IPC: G05D3/12
Filed: 1988-11-18
Abstract: PURPOSE:To enable highly accurate positioning by forming a diffraction grating with a center-to-center distance thereof differentiated slightly from a center-to- center distance of a slit. CONSTITUTION:A diffraction light intensity signal is turned to signals I and I' different slightly by DELTAd in peak because diffraction gratings 2 and 2' are formed with a center-to-center distance thereof differentiated slightly by DELTAd from a center-to-center distance (a) of slits 1 and 1'. An S-shaped curve signal can be obtained by computing the difference DELTAI=I-I' and hence, a mask 5 and a wafer 6 can be positioned easily utilizing the curve. In other words, utilizing a straight part of the curve signal, a feedback control of a stage 14 is performed in a positive way of X when DELTAI is positive while in a negative way of X when DELTAI is negative so that a signal intensity DELTAI approaches zero. This enables controlling of the mask 5 and the wafer 6 constantly thereby allowing a positioning control always following the wafer 6 even when the mask 5 is moved by a vibration, a thermal deformation and the like.
