Abstract:
Embodiments of the present invention provide methods and structures for protecting gates during epitaxial growth. An inner spacer of a first material is deposited adjacent a transistor gate. An outer spacer of a different material is deposited adjacent the inner spacer. Stressor cavities are formed adjacent the transistor gate. The inner spacer is recessed, forming a divot. The divot is filled with a material to protect the transistor gate. The stressor cavities are then filled. As the gate is safely protected, unwanted epitaxial growth (“mouse ears”) on the transistor gate is prevented.

Claim (Index 16):
A semiconductor structure, comprising:\n a semiconductor substrate; a first transistor gate and a second transistor gate disposed on the semiconductor substrate; a full inner spacer disposed adjacent to the first transistor gate; an outer spacer disposed adjacent to the full inner spacer; a lower inner spacer disposed adjacent to a lower portion of the second transistor gate; an upper inner spacer disposed adjacent to an upper portion of the second transistor gate and in contact with the lower inner spacer; and an outer spacer disposed adjacent to the lower inner spacer and upper inner spacer of the second transistor gate.
