Abstract: The present disclosure relates to exclusion rings for use in processing a semiconductor substrate in a processing chamber, such as a chemical vapor deposition chamber. The exclusion ring includes an alignment structure that cooperates with an alignment structure on a platen on which the exclusion ring will rest during processing of the wafer. The first alignment structure includes a guiding surface which promotes the reception of and positioning of the second alignment structure within the first alignment structure. Methods of utilizing the described exclusion rings are also described.
