TITLE(s): INTEGRATED CIRCUIT FABRICATOR (electron. comp.) alternate titles: wafer fab operator
Performs any combination of following tasks to fabricate integrated circuits on semiconductor
wafers according to written specifications: Loads semiconductor wafers into processing containers
for processing or into inspection equipment, using tweezers or vacuum wand. Cleans and dries photo
masks and semiconductor wafers to remove contaminants, using cleaning and drying equipment. Inspects
photo masks and wafers for defects, such as scratches, using microscope, magnifying lens, or
computer-aided inspection equipment. Deposits layer of photoresist solution on wafers, using
automated equipment. Aligns photo mask pattern on photoresist layer, exposes pattern to ultraviolet
light, and develops pattern, using specialized equipment. Alters electrical nature of wafer layers
according to photo mask patterns to form integrated circuits on wafers, using equipment, such as
acid baths, diffusion furnaces, ion implant equipment, and metallization equipment. Removes
photoresist from wafers, using stripping chemicals and equipment. Inspects and measures circuitry
for conformance to pattern specifications, using microscope with measuring attachment. Tests
functioning of circuitry, using electronic test equipment and standard procedures.
