    Abstract: PROBLEM TO BE SOLVED: To provide a device which can minimize ripples and turbulence associated with the energy transfer between the movement of a lens and a liquid environment.
    SOLUTION: An apparatus for immersion optical lithography has a lens capable of relative movement in synchronization with horizontal motion of a semiconductor wafer in a liquid environment. The synchronized movements of the lens apparatus and the semiconductor wafer advantageously reduce turbulence and air bubbles associated with the liquid environment. The relative motions of the lens and the semiconductor wafer are performed almost simultaneously with a scanning process, resulting in optimal image resolution with minimal air bubbles, turbulence, and disruption in the liquid environment.
