SEMI E171 - Specification for Predictive Carrier Logistics (PCL)
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 September 2016; originally published September 2014; previously published February 2016.
The purpose of this Standard is to provide a communication scheme for exchanges of carrier logistics related information, especially predictive information, between equipment and the factory system in order to support seamless cascading of carriers for continuous processing of equipment in semiconductor fabrication systems or similar ones.
The purpose of this Standard is to provide models which represent carrier logistics management status in equipment to exchange predictive carrier logistics information in order to facilitate better synchronization with the factory system.
This Standard defines a model which represents logistics management of a carrier in equipment as Carrier Logistics Job (CLJ). CLJ includes the following functionalities.
- State management of logistics management of a carrier
- Prediction management including submission, resubmission and withdrawal upon a change of predicted information such as time or load port assignment
- Carrier ID assignment
- Load port assignment
This Standard defines a model which represents management of multiple CLJs in equipment as Carrier Flow Job (CFJ). CFJ includes the following functionalities.
- Order management of CLJs per process order
- Prediction management of CLJs per carrier logistics order
- Carrier scheduling
- Load port scheduling including a queuing of multiple CLJs on one load port
- Load port arbitration to CLJs for Internal Buffer Equipment
This Standard covers specifications for services to and events from CLJ and CFJ models.
This Standard covers PCL specifications for both Fixed Buffer Equipment and Internal Buffer Equipment.
This Standard covers compatibility with non-slot-integrity operation.
