Abstract

Accurate clock synchronization and time stamping plays a significant role in ensuring data quality as the semiconductor industry faces an imminent data explosion with the deployment of Interface A. Standards and Guidelines significantly ease the deployment of factory-wide distributed system synchronization where many pieces of equipment and applications from a variety of vendors exist. The SEMI Time Synchronization Working Group identified the industry?s critical timing requirements and addressed the challenges by developing new standards and guidelines while ensuring legacy standards can adopt the new standard and maintain backwards compatibility. This presentation provides insight to the motivations and key concepts for a time synchronization standard and reports on experiences doing evaluations of Interface A implementations. These experiences highlight additional insights possible with Interface A, including the internal sensor data value refresh rate. Interface A provides finer data collection granularity, more visibility into the data, and a window into the industry?s data quality issues.
