Patent number: 11621149Abstract: Disclosed are a corrosion-resistant gas delivery assembly and a plasma processing apparatus. An inlet gas delivery component and a gas diffusion component are combined correspondingly with an inlet gas accommodation hole and a diffusion accommodation space that are arranged in a liner body, to form a multi-component structural configuration, which avoids direct contact of the process gas with the liner body due to liner body surface defects caused by high temperature. The advantages as offered include: effectively preventing the process gas from corroding a gas delivery assembly and the plasma processing apparatus, and solving the problems such as metal contamination and solid particle contamination in the reaction chamber caused by the corrosive fraction in the process gas; besides, the multi-component structural configuration facilitates routine maintenance.Type: GrantFiled: October 23, 2020Date of Patent: April 4, 2023Assignee: ADVANCED MICRO-FABRICATION EQUIPMENT INC.

Patent number: 11348763Abstract: Disclosed is a corrosion-resistant structure for a gas delivery system in a plasma processing apparatus. By providing a plating layer of corrosion-resistant material at the parts including the gas channel to avoid reacting with the delivered corrosive gas, metal and particle contaminations are reduced. By reversely mounting nozzles such that they reliably cover the plating layer inside the gas outlet holes, the disclosure prevents the corrosion-resistant material from being damaged by the plasma generated inside the cavity. By forming a corrosion-resistant yttrium oxide coating at the surfaces of the nozzles exposed to the cavity, the disclosure prevents the plasma from eroding the nozzles. The disclosure further leverages a flexible corrosion-resistant material, such as Teflon, to the sealing surfaces of the liner in contact with the dielectric window and the cavity, which improves the overall sealing effect of the liner.Type: GrantFiled: May 28, 2020Date of Patent: May 31, 2022Assignee: ADVANCED MICRO-FABRICATION EQUIPMENT INC.
