  • Patent number: 12191205
    Abstract: A method includes forming a semiconductive channel layer on a substrate. A dummy gate is formed on the semiconductive channel layer. Gate spacers are formed on opposite sides of the dummy gate. The dummy gate is removed to form a gate trench between the gate spacers, resulting in the semiconductive channel layer exposed in the gate trench. A semiconductive protection layer is deposited in the gate trench and on the exposed semiconductive channel layer. A top portion of the semiconductive protection layer is oxidized to form an oxidation layer over a remaining portion of the semiconductive protection layer. The oxidation layer is annealed after the top portion of the semiconductive protection layer is oxidized. A gate structure is formed over the semiconductive protection layer and in the gate trench after the oxidation layer is annealed.
