Abstract: The present disclosure generally relates to processing chamber seasoning layers having a graded composition. In one example, the seasoning layer is a boron-carbon-nitride (BCN) film. The BCN film may have a greater composition of boron at the base of the film. As the BCN film is deposited, the boron concentration may approach zero, while the relative carbon and nitrogen concentration increases. The BCN film may be deposited by initially co-flowing a boron precursor, a carbon precursor, and a nitrogen precursor. After a first period of time, the flow rate of the boron precursor may be reduced. As the flow rate of boron precursor is reduced, RF power may be applied to generate a plasma during deposition of the seasoning layer.

Abstract: Methods for modulating local stress and overlay error of one or more patterning films may include modulating a gas flow profile of gases introduced into a chamber body, flowing gases within the chamber body toward a substrate, rotating the substrate, and unifying a center-to-edge temperature profile of the substrate by controlling the substrate temperature with a dual zone heater. A chamber for depositing a film may include a chamber body comprising one or more processing regions. The chamber body may include a gas distribution assembly having a blocker plate for delivering gases into the one or more processing regions. The blocker plate may have a first region and a second region, and the first region and second region each may have a plurality of holes. The chamber body may have a dual zone heater.
