Exemplary support assemblies may include a top puck and a backing plate coupled with the top puck. The support assemblies may include a cooling plate coupled with the backing plate. The support assemblies may include a heater coupled between the cooling plate and the backing plate. The support assemblies may also include a back plate coupled with the backing plate about an exterior of the backing plate. The back plate may at least partially define a volume, and the heater and the cooling plate may be housed within the volume.

Multi-zone semiconductor substrate supports

Exemplary semiconductor processing systems may include a processing chamber, and may include a remote plasma unit coupled with the processing chamber. Exemplary systems may also include an adapter coupled with the remote plasma unit. The adapter may include a first end and a second end opposite the first end. The adapter may define a central channel through the adapter. The adapter may define an exit from a second channel at the second end, and the adapter may define an exit from a third channel at the second end. The central channel, the second channel, and the third channel may each be fluidly isolated from one another within the adapter.

Semiconductor processing chamber for multiple precursor flow

Embodiments of the present disclosure generally provide improved methods for processing substrates with improved process stability, increased mean wafers between clean, and/or improved within wafer uniformity. One embodiment provides a method for seasoning one or more chamber components in a process chamber. The method includes placing a dummy substrate in the process chamber, flowing a processing gas mixture to the process chamber to react with the dummy substrate and generate a byproduct on the dummy substrate, and annealing the dummy substrate to sublimate the byproduct while at least one purge conduit of the process chamber is closed.

Seasoning process for establishing a stable process and extending chamber uptime for semiconductor chip processing

Embodiments of the present technology may include a method of etching. The method may include mixing plasma effluents with a gas in a first section of a chamber to form a first mixture. The method may also include flowing the first mixture to a substrate in a second section of the chamber. The first section and the second section may include nickel plated material. The method may further include reacting the first mixture with the substrate to etch a first layer selectively over a second layer. In addition, the method may include forming a second mixture including products from reacting the first mixture with the substrate.

Process window widening using coated parts in plasma etch processes

A plasma source includes a first electrode and a second electrode having respective surfaces, and an insulator that is between and in contact with the electrodes. The electrode surfaces and the insulator surface substantially define a plasma cavity. The insulator surface defines one or more grooves configured to prevent deposition of material in a contiguous form on the insulator surface. A method of generating a plasma includes introducing one or more gases into a plasma cavity defined by a first electrode, a surface of an insulator that is in contact with the first electrode, and a second electrode that faces the first electrode. The insulator surface defines one or more grooves where portions of the insulator surface are not exposed to a central region of the cavity. The method further includes providing RF energy across the first and second electrodes to generate the plasma within the cavity.
