Abstract:  This SEMASPEC defines a method of testing surface features in the nanometer
size range. Three-dimensional data can be obtained from a surface, which can
then be used to produce a model of the surface texture or to measure surface
morphology. The purpose of this procedure is to evaluate components
considered for use in ultra-high gas distribution systems. Application of
this test method is expected to yield comparable data among components tested
for the purposes of qualification for installation. This document is in
development as an industry standard by Semiconductor Equipment and Materials
International (SEMI). When available, adherence to the SEMI standard is
recommended.
