Claims
- 1. An exposing method for exposing a surface of a target using an exposure apparatus having
- a mask with a pattern,
- an energy source generating an exposure beam to expose the pattern on the mask on the surface of the target when the target is located in a path of the exposure beam,
- holding means for alternately holding and releasing the target,
- carrying means for carrying the target to the holding means, shifting means for coarsely shifting the holding means in a direction perpendicular to the surface of the target between a first location where the target is alternately held and released, and a second location where the target is exposed, and
- moving means for finely moving said holding means when said holding means is in the second location, the first location being closer to the moving means than the second location,
- the method comprising the steps of:
- (a) shifting the holding means to the first location using the shifting means;
- (b) carrying the target to the holding means using the carrying means;
- (c) holding the target with the holding means;
- (d) shifting the holding means from the first location to the second location using the shifting means;
- (e) fixing the holding means to the moving means;
- (f) adjusting the exposing position of the target at the second location using the moving means; and
- (g) exposing the target to the pattern on the mask with the exposure beam.
- 2. The method according to claim 1, wherein the step of shifting the holding means to the first location includes the step of fixing the holding means to the moving means when the holding means has reached the first location.
- 3. The method according to claim 1, wherein the step of adjusting the exposing position of the target at the second location includes the step of detecting a gap between the target and the mask to finely adjust the gap.
- 4. The method according to claim 1, wherein a gap between the target and the mask at the first location has a width in which the carrying means is able to be inserted.
- 5. The method according to claim 1, wherein a gap between the target and the mask at the second location has a suitable width for exposure.
- 6. The method according to claim 1, wherein the exposure beam is an electromagnetic radiation beam.
- 7. The method according to claim 1, wherein the exposure beam is an X ray beam.
- 8. The method according to claim 1, further comprising the steps of:
- (h) shifting the holding means with the exposed target to the first location using the shifting means after the step of exposing the target is finished; and
- (i) carrying the exposed target from the holding means using the carrying means.
- 9. The method according to claim 8, wherein the step of shifting the holding means with the exposed target to the first location includes the step of fixing the holding means to the moving means when the holding means has reached the first location.
