Abstract:
Methods of improving hot carrier parameters in a field-effect transistor by hydrogen reduction. A gate structure of the field-effect transistor is formed on a substrate, and the substrate is heated inside a deposition chamber to a given process temperature for a given time period. After the time period concludes, a conformal layer is deposited at the given process temperature over the gate structure, and is subsequently etched to form sidewall spacers on the gate structure. After the sidewall spacers are formed, a capping layer is conformally deposited over the gate structure and the sidewall spacers, and cured with an ultraviolet light treatment. An interconnect structure may be formed over the field-effect transistor and the capping layer, and a moisture barrier layer may be formed over the interconnect structure. The moisture barrier layer is composed of a material that is permeable to hydrogen and impermeable to water molecules.

Claim (Index 1):
A method comprising:\n forming a gate structure of a field-effect transistor on a substrate; heating the substrate inside a deposition chamber to a given process temperature for a hold time period of greater than or equal to 100 seconds; after the hold time period concludes, depositing a conformal layer of silicon nitride at the given process temperature over the gate structure; etching the conformal layer of silicon nitride to form a plurality of sidewall spacers on the gate structure; after the sidewall spacers are formed, depositing a first capping layer conformally over the gate structure and the sidewall spacers; and curing the first capping layer with a first ultraviolet light treatment, wherein the given process temperature is held constant during the hold time period, and the given process temperature is held constant during the deposition of the conformal layer of silicon nitride.
