    摘要： A system and method is provided that facilitates the application of a uniform layer of developer material on a photoresist material layer. The system includes a multiple tip nozzle and a movement system that moves the nozzle to an operating position above a central region of a photoresist material layer located on a substrate, and applies a volume of developer as the nozzle scan moves across a predetermined path. The movement system moves the nozzle in two dimensions by providing an arm that has a first arm member that is pivotable about a first rotational axis and a second arm member that is pivotable about a second rotational axis or is movable along a translational axis. The system also provides a measurement system that measures the thickness uniformity of the developed photoresist material layer disposed on a test wafer. The thickness uniformity data is used to reconfigure the predetermined path of the nozzle as the developer is applied. The thickness uniformity data can also be used to adjust the volume of developer applied along the path and/or the volume flow rate.

    摘要： A system and method is provided that facilitates the application of a uniform layer of developer material on a photoresist material layer. The system includes a nozzle adapted to apply a predetermined volume of developer material on a photoresist material layer along a linear path having a length approximately equal to the diameter of the photoresist material layer. A movement system moves the nozzle to a first position offset from a central region of the photoresist material layer for applying a first predetermined volume of developer material to the photoresist material layer while the developer material is spin coated. The movement system also moves the nozzle to a second position offset from the central region for applying a second predetermined volume of developer material to the photoresist material layer while the developer is spin coated. The first position is located on an opposite side of the central region with respect to the second position. A method of adjusting the offset position and/or volume of developer material applied at the first and second position is also provided. The method utilizes developed photoresist material layer thickness data provided by a measurement system to adjust the offset position and/or volume of the developer.
