Patent Searching and Data


Title:
露光装置、投影光学系、デバイスの製造方法
Document Type and Number:
Japanese Patent JP4378109
Kind Code:
B2
Abstract:
The apparatus has an illumination optical system to illuminate a pattern on an object with light supplied from a semiconductor laser light source (1a). A projection optical system projects an image of the pattern onto a plate. A photosensor (4a) detects a positional offset of the pattern image. A mirror drive (6) inclines a mirror (M2), and moves the mirror by a minute amount in an optical-axis direction based on the offset. An independent claim is also included for a device fabrication method.
