Abstract: Processing methods comprising selectively replacing a first pillar material with a second pillar material in a self-aligned process are described. The first pillar material may be grown orthogonally to the substrate surface and replaced with a second pillar material to leave a substantially similar shape and alignment as the first pillar material.

Abstract: Implementations of the present disclosure generally relate to the fabrication of integrated circuits. More particularly, the implementations described herein provide techniques for deposition of boron-carbon films on a substrate. In one implementation, a method of processing a substrate is provided. The method comprises flowing a hydrocarbon-containing gas mixture into a processing volume of a processing chamber having a substrate positioned therein, wherein the substrate is heated to a substrate temperature from about 400 degrees Celsius to about 700 degrees Celsius, flowing a boron-containing gas mixture into the processing volume and generating an RF plasma in the processing volume to deposit a boron-carbon film on the heated substrate, wherein the boron-carbon film has an elastic modulus of from about 200 to about 400 GPa and a stress from about −100 MPa to about 100 MPa.

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.

Abstract: Processing methods to create self-aligned contacts are described. A conformal liner can be deposited in a feature in a substrate surface leaving a gap between the walls of the liner. A tungsten film can be deposited in the gap of the liner and volumetrically expanded. The expanded film can be removed and replaced with a contact material to a make a contact. In some embodiments, a conformal tungsten film can be formed in the feature leaving a gap between the walls. A dielectric can be deposited in the gap and the conformal tungsten film can be volumetrically expanded to grow two pillars. The pillars can be removed and replaced with a contact material to make two contacts.
