  • Patent number: 4952060
    Abstract: A projection exposure apparatus is disclosed for exposing a semiconductor wafer to a pattern, formed on a reticle, by projection using a projection lens system. The apparatus includes an alignment optical system disposed at a side of the wafer remote from the projection lens system. The alignment optical system is used to detect an alignment mark provided on the wafer, from the back of the wafer. In accordance with the detection, the wafer is moved so that its alignment mark is brought into a predetermined positional relation with the alignment optical system, whereby the reticle and the wafer are relatively aligned. With this arrangement, the wafer alignment mark can be detected without being adversely affected by a resist layer applied to the wafer surface. Thus, the reticle and the wafer can be aligned very accurately.

  • Patent number: 4814829
    Abstract: A projection exposure apparatus for projecting a pattern of a reticle upon a wafer by use of a projection lens system, is disclosed. The apparatus is arranged so that a mark illuminating light is projected upon the wafer from between the projection lens system and the wafer and not by way of the projection lens system. The light diffracted by an edge of a wafer alignment mark is photoelectrically detected by way of the projection lens system, whereby an electrical signal corresponding to an image of the alignment mark is obtained. On the basis of the detected signal, the wafer is aligned with the reticle. This arrangement allows detection of the alignment mark without being affected by a photoresist applied to the wafer surface. Thus, the reticle-to-wafer alignment can be made accurately. Also, a novel and unique alignment method is disclosed. The disclosed method assures high-accuracy reticle-to-wafer alignment.
