Abstract: An embodiment provides point-of-use blending of photoresist rinse solutions for patterned photoresists. The disclosed methods and systems form different mitigation solutions for a plurality of different photoresists through point-of-use variable blending of a mitigation solution with deionized water and/or other chemical substances to adjust formulation of the solution right before dispensing the solution within a process chamber. In one embodiment, different surfactant rinse solutions are used for different photoresists, such as different extreme ultraviolet photoresists. In addition, a level of a reactive component, a level of a nonreactive component, or both within a mitigation solution is able to be adjusted by using the point-of-use blending to provide the adjusted mitigation solution. An ability to make point-of-use adjustments to a solution chemical substance right before dispensing the solution on a microelectronic workpiece, such as a semiconductor wafer, improves an interaction between the adjusted mitigation solution and the patterned photoresist.
