I worked front nights (Sunday- Tuesday, every other Saturday) in the Photo department as a production specialist, loading cassettes of silicon wafers onto lithocells for processing. During a typical day, I would gather flowsheets for specific jobs and scan out the cassettes, load the appropriate reticles into the lithocells, perform daily e-clear and diagnostic tests, and help others within my respective or nearby aisle. I also learned overlay, where one wafer from each cassette would be tested to make sure that proper processing had occurred before the cassette moved on to microscope or CDSiM. I had very helpful leads and coworkers, and the most enjoyable part of the job was being able to move to different aisles and learn new tools. The most difficult part was, at times, waiting to be trained on different tool sets, and performing certain chemical changes.
