Title:
EXPOSURE SYSTEM FOR CIRCUMFERENTIAL PART OF SUBSTRATE
Document Type and Number:
Japanese Patent JP3525976
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a circumferential part exposure system for substrate in which unnecessary resist can be exposed accurately at the circumferential part of a substrate.
SOLUTION: The inventive exposure system exposes a resist applied to a substrate W in a specified circumferential exposing region on the surface of the substrate W applied with resist. A control section controls a biaxial displacement mechanism to shift a spot light SL from a light irradiation means along two line components of outline of the circumferential exposing region based on a line data being obtained thus displacing the spot light SL and the substrate W relatively in the orthogonal X-axis and Y-axis directions.
