Waste-treatment processes are enhanced through generation and introduction of specific biological populations customized to perform or favor specific tasks either during the main process, or for solids minimization purposes in a post-treatment process. Specifically, embodiments of the present disclosure employ a halftone photoresist layer useful for reducing a number of masks needed to manufacture TFT backplane with fringe-field shifting). The plurality of prisms include reflecting prisms that reflect light from a light source that is disposed virtually on the reference axis and emit this light from the optical member. The method further includes operating each function unit during a respectively corresponding processing cycle to carry out a task with respect to one of the instructions, in order to produce a result.
