Patent number: 11960730Abstract: Systems and methods described herein synchronize events between various components of storage device during the processing of an exception (i.e., an internal error). The storage device can have a plurality of processors which may each coordinate operations on various domains of storage device processing tasks. An exception occurring in one domain may require input and coordination from other domains within the storage device. Each exception may have a list of predetermined steps needed for completion which are coordinated via a series of sync points placed between exception action clusters which perform a series of specific operations until data or processing from another domain is needed to continue processing. The sync points can be utilized to halt processing in one domain until the other domains are in sync and complete one or more exception action operations. In this way, a streamlined and predictable synchronization between domains may occur during an exception.Type: GrantFiled: June 28, 2021Date of Patent: April 16, 2024Assignee: Western Digital Technologies, Inc.Inventors: Rishi Mukhopadhyay, Shiva K

Publication number: 20230386889Abstract: A susceptor for semiconductor substrate processing is disclosed herein. In some embodiments, the susceptor may comprise an inner susceptor portion and an outer susceptor portion. The susceptor portions may self-align via complementary features, such as tabs on the outer susceptor and recesses on the inner susceptor portion. The inner susceptor portion may contain several contact pads with which to support a wafer during semiconductor processing. In some embodiments, the contact pads are hemispherical to reduce contact area with the wafer, thereby reducing risk of backside damage. The inner susceptor portion may contain a cavity with which to receive a thermocouple. In some embodiments, the diameter of the cavity is greater than the diameter of the thermocouple such that the thermocouple does not contact the walls of the cavity during processing, thereby providing highly accurate temperature measurements.Type: ApplicationFiled: August 11, 2023Publication date: November 30, 2023Inventors: Saket Rathi, Shiva K.T.
