Substrate processing apparatus and substrate processing method
A substrate processing apparatus removes foreign substances from a substrate at high removal efficiency. The substrate processing apparatus includes: a scrubber to perform surface processing of the substrate by bringing a scrubbing member into sliding contact with a first surface of the substrate, a hydrostatic support mechanism for supporting a second surface of the substrate via fluid pressure without contacting the substrate, the second surface being an opposite surface of the first surface, a cleaner to clean the processed substrate, and a dryer to dry the cleaned substrate. The scrubber brings the scrubbing member into sliding contact with the first surface while rotating the scrubbing member about a central axis of the scrubber.
1. A tape cartridge comprising:
a tape feeding reel configured to feed a scrubbing member in a form of tape;
a tape winding reel configured to wind the scrubbing member;
a press member configured to press the scrubbing member;
a first reel shaft secured to the tape feeding reel;
a second reel shaft secured to the tape winding reel;
a first bearing rotatably supporting the first reel shaft;
a second bearing rotatably supporting the second reel shaft;
a reel housing to which the first bearing and the second bearing are secured;
