A tray carrier with ultraphobic surfaces for promoting more effective cleaning
and drying of the tray carrier. In the invention, entire surfaces or portions of
surfaces of a tray carrier are made ultraphobic. The ultraphobic surfaces of the
tray carrier cause liquids that may come in contact with the surface, such as may
be used in cleaning, to quickly and easily "roll off" without leaving a liquid
film or substantial quantity of liquid droplets. As a result, less time and energy
is expended in drying the surfaces, and redeposited residue is minimized, thereby
improving overall process quality and facilitating economical reuse of the tray
carrier. In addition, the ultraphobic surfaces may be resistant to initial deposition
of contaminants, where the contaminants may be in liquid or vapor form.
