Yellow Room - because photoresist is sensitive to ultraviolet light, ultraviolet light must not be present in photoresist processing rooms. The filters used to remove ultraviolet light from the output of fluorescent lights give the room a yellow appearance.
Yield - the number of units good after some test or measurement divided by the number of units measured.
Yield Learning - the identification of yield limiting defects, analysis of the cause of the defect and corrective action to fix the defect and improve yield.
Yield Model - a mathematical probability model used to convert defect density to a projected yield.
