The boat is now loaded into the mouth of the furnace. A pushrod is then used to move the boat into the furnace. The hook at one end of the pushrod grips the notch at the end of the wafer boat. The pushrod is made of the same heat resistant quartz material as the boat.
As the boat and its wafers are loaded, we will fade away the walls of the furnace to better see how it works. Here we see the loops of heater wire that surround the central tube of the furnace.
