1. Scope |
This standard was transferred to SEMI (www.semi.org) May 2003 1.1 This practice covers the determination of the accuracy with which a scanning surface inspection system (SSIS) reports the positions of localized light scatterers on a silicon wafer surface. Note 1-This practice was developed primarily for use with laser-based SSISs. Although it may also be applicable for determining the positional accuracy capabilities of other types of SSISs, the conditions for which this extension of the practice might be valid have not been determined.1.2 This practice includes procedures to separate the influences of wafer handling and wafer orientation on the precision and bias of the positions reported. 1.3 The procedure must be carried out on an SSIS that is located in a Class M2.5 (Class 10) or better environment as defined in Federal Standard 209E. 1.4 This practice relies on a fabricated silicon reference wafer that contains a prescribed pattern of multiple etched feature fields on its polished (front) surface. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
