Abstract: An electron beam exposure apparatus is disclosed that does not require lead time and that can achieve high effective throughput. The electron beam exposure apparatus comprises a beam source for generating an electron beam, shaping means for shaping the electron beam, deflecting means for changing the position of the electron beam irradiated on a sample, and projection means for focusing the shaped electron beam onto the sample, wherein the shaping means comprises splitting means for generating a plurality of sub-beams by splitting the electron beam, rectangular shaping means for respectively shaping each of the plurality of sub-beams into a desired rectangular shape, and sub-beam deflection means for respectively moving the irradiation position of each of the plurality of sub-beams. The electron beam exposure apparatus thus splits the electron beam generated by a single electron beam source into a plurality of sub-beams, applies shaping to each sub-beam using a variable size rectangle method, and deflects each shaped beam. If the axial distance between the sub-beams is small, the effects of the displacement between the sub-beams can be held small and the problem of displacements at joints does not occur. Moreover, all the sub-beams can be deflected over a wide range using prior known deflection means. As a result, the beam can be split into a large number of sub-beams, and the throughput improves greatly.

Title: Method of crystallizing a semiconductor thin film and producing a thin film semiconductor device
Inventor: HAYASHI HISAO
IPC: H01L29/786
Filed: 2000-07-13
Granted: 2001-08-21
Abstract: In crystallizing a semiconductor thin film of large area by overlapping regions of irradiation with a laser beam, the crystallinity of the film is made uniform. The semiconductor thin film is crystallized by performing the shaping step of shaping laser light emitted from a laser light source, thereby to define a laser beam which has a predetermined intensity distribution in a predetermined irradiation region, and the irradiating steps are repeatedly irradiating the semiconductor thin film formed over a substrate beforehand with the laser beam while scanning the film so that irradiation regions may be overlapped. On that occasion, the laser beam is shaped so that the sectional intensity distribution of the laser beam in the irradiating region as taken in the direction of the scanning may be convex, and that the peak of the intensity distribution may lie at a position which is between the front end and rear end of the irradiation region in relation to the scanning direction and which is nearer to the front end with respect to the middle of the irradiation region. Concretely speaking, the shaping step shapes the laser beam so that intensity at the front end of the irradiation region may become lower in a range within 30% as compared with the intensity of the peak. Also, the shaping step shapes the laser beam so that the intensity at the rear end of the irradiation region may become lower in a range exceeding 5%, as compared with the intensity of the peak.
