A professional who tends etch machine and equipment that remove metal and photoresist and etches electronic circuitry into metallized substrate of wafer surface, according to processing specifications. Respnsibilities include:

• Places wafers in boats, using tweezers or vacuum wand.
• Places boats in etch machine or equipment.
• Turns dials, sets timer and gauges on equipment, or presses buttons on machine to activate etch cycle to etch or remove materials from wafer surface, such as metal or photoresist.
• Inspects wafer to verify that wafers are not over-etched and that photoresist has been removed, using microscope.
• May measure specified dimensions of wafers, using microscope measuring attachment.
• May manually immerse loaded boats into chemical solution baths to etch circuitry into wafer surface.
