Abstract:
A method for forming a gaseous spacer in a semiconductor device and a semiconductor device including the gaseous spacer are disclosed. In an embodiment, the method may include forming a gate stack over a substrate, depositing a first gate spacer on sidewalls of the gate stack, epitaxially growing source/drain regions on opposite sides of the gate stack, and depositing a second gate spacer over the first gate spacer to form a gaseous spacer below the second gate spacer. The gaseous spacer may be disposed laterally between the source/drain regions and the gate stack.

Claim (Index 1):
A method comprising:\n forming a gate stack over a substrate; depositing a first gate spacer on sidewalls of the gate stack; epitaxially growing source/drain regions on opposite sides of the gate stack; depositing a second gate spacer over the first gate spacer to form a gaseous spacer below the second gate spacer, the gaseous spacer being disposed laterally between the source/drain regions and the gate stack; and after depositing the second gate spacer, planarizing the first gate spacer and the gate stack such that top surfaces of the first gate spacer and the gate stack are level with one another.
