Claim Text:
1. A method for cleaning and drying a flat object, the method comprising: loading a flat object into a cleaning chamber and securing the flat object in a rotary-type flat-object-holding device; rotating the flat object substantially vertically with a variable-speed driving mechanism, the rotating being performed at a first rotational speed; cleaning the flat object by impinging a pressurized jet of a cleaning liquid onto a surface of the flat object-for a time T supplying a mist formed from a volatile liquid to the surface of the flat object; accelerating rotation of the flat object to a second rotational speed greater than the first rotational speed; rotating the flat object at the second rotational speed for a time T supplying a neutral gas supplied at least proximate to a central portion of the surface of the flat object to interact with the substantially homogenous layer of the solution; drying the flat object substantially vertically with a continuous supply of the neutral gas and rotation of the flat object at only the second rotational speed until substantial dryness of the flat object is achieved; discontinuing rotation of the flat object; and releasing the flat object from the rotary-type flat-object-holding device and removing the substantially dried flat object from the cleaning chamber.
