摘要： A rough pattern exceeding the resolution limit of light exposure is formed by light resolution. A fine pattern not exceeding the resolution limit of light exposure is formed by charge-beam exposure. Combining the rough pattern and the fine pattern produces a desired pattern. The sharing of the work between light exposure and charge-beam exposure exhibits the high throughput of light exposure and the excellent resolving power of charge-beam exposure.

摘要： A charged beam lithography apparatus simultaneously uses multiple charged beams to irradiate a workpiece. In specific embodiments, collimators are employed to assist in aligning the multiple charged beams by eliminating "noise" from reflections of other beams. Each collimator is positioned to correspond with respective of the charged beams and detectors for detecting reflected particles from the charged beams. The particles are reflected from particular marks used in the alignment process. Each collimator helps to prevent particles from adjacent charged beams from entering a detector that corresponds with a specific charged beam.
