Patent JP-H08159726-A (JP)
Title: Pattern detection device
Inventor: KATO KINYA
IPC: G01B11/24
Filed: 1994-12-01
Abstract: PURPOSE: To accurately detect a pattern by separating the emission light flux of a traveling reflection means with reflection surfaces crossing each other into two light fluxes in different polarization state and photoelectrically detecting reflection light on a surface to be inspected from two openings. CONSTITUTION: Light flux through a cylinder lens 3 inverts its direction by a traveling reflection mirror 42 with two mutually crossing reflection surfaces, forms the image of line-shaped beams 4, and enters a beam splitter 5. The transmission and reflection light flux form line-shaped beams 9x and 9y with different longer directions and polarization directions through mirrors 8x and 8y and further forms line-shaped beams 13x and 13y on a surface to be inspected through an optical system. The beams 13x and 13y scan in y and x directions, respectively, along with the scanning of x direction of the reflection mirror 42. The regular reflection light returns a same light path, is synthesized by a splitter 5 and is separated again by a beam splitter 16 through a half mirror 2. Transmission and reflection light enter openings 17x and 17y at conjugate positions to surfaces to be inspected and is detected, thus simultaneously scanning two dimensions and achieving the common focusing of the detection means.
