Abstract:
A developing apparatus comprising:a substrate holding element substantially horizontally holding a substrate; a developer supply element having a slitlike first discharge port discharging a developer for relatively moving in a first horizontal direction with respect to said substrate and discharging said developer onto said substrate from said first discharge port thereby obtaining a puddle of developer covering the overall upper surface of said substrate; a rinse supply element having a slitlike second discharge port discharging a rinse for relatively moving in said first horizontal direction with respect to said substrate and discharging said rinse onto said substrate from said second discharge port thereby stopping development with said puddle of developer; and an anti-flow element preventing: i) a first stream of said rinse, discharged onto said substrate from said second discharge port, flowing frontward in said first horizontal direction, and ii) a second stream formed by said puddle of developer washed away by said rinse frontward in said first horizontal direction.
