Latest Patents

One of Karl's latest patents is titled "Reclaim function for semiconductor processing system." This invention involves systems designed for controlling fluids in semiconductor processing. The disclosed systems include a chemical blender, a reclaim tank, a dispense system, two chemical monitors, a controller, and a reclamation line that connects to the outlet of the process station and is coupled to the reclaim tank. The reclaim tank is responsible for mixing solutions from the chemical blender and the reclamation line. One of the chemical monitors tracks the mixed solution downstream from the dispense system. The controller is programmed to direct the mixed solution to the process station once the first chemical monitor confirms that at least one chemical compound in the mixed solution reaches a predetermined concentration. The second chemical monitor assesses the reclaimed portion of the mixed solution to ensure that the chemical compound is at the required concentration before it is reintroduced into the reclaim tank.

Another embodiment of his patent describes a method for controlling fluids in a semiconductor processing system. This method includes mixing two or more chemical compounds in a blender to create a solution, which is then supplied to a reclaim tank. The solution is dispensed to a process station, where it is monitored to verify that at least one of the chemical compounds meets the predetermined concentration. If the concentration is confirmed, the solution is directed to the process station. Additionally, the method involves removing a portion of the solution from the process station and returning it to the reclaim tank, where it is also monitored for concentration before being reused.
