The holder includes a body part, and an igniter fixing engagement part and a cup fixing engagement part projecting from the body part. These engagement parts are bent, so that the igniter and the cup are fixed by crimping to the holder. The engagement parts are both finish shaped by forging processing. A metal flow appearing in superficial layers of the engagement parts extends continuously from the body part through the engagement parts to return to the body part, without being divided in surfaces of the engagement parts.

摘要： An exposure apparatus is used for reproducing a mask pattern of a semiconductor device or the like onto a photosensitive substrate using a holography. The holography is utilized also in a process for alignment between a mask pattern hologram and an exposure region of the substrate. The pattern hologram is recorded to a recording medium by interference between an object wave from the pattern and a reference wave, and a second hologram is formed to the medium by diffraction light from an alignment mark formed on the mask. Prior to reconstruction of the pattern image, reconstruction light from the second hologram, illuminated with a reconstruction wave, is irradiated onto the substrate arranged in place of the mask. A reproduction image of the alignment mark on the substrate surface illuminated with the reconstruction light is measured, and relative displacement between the medium and the substrate is detected from a result of the measurement. The relative positional relationship between the medium and the substrate is corrected in accordance with the displacement information, and, thereafter, the surface is exposed with a reconstruction image of the pattern hologram.

摘要： Alignment of a mask with a projection-type exposing apparatus and alignment of the mask with a substrate are provided. Plural exposure areas of the substrate are exposed by light of a predetermined wavelength, which is also used for alignment purposes to reduce alignment error due to aberration of a projection optical system. A first alignment mark is disposed in a first area between adjacent exposure areas of the substrate. The mask has a main area, a second area in which a second mark is disposed, and a third area in which a third mark is disposed, the second area being outside of the main area and the third area being inside the second area. An illuminating device has a first status in which the second and third areas are illuminated simultaneously and has a second status in which the third area is illuminated, a first area adjacent to one of the exposure areas also being illuminated when the illuminating device has the second status. In the first status, a first detector detects the position of an image of the second mark formed by an objective optical system. In the second status, a second detector detects displacement between images of the first and third marks formed by the objective optical system and produces a detection signal. The mask is displaced relative to the substrate in response to the detection signal, so that the images of the first and third marks assume a predetermined relationship.
