    Abstract: Embodiments of the present disclosure generally relate to hardmasks and to processes for forming hardmasks by plasma-enhanced chemical vapor deposition (PECVD). In an embodiment, a process for forming a hardmask layer on a substrate is provided. The process includes introducing a substrate to a processing volume of a PECVD chamber, the substrate on a substrate support, the substrate support comprising an electrostatic chuck, and flowing a process gas into the processing volume within the PECVD chamber, the process gas comprising a carbon-containing gas. The process further includes forming, under plasma conditions, an energized process gas from the process gas in the processing volume, electrostatically chucking the substrate to the substrate support, depositing a first carbon-containing layer on the substrate while electrostatically chucking the substrate, and forming the hardmask layer by depositing a second carbon-containing layer on the substrate.

    Abstract: Method for depositing amorphous silicon materials are provide and include generating a plasma within a plasma unit in fluid communication with a process chamber and flowing the plasma through an ion suppressor to produce an activated fluid containing reactive species and neutral species. The activated fluid either contains no ions or contains a lower concentration of ions than the plasma. The method further includes flowing the activated fluid into a first inlet of a dual channel showerhead within the process chamber and flowing a silicon precursor into a second inlet of the dual channel showerhead. Thereafter, the method includes flowing a mixture of the activated fluid and the silicon precursor out of the dual channel showerhead and forming an amorphous silicon layer on a substrate disposed in the process chamber.

    Abstract: In one implementation, a method of forming an amorphous silicon layer on a substrate in a processing chamber is provided. The method comprises depositing a predetermined thickness of a sacrificial dielectric layer over a substrate. The method further comprises forming patterned features on the substrate by removing portions of the sacrificial dielectric layer to expose an upper surface of the substrate. The method further comprises performing a plasma treatment to the patterned features. The method further comprises depositing an amorphous silicon layer on the patterned features and the exposed upper surface of the substrate. The method further comprises selectively removing the amorphous silicon layer from an upper surface of the patterned features and the upper surface of the substrate using an anisotropic etching process to provide the patterned features filled within sidewall spacers formed from the amorphous silicon layer.

    Abstract: A system for processing a substrate is provided including a first planar motor, a substrate carrier, a first processing chamber, and a first lift. The first planar motor includes a first arrangement of coils disposed along a first horizontal direction, a top surface parallel to the first horizontal direction, a first side, a second side. The substrate carrier has a substrate supporting surface parallel to the first horizontal direction. The first processing chamber has an opening to receive a substrate disposed on the substrate carrier. The first lift includes a second planar motor having a second arrangement of coils disposed along the first horizontal direction. A top surface top surface of the second planar motor is parallel to the first horizontal direction. The first lift is configured to move the top surface of the second planar motor between a first vertical location and a second vertical location.
