Description
China Advanced Ceramic MeiVac 4.0″ diameter wafer stage substrate heater is configured for wafer applications. Like other members of the MeiVac substrate heater product line, it delivers superior uniformity and has been used for many R&D applications where reliability is critical. It is designed to operate under rigorous conditions and is both UHV and O2 compatible.
MeiVac wafer substrate heaters are made of Inconel metal and are wafer size specific. Wafer pockets are machined into the surface of the heater blocks. Note that Inconel is NOT compatible with silver thermal paste.
