A professional who immerses semiconductor wafers in series of chemical baths to etch circuitry patterns into or to strip excess photoresist from wafer surfaces. Respnsibilities include:

• Places semiconductor wafers in containers, such as boats or cassettes, using vacuum wand or tweezers.
• Immerses loaded containers in series of chemical and water baths to etch circuitry patterns into or strip excess photoresist from wafer surfaces.
• Places loaded container into air or spin dryer and pushes buttons to activate drying cycle.
• May visually inspect etched and stripped wafer, using microscope, to detect scratches, contaminants, and to verify conformance to specifications.
• May tend plasma (gas) etch machine to etch circuitry patterns into wafer surfaces.
• May clean and maintain chemical baths.
