<P>PROBLEM TO BE SOLVED: To provide apparatus and methods for closed-loop control utilized in printing a multilayer pattern on a substrate. <P>SOLUTION: In one embodiment, a solar cell formation process is provided. The process comprises positioning a substrate on a substrate receiving surface of a printing station, printing a first patterned layer on a region of the substrate, acquiring a first image of the first patterned layer, storing the first optical image in a buffer, and printing a second patterned layer over the region of the substrate, where the second patterned layer is aligned over the region of the substrate using information received from the acquired first optical image. <P>COPYRIGHT: (C)2013,JPO&INPIT |
