Method of cleaning wafer and wafer with reduced impurities

A method of cleaning a wafer comprises: a scrubbing operation comprising treating a target wafer to be cleaned with a brush at a rotation rate of 200 rpm or less to prepare a brush cleaned wafer; and a cleaning operation comprising cleaning the brush cleaned wafer with a cleaning solution to prepare a cleaned bare wafer, wherein the cleaning operation comprises a first cleaning operation and a second cleaning operation sequentially.

PRE-CLEAN CHAMBER ASSEMBLY ARCHITECTURE FOR IMPROVED SERVICEABILITY

Apparatus for processing a substrate are described herein. More specifically, embodiments described herein relate to separate pre-clean process modules and pre-clean control modules coupled to a cluster tool assembly. Each pre-clean process module and each pre-clean control module are connected by a cable conduit which is configured to have power and control cables passing therethrough between the pre-clean process module and the ore-clean control module. A maintenance passage is formed through the cluster tool assembly. Each of a purge gas source, a process gas source, a manometer, an isolation port, and a throttle valve are all accessible from one side of the pre-clean process module.

20230135865 · 2023-05-04 ·

Provided are methods and systems for cleaning various semiconductor substrate storage articles, in particular, FOUP doors. The FOUP doors and other similar articles often have openings that may get contaminated with cleaning liquids if not covered. The described cleaning system includes contact points for engaging the article and covering these openings. The contact points may be also used for supporting the article and for pressurizing the openings in the article with a gas. The gas may be supplied through one or more contact points. It prevents liquids from getting into the openings if even the openings are not completely sealed. The pressurization may be maintained through the entire wet portion of the cleaning process. The article may be rotated within the cleaning system while cleaning and/or other liquids or gases are dispensed through a set of spraying nozzles. Spraying nozzles may move to enhance cleaning of the article.
