It is recommended that wafers be transferred from the MAC to a 450 FOUP and 450 FOUP to MAC

F12100 - SEMI F121 - Guide for Evaluating Metrology for Particle Precursors in Ultrapure Water ElnTpc-Safety - Facility/Workplace Saw marks are frequently specifiedThis Guide provides a performance based definition of metrology that can be used to measure particle precursors in ultrapure water (UPW). This Guide includes a testing methodology and criteria for qualifying measurement techniques for quantifying particle precursor concentrations in UPW. Particle precursors are defined as dissolved compounds that can form particles when dried on a wafer surface. This definition was developed by the UPW International
