Nanometrics presents the QS-1200 desktop system                                 Easy to Use
for dopant monitoring, epi thickness measurement,
and other applications. The QS-1200 is designed for
advanced semiconductor fabs performing material                                 In its basic configuration, the instrument consists of an
characterization in silicon growing and device manu-                            FTIR-based optical console and a manual wafer tray to
