Patent ID: 8441653

Claim:
An apparatus for performing non-contact material characterization on substrates, comprising: (a) an epitaxial growth apparatus having a processing chamber for depositing a material on a substrate held on a top surface of a wafer carrier; and (b) a non-contact material characterization device, said non-contact material characterization device being constructed and arranged to perform a non-contact material characterization technique over a two-dimensional area of said top surface of said wafer carrier, said two-dimensional area including a plurality of said substrates, and said non-contact material characterization device being constructed to obtain a plurality of measurements from different locations spread across said two-dimensional area; wherein said apparatus is constructed to associate each of said measurements with a geometrical position of said location from which said respective measurement was obtained, and wherein said apparatus is constructed to link each of said measurements obtained from locations on said substrates with a particular substrate from which said respective measurement was obtained.
