Abstract

Methods and systems that include receiving a plurality of reflectivity measurements on a semiconductor wafer. A reflectivity map is generated based on the received plurality of reflectivity measurements. The generated reflectivity map is used to determine a process parameter of an epitaxial growth process using the reflectivity map. In an embodiment, the process parameter is a power setting (heating) of a lamp of a CVD epitaxy tool.
