to fill the void. A film of the first semiconductor may be grown to line the void before growing the second semiconductor. Alternatively, the second semiconductor is a continuous layer that extends through the channel body. A capping layer of the first semiconductor may lie over the second semiconductor in this embodiment.
