Abstract
The inventive dispenser mechanism uniformly develops a photosensitive layer on a substrate. The mechanism uses a developer head that moves in a substantially linear relative motion with respect to the substrate and dispenses a developer at a controlled rate. Contact of the developer material with the photosensitive layer commences a chemical reaction of developing. The mechanism also uses a rinse head that has the same motion as the developer head and travels at the same velocity. The rinse head dispenses a rinse material at a controlled rate. Contact of the rinse material with the developer material on the photosensitive layer retards the chemical reaction of developing. The rinse head waits for a predetermined dwell period after the developer head has dispensed the developer material before dispensing the rinse material. The mechanism may also use a suction head that has the same motion and velocity and removes loose material on a surface of the substrate.
