    摘要: The present invention relates to a plate type heat exchanger having a heat exchange element composed of two plates for exchanging heat between a fluid flowing inside the heat exchange element and a fluid flowing outside the heat exchange element. In the plate type heat exchanger, the two plates (1) have a plurality of depressions (8), and the depressions are brought into contact with and bonded to each other. Peripheral portions of the plates are sealed to form a space in which a fluid flows and constitute a heat exchange element (2) having opening portions (5, 6) at both ends thereof. The heat exchange elements (2) are piled on and bonded to each other so that the opening portions (5, 6) communicate with each other.

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: A focusing method is disclosed wherein a substrate is moved substantially along a focal plane of a projection optical system up to a predetermined station adjacent to the focal plane of the projection optical system and then, at the predetermined station, the surface of the substrate is brought into substantial coincidence with the focal plane of the projection optical system.

    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.

    摘要: Step-and-repeat exposure apparatus for printing, by way of a projection optical system, images of a pattern formed on a reticle upon different portions of a semiconductor wafer, placed on a movable stage, is disclosed. On the portion of the movable stage other than the portion upon which the semiconductor wafer is placed, an erasably writable recording medium such as, for example, a magneto-optic recording material or a photochromic material is provided. An image of a mark of a reticle is formed on the recording medium by use of the projection optical system, the thus formed image being photoelectrically detected. From the result of the detection, alignment information concerning, for example, a magnification error, a focus error, a positional error between the reticle and the wafer, for example is obtained.
