    Abstract: A method of controlling a feedback control system of a semiconductor process chemical fluid in a storage tank includes performing a fluid quality measurement of fluid by a spectrum analyzer positioned adjacent to a dispensing port of the storage tank, and determining whether a variation in fluid quality measurement of the fluid is within an acceptable range. The method further includes in response to a variation in fluid quality measurement that is not within the acceptable range of variation in fluid quality measurement, automatically adjusting a configurable parameter of the semiconductor process chemical fluid in the storage tank to set the variation in fluid quality measurement of the fluid within the acceptable range.

    Abstract: A nozzle assembly for use in liquid-dispensing system, the nozzle assembly including: a body configured to receive a pipe; and the pipe, an end of the pipe being mounted on the body. The pipe includes multiple lumens correspondingly terminated in multiple orifices such that a liquid is escapable from each lumen through the corresponding orifice and is thereby dispensable from the nozzle assembly. The pipe has a first flow-capacity to supply a first volume of the liquid at a first flow-rate and at a first pressure. Each orifice and corresponding lumen has a second flow-capacity to supply a second volume of the liquid at a second flow-rate and at a second pressure.

    Abstract: A wafer cleaning method for cleaning contaminants on a wafer is provided, wherein the backside of the wafer has a clear area and an unclear area, and the contaminants are located in the unclear area. The wafer cleaning method includes inspecting the backside of the wafer and generating an inspection signal by an inspection device. The wafer cleaning method includes generating a control signal according to the inspection signal by a process module, wherein the control signal includes movement information of a brush element according to coordinates of the contaminants obtained from the inspection signal. The wafer cleaning method includes controlling the brush element to clean the contaminants on the backside of the wafer according to the control signal by a control device along a predetermined path.
