TITLE(s): CRYSTAL GROWER (comm. equip.; electron. comp.) alternate titles: crystal growing furnace
operator
Sets up and operates furnaces to grow semiconductor crystals from materials, such as silicon,
quartz, or gallium arsenide: Loads furnace with seed crystal, dopant, and crystal growing materials,
such as polysilicon, quartz, gallium arsenide, or remelt. Reads work order and adjusts furnace
controls to regulate operating conditions, such as power level, temperature, vacuum, and rotation
speed, according to crystal growing specifications. Monitors meltdown of growing material and
crystal growth, and adjusts furnace controls. Shuts down furnace and unloads crystal ingot after
cooling. May clean inside furnace, using vacuum cleaner and cleaning supplies, and replace furnace
liner and other parts. May weigh and crop crystal ingot, slice sample wafer, measure and test ingot
for resistivity, and determine crystal orientation [INSPECTOR, CRYSTAL (electron. comp.)
726.684-054]. May operate computer controls to regulate furnace conditions.
