Substrate Heater – 2.0″ Wafer Stage – High Temperature Resistive

MeiVac substrate heaters were designed to operate under rigorous conditions and they are both UHV and O2 compatible. Known for their unprecedented temperature uniformity, the HTR heaters have been used for some very demanding applications. They have been used in sputtering, laser ablation, ion beam deposition, ECR, MOCVD among others. In 2012 MeiVac developed the VTAC – Variable Temperature AC controller to provide a closed loop control package for the HTR heater stages.
