Advances in optical metrology equipment are helping the semiconductor industry increase productivity and reduce downtime, finds Keely Portway
In deflectometry, a camera images fringe patterns that have reflected off a surface under test, so that a system can deduce a map of the surface slopes from the deviation of the projected fringes, and from that determine the surface shape. Credit: Mahr
Lens features have been getting too small to properly characterise – but metrology providers are catching up, finds Andy Extance
