6-inch VCSEL wafer fabrication manufacturing advances
David Cheskis, Director of Optical Products - Anadigics
GaAs-based VCSELs are being employed in an increasing number of high-volume applications. This trend places pressure on existing manufacturing resources and is the catalyst for the current wave of capacity expansion. VCSEL wafer fabrication using 6-inch diameter substrates is proven to solve capacity and economic constraints, while also providing advanced wafer processing tools, techniques and capabilities to deliver additional manufacturing advantages. This presentation describes VCSEL manufacturing advances, product improvements and market implications made possible by a 6-inch wafer fabrication process.
