| titleOfInvention |
Structure and method for gate-all-around metal-oxide-semiconductor devices with improved channel configurations |
| abstract |
The present disclosure provides an integrated circuit device comprising a semiconductor substrate having a top surface; a first source/drain feature and a second source/drain feature over the semiconductor substrate; semiconductor layers connecting the first source/drain feature and the second source/drain feature, the semiconductor layers stacked over each other along a first direction normal to the top surface; each of the semiconductor layers having a center portion of a first thickness and two end portions of a second thickness larger than the first thickness; each of the two end portions connecting the center portion and one of the first and the second source/drain features; a gate electrode engaging the center portion of each of the semiconductor layers; a first spacer over the two end portions of a topmost semiconductor layer of the semiconductor layers; and a second spacer between vertically adjacent end portions of the semiconductor layers. |
