    The etching of uniform, repeatable GaAs/AlGaAs mesas is an important step in manufacturing VCSELs. This paper presents a high uniformity, low foot etching of mesa structures on 6” wafers. The improved uniformity permits the use of production-friendly optical endpoint techniques which can be used to stop on a specific layer in the VCSEL structure.
