Title: Method for detecting height of sample surface and apparatus therefor
Inventor: OSHIDA YOSHITADA
IPC: G03F7/20
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To accurately measure the height of an object by obliquely irradiating the surface of a measured object with light having relatively higher directivity so that the angle of incidence of the main light beam thereof exceeds a specified value. SOLUTION: Light emitted from a semiconductor laser 1 is admitted into a wafer 4 at an angle of incidence of 85 deg. or the more to form an image of a light source with a condenser lens 11' within an exposure area on the wafer. The reflected light is condensed onto a light position detector 3" by a mirror 210 and lenses 21 and 22. When the surface of the wafer is at a resist pattern imaging position in an exposure optical system, the light stays at the center of the light position detector 3", when it deviates vertically, it shifts horizontally from the center of the light position detector 3", and a detection signal of the light position detector 3" is sent to a processing circuit 5 to allow accurately focusing constantly by driving and controlling upper/lower wafer moving tables.  When it is so arranged that the polarized light of a laser light is admitted into the surface of the wafer by S polarization, the height of the surface of a photoresist can be accurately determined.
