Abstract:
1. A method for combinatorially processing a substrate, the method comprising: delivering a first fluid to an open staging vessel; withdrawing the first fluid from the open staging vessel into a segment in fluid communication with the staging vessel; delivering a second fluid, different from the first fluid, to the open staging vessel; withdrawing the second fluid from the open staging vessel into the segment wherein the first and second fluids are disposed with the segment; transitioning a valve to disable the withdrawing and enable dispensing of the fluid into a reactor isolating a portion of the substrate, wherein the reactor comprises an outlet; forcing the second fluid from the segment into the reactor such that the second fluid flows from the reactor through the outlet of the reactor; forcing the first fluid from the segment into the reactor after the second fluid is forced from the segment such that the first fluid flows from the reactor through the outlet of the reactor; and restricting the flow of the second fluid and the first fluid through the outlet of the reactor such that the second fluid and the first fluid are pressurized within the reactor.
