| Hot
Zone Design
A producer of electronic materials wanted
to modify its crystal growth furnaces to increase production
yield by rescaling the hot zone to grow larger diameter ingots.
We started with the existing crystal growth process and investigated
the effect of planned hardware modifications on heat transfer
in the equipment. Our analysis confirmed that the hot zone
could be redesigned to allow larger ingots to be grown in
the existing hardware. We designed and fabricated the new
hot zone and the modified furnaces are now routinely used
in large-volume production.
