Abstract

This standard was technically approved by the global Information & Control Committee. This edition was approved for publication by the global Audits & Reviews Subcommittee on April 25, 2007. It was available at www.semi.org in June 2007. Originally published July 2002; previously published July 2006.

 

E This standard was editorially modified in September 2007 to correct an error. Changes were made to Table R1-13.

 

This document provides specification for implementing basic equipment performance tracking for production equipment. Provisions in this document enable the host computer to track basic equipment performance in an automated and consistent matter, without operator or host input. This document provides specification for equipment suppliers to: Track basic equipment states (no operator or host input required); Track basic equipment states in a modular manner, for both major modules and the overall equipment; Report basic equipment state changes to a host computer, at both module and equipment level; Report equipment’s time in state to a host computer, at both module and equipment level; Report reasons to a host computer for why equipment is blocked from performing its task, at both module and equipment level. Equipment users require the ability to track equipment performance without dependence on user input to eliminate inaccuracies due to incorrect or untimely input from the user. The ability to track equipment performance without user input is essential in 300 mm wafer factories where operational scenarios require minimal manual interaction. EPT defines concepts, behavior, and message services that enable the host computer to obtain the equipment data required for equipment performance tracking in an automated and consistent matter without operator or host input. EPT enables factory managers to identify the current states of factory equipment, both at the equipment level and at the module level (e.g., processing chambers), without dependence on user input. EPT enables factory engineers to evaluate the time that equipment and modules spent in different states and identify areas for improvement. EPT enables factory engineers to obtain directly from the equipment the reasons why the equipment or module is prevented from performing. EPT provides industrial engineers the equipment data which, when combined with external data from the manufacturing execution system (MES), will enable accurate calculation of SEMI E10 states and SEMI E79 metrics at the equipment-level and the module-level. EPT enables automation engineers to develop reusable host interfaces by using a standardized collection event and data variables to collect equipment state data.
