摘要: One or more embodiments described herein generally relate to selective deposition of substrates in semiconductor processes. In these embodiments, a precursor is delivered to a process region of a process chamber. A plasma is generated by delivering RF power to an electrode within a substrate support surface of a substrate support disposed in the process region of the process chamber. In embodiments described herein, delivering the RF power at a high power range, such as greater than 4.5 kW, advantageously leads to greater plasma coupling to the electrode, resulting in selective deposition to the substrate, eliminating deposition on other process chamber areas such as the process chamber side walls. As such, less process chamber cleans are necessary, leading to less time between depositions, increasing throughput and making the process more cost-effective.

摘要: Aspects of the present disclosure relate generally to pedestals, components thereof, and methods of using the same for substrate processing chambers. In one implementation, a pedestal for disposition in a substrate processing chamber includes a body. The body includes a support surface. The body also includes a stepped surface that protrudes upwards from the support surface. The stepped surface is disposed about the support surface to surround the support surface. The stepped surface defines an edge ring such that the edge ring is integrated with the pedestal to form the body that is monolithic. The pedestal also includes an electrode disposed in the body, and one or more heaters disposed in the body.

摘要: A plasma processing system is described. The system may include a showerhead. The system may further include a first RF generator in electrical communication with the showerhead. The first RF generator may be configured to deliver a first voltage at a first frequency to the showerhead. Additionally, the system may include a second RF generator in electrical communication with a pedestal. The second RF generator may be configured to deliver a second voltage at a second frequency to the pedestal. The second frequency may be less than the first frequency. The system may also include a terminator in electrical communication with the showerhead. The terminator may provide a path to ground for the second voltage. Methods of depositing material using the plasma processing system are described. A method of seasoning a chamber by depositing silicon oxide and silicon nitride on the wall of the chamber is also described.
