US Patent 10326002 Self-aligned gate contact and cross-coupling contact formation

Methods of forming self-aligned gate contacts and cross-coupling contacts for field-effect transistors and structures for field effect-transistors that include self-aligned gate contacts and cross-coupling contacts. A sidewall spacer is formed at a sidewall of a gate structure and an epitaxial semiconductor layer is formed adjacent to the sidewall spacer. After forming the epitaxial semiconductor layer, the sidewall spacer is recessed with a first etching process. After recessing the spacer, the gate structure is recessed with a second etching process. After recessing the gate structure, a cross-coupling contact is formed that connects the gate structure with the epitaxial semiconductor layer.
