Abstract: An exposure apparatus and an exposure method that minimize the range over which exposing light becomes defocused even when a non-level portion is present within each shot are provided. One shot is selected from a plurality of shots (exposure unit areas) set on a wafer (S 50). 49 measurement points are set in the selected shot and the three-dimensional coordinates of each measurement point are determined (S 70). Next, an arithmetic operation is performed using the 49 sets of three-dimensional coordinate data to ascertain an “in-shot focus plane” (S 90). This arithmetic operation may be performed through, for instance, the method of least squares. The extents of positional deviation between the surface of the selected shot and the in-shot focus plane is ascertained and the extents of deviation are stored in memory as “adjustment values” (S 110). An exposure shot to undergo exposure processing is selected and the surface level variation manifesting at the exposure shot is measured.

The joining mechanism is constructed so that an inner cylindrical portion (22b) is pressed in a first coupling section (11a), an annular bead (2a) formed on an outer cylindrical portion (22a) squeezes a second coupling section (11b), and a bead (2c) formed on a step (22c) is pressed against the front end surface (1a) of the first coupling section when an annular ridge (1b) formed on the second coupling section (11b) is fitted in an annular groove (2b) formed in the outer cylindrical portion (22a). A ball holding tube (7) is provided with a ball housing bore (7b) and a connecting bore (7d) formed so that a low step is formed between the ball housing bore and the connecting bore. The edge of the tip of the ball holding tube is rounded. A head member is provided with a spring support portion (2f) for supporting a coil spring (8), provided with slots (2g).

Abstract: A cap is fitted onto an engagement portion of a main body such as that of a writing implement, paint applicator, make-up applicator, or container. An inner wall of the cap is provided with a flexible operating member having a free end capable of bending inward. An oblique guide surface is formed on at least one of the main body and the cap such that the cap can be separated from the main body by pressing the operating member inward.

Abstract: Alignment marks used in different processes are arranged on scribing lines. The scribing lines are used for cutting off individual semiconductor devices formed on a wafer, and the alignment marks have widths which are larger than widths of the scribing lines. The width of areas corresponding to positions where alignment marks are formed are larger so as to accommodate the alignment marks within the areas. A part of the area of a used alignment mark is covered with a new film so that the area is permitted to have a scribing line having a desired width every time a used alignment is generated. A new alignment mark is arranged within other areas where an alignment mark is not formed. In such an arrangement of the alignment marks, the center line of the scribing line is made clear, and the area where the semiconductor devices are formed can be made large.
