A new QC tool for quantitative surface analysis

Article Abstract:

Optical scatterometry provides a quick and noncontact assessment of surface quality. With the emergence of inexpensive hand-held devices, the technique rapidly grew in popularity in a variety of applications involving rapid quantitative surface analysis. Optical scatterometry instruments can measure surface finish parameters such as RMS and Ra ranging from 0.04 microinch to tenths of a microinch and can perform multiple measurements on areas covering several millimeters in less than a second. It can also be made to create surface maps and detect various surface defects, blemishes or dust.
