The Tempress S2T1 Storage 4" & 6" is used as a storage furnace for wafers/samples that have gone through the RCA pre-furnace clean procedure, prior to any clean furnace run. The wafers are stored in a Nitrogen ambient, at a temperature of 350°C.


  • New wands - Vespel is a softer material and should do less damage to double sided polished wafers. The drawback to Vespel is that it can't take as much heat as a quartz wand tip. The maximum sustainable temperature for Vespel is 288C. So make sure you allow enough time for the wafers to cool prior to handling them. Once the boat has traveled all the way out of the tube you will need at least 10 minutes for the storage tube and a minimum of 15 minutes for tubes
