Semiconductor fabrication apparatus and pattern formation method using the same
Abstract
The semiconductor fabrication apparatus of this invention includes an exposure section (30) provided within a chamber (10) for exposing a design pattern on a resist film applied on a wafer (20), and a liquid recycle section (40) for supplying, onto the wafer, a liquid (23) for use in immersion lithography for increasing the numerical aperture of exposing light during exposure while recycling the liquid. The liquid recycle section includes a liquid supply part (41) for supplying the liquid onto the resist film (21) of the wafer, a liquid discharge part (42) for discharging and recovering the liquid from above the wafer, and an impurity removal part (43) for containing the liquid and removing an impurity included in the liquid.
