Abstract
A component (10 or 12) of a flat-panel display is cleaned with a fluid having a mole-fraction dominant constituent. The cleaning operation is performed by subjecting the component to the cleaning fluid while its absolute pressure exceeds the absolute pressure at the triple point of the dominant constituent and is at least 20% of the absolute pressure value at the critical point of the dominant constituent. The temperature and pressure of the cleaning fluid are typically controlled in a direction toward the supercritical state of the dominant constituent.
