Abstract:
A method for uniformly developing a photosensitive layer on a substrate, the method comprising the steps of:moving a developer head in a substantially linear relative motion with respect to the photosensitive layer on the substrate, wherein the step of moving the developer head is initiated at a first end of the substrate and is performed at a velocity;dispensing a developer material at a first controlled rate from the developer head during the step of moving the developer head; wherein contact of the developer material with the photosensitive layer commences a chemical reaction of developing;moving a rinse head in the substantially linear relative motion with respect to the photosensitive layer on the substrate, wherein the step of moving the rinse head is initiated at the first end of the substrate and is performed at the velocity; anddispensing a rinse material at a second controlled rate from the rinse head during the step of moving the rinse head; wherein contact of the rinse material with the developer material on the photosensitive layer retards the chemical reaction of developing.
