SEMI E157 - Specification for Module Process Tracking
This Standard was technically approved by the Information & Control Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on May 11, 2016. Available at www.semiviews.org and www.semi.org in June 2016; originally published June 2010; previously published June 2011.
The purpose of this Specification is to define a standard equipment capability to report process-related data to the factory system. The subject of this Specification is the activities of a processing location (i.e., process module) that are related to the execution of a recipe.
The collection of process data during recipe execution is important to today’s semiconductor factories to support various applications that help optimize equipment processes, finished product quality, yield, and overall factory performance.
This process data reporting capability provides a factory’s applications the means of linking sampled time series data (Traces) and summary process data to related context data. Standard events that document recipe execution in the process module guarantee the availability of such context information. The context data may include such items as identification of process job, equipment recipe, and affected substrates. The reporting capability provides a record of start and/or end of processing, with granularity to the recipe step level.
Reporting of these events must be process module-specific to support the reporting of process module-specific data parameters. Each process module will typically have a different set of context and process data parameter values. A general event, one that applies to all process chambers, would report the same data, independent of which process module the current event report represents. Such general events do not support reporting of different data sets for each process module, as needed to capture the unique data parameters available from each.
This standard applies to data collection related to the portion of equipment recipe execution that directly affects the processing locations (process modules) within production equipment.
This standard addresses:
- Equipment recipe execution as it directly affects process modules
- Process module state model for recipe execution
- Event reporting for process data collection
- Process context data parameters
- Equipment recipe components and recipe steps contained in the recipe components as they apply to process modules
