摘要： An exposure method for transferring a device pattern to a resist, wherein the device pattern includes a first element and a second element having a linewidth narrower than the first element. The method includes a first exposure step for exposing the resist by use of an interference fringe, produced by interference of two light beams, through an exposure amount substantially not greater than a threshold of the resist, and a second exposure step for exposing the resist with a light pattern related to the first and second elements. A light component, of the light pattern, related to the first element bears an exposure amount greater than the threshold, a light component, of the light pattern, related to the second element bears an exposure amount not greater than the threshold and is to be combined with light in a portion of the interference fringe, and a sum of the exposure amount of the light component related to the second element and an exposure amount provided by the light in the portion of the interference fringe is greater than the threshold.

摘要： An optical system is arranged so that a scanning light beam for scanning a first region to be inspected and a scanning light beam for scanning a second region to be inspected are not simultaneously incident upon an object to be inspected. This prevents an adverse influence on the inspection caused by flare light generated when one scanning light beam is incident upon an edge of the object and is received by a light-receiving optical system for the region to be inspected scanned by another scanning light beam. The system includes two polygon mirrors provided as one body in an optical system at a position for projecting the light beams so that the distance between a focus point of the light beam projected on the lower surface of the object and a focus point of the light beam projected on the upper surface of the object in the beam scanning direction is greater than the width of the object in the beam scanning direction. As a result, the two light beams are alternately incident upon the object.
