The invention relates to a device and a method for producing layers whose layer thickness distribution can be adjusted in coating systems with horizontally rotating substrate. A very homogeneous or a specific non-homogeneous distribution can be adjusted. The particle loading is also significantly reduced. The service life is significantly higher compared to other methods. Forming of parasitic coatings is reduced.

Methods and apparatus for processing a substrate are provided herein. For example, a processing chamber for processing a substrate comprises a sputtering target, a chamber wall at least partially defining an inner volume within the processing chamber and connected to ground, a power source comprising an RF power source, a process kit surrounding the sputtering target and a substrate support, an auto capacitor tuner (ACT) connected to ground and the sputtering target, and a controller configured to energize the cleaning gas disposed in the inner volume of the processing chamber to create the plasma and tune the sputtering target using the ACT to maintain a predetermined potential difference between the plasma in the inner volume and the process kit during the etch process to remove sputtering material from the process kit, wherein the predetermined potential difference is based on a resonant point of the ACT.

A sputtering device includes a substrate transferring unit which moves a substrate, a back plate disposed above the substrate transferring unit and supporting a target, and a magnet disposed on a second surface of the back plate which is opposite to a first surface of the back plate facing the substrate transferring unit, where the back plate includes a first portion and a second portion, which is bent from the first portion at a first angle.

A clamp ring including an inner periphery of increased diameter at locations where inwardly extending tabs are not located reduces the risk a workpiece that is placed in close proximity to the clamp ring or which contacts the clamp ring during processing will stick to the clamp ring.

A semiconductor process system includes a process chamber. The process chamber includes a wafer support configured to support a wafer. The system includes a bell jar configured to be positioned over the wafer during a semiconductor process. The interior surface of the bell jar is coated with a rough coating. The rough coating can include zirconium.

Disclosed are vapor transport deposition systems and methods for alternating sequential vapor transport deposition of multi-component perovskite thin-films. The systems include multiple vaporizing sources that are mechanically or digitally controlled for high throughput deposition. Alternating sequential deposition provides faster sequential deposition, and allows for reduced material degradation due to different vapor temperatures.

Embodiments disclosed herein generally provide improved control of gas flow in processing chambers. In at least one embodiment, a liner for a processing chamber includes an annular body having a sidewall and a vent formed in the annular body for exhausting gas from inside to outside the annular body. The vent comprises one or more vent holes disposed through the sidewall. The liner further includes an opening in the annular body for substrate loading and unloading.
