"Reclaiming" is well-known as an inexpensive source for monitor, test or prime wafer. Since 1992 it is also available for GaAs and InP. The idea to recycle used wafer is obvious for economic reasons. You get inexpensive wafer with best bulk properties. The only difference to prime material is a thickness loss of few micron. Since all coatings are completely removed the surface has all properties of prime wafer. Even a repeated reclaiming is no problem.
When Wacker-Siltronic in Burghausen sold its compound semiconductor activities to Freiberger (FCM) in 1992 III/V-Reclaim started as a spin-off the reclamation of GaAs and InP. After 20 years of business and continuous process improvement we are the leading company worldwide offering a reclaim service for GaAs, InP, InSb and Ge wafer.
