SEMI E101 - Guide for EFEM Functional Structure Model
NOTICE: This Standard or Safety Guideline has an Inactive Status because the conditions to maintain Current Status have not been met. Inactive Standards or Safety Guidelines are available from SEMI and continue to be valid for use.
Productivity improvement is the task with the highest priority in semiconductor factories of the 300 mm generation, and computer-integrated manufacturing or factory automation (CIM/FA) technologies become more and more important to accomplish it. The standardization of these technologies is also necessary to provide the CIM/FA infrastructure in a short period of time at a low cost. Since the standards will have to cover a wide range of production equipment, communication hardware, and software tools, it is very important that the standards have a high degree of compatibility. In order to improve the compatibility, this Guide provides a functional structure model of an Equipment Front End Module (EFEM) that handles carriers and substrates at the interface between the factory material handling system and the process equipment.
The major purposes of this Guide are as follows:
1. provide a common understanding of functions of EFEM and associated interfaces between functional elements (components with particular function roles),
2. provide a common understanding of the hierarchical structure of functions and their interfaces in an EFEM,
3. provide a common understanding of possible units used for maintenance, adjustment, and control, and
4. provide a map between EFEM functional elements and existing standards.
