Job Description:

• 1) Prints reticles or patterns on optical lenses, metal films, and other materials used in optical instruments, using printing equipment: Cleans material surfaces to facilitate adherence of photoresist solution, using solvents and pumice.

• 2) Pours, brushes, or sprays photoresist solution onto material or dips material into photoresist tank to apply coating.

• 3) Places material into drier to set photoresist.

• 4) Positions material in vacuum printer, using handtools, such as tweezers and vacuum probe.

• 5) Positions and aligns reticle pattern or mask over top of material, using binocular microscope, and activates vacuum to hold assembly in alignment.

• 6) Sets printer time controls for specified exposure period and activates printer that exposes photoresist to light to print pattern onto material.

• 7) Develops photoresist image on material, using developing solution, and places printed material into drier.

• 8) May etch printed material, using etching equipment, or fill surfaces to specified thickness, using vacuum deposition equipment, to create reticle or pattern on material.

• 9) May prepare photo masks for reticle-making process, using photographic equipment.

• 10) May strip photoresist from material after etching or filling.
