Abstract
A transistor includes a first gate electrode, a first capping layer, a crystalline semiconductor oxide layer, a second capping layer, a first gate dielectric layer, and source/drain contacts. The first capping layer, the crystalline semiconductor oxide layer, and the second capping layer are sequentially disposed over the first gate electrode. Sidewalls of the second capping layer are aligned with sidewalls of the crystalline semiconductor oxide layer. The first gate dielectric layer is located between the first gate electrode and the first capping layer. The source/drain contacts are disposed on the second capping layer. The crystalline semiconductor oxide layer and the source/drain contacts are located on two opposite sides of the second capping layer.
