Job Description:

• 1) Sets up and operates computer-controlled epitaxial reactor to grow layer of semiconductor material on wafer surface, following written specifications: Removes semiconductor wafers from tray, using vacuum wand, and cleans wafers, using blow-off wand.

• 2) Positions wafers on carousel and aligns carousel on baseplate of reactor.

• 3) Enters processing data into computer to start rotation of baseplate and to activate vacuum pump and epitaxial growth process program.

• 4) Observes display screen to monitor epitaxial growth process.

• 5) Inspects wafers for defects, such as scratches, growths, and pits, and calculates defects per square inch, using calculator.

• 6) Measures thickness and bow of wafer and thickness and photo-luminescence of epitaxial layer, using gauges and test equipment.

• 7) Calculates surface area of wafer surface, using calculator.

• 8) Inscribes line on wafer, using metal scribe, and breaks off section of wafer.

• 9) Cuts line on light bar sample to isolate die, using wafer saw, and measures brightness of die, using probe tester.

• 10) Constructs sheet metal housing and installs and repairs electrical wiring, water and gas lines, switches, and gauges on reactor following oral instructions, blueprints, and specifications, using handtools and power tools.

• 11) Checks replacement gas cylinder for leaks before installing on reactor, using leak detector.

• 12) Connects reactor to computer, using handtools and power tools.

• 13) Enters information into computer, using keyboard, to activate program to clean reactor, and cleans and replaces reactor accessories, such as bell jar and carousel.
