    • A significant improvement in the alignment of a particle-beam-generated pattern relative to a pre-existing pattern present on a substrate has been accomplished using optical measurement to register the particle beam to the pre-existing pattern. Use of a position fiducial which can be accurately measured by both an optical microscope and a particle beam axis is used to align a pre-existing pattern with a particle-beam-generated pattern during writing of the particle-beam-generated pattern. Registration of the pre- existing pattern to the fiducial and registration of the particle beam axis to the fiducial periodically during production of the particle-beam-generated pattern continually provides an improvement in the overall alignment of the pattern being created to the pre-existing pattern on the substrate. The improved method of alignment can be used to correct for drift, or thermal expansion, or gravitational sag, by way of example.
    • 已经使用光学测量来完成粒子束产生的图案相对于衬底上存在的预先存在的图案的对准的重大改进,以将粒子束注册到预先存在的图案 。 在写入粒子束产生的图案期间,使用可以通过光学显微镜和粒子束轴精确测量的位置基准来将预先存在的图案与粒子束生成图案对齐。 将预先存在的图案配准到基准上并且在生成粒子束生成图案期间周期性地将粒子束轴配准到基准提供了对正在创建的图案与预先存在的图案的整体对准的持续改进 在衬底上。 举例来说,改进的对准方法可用于校正漂移,热膨胀或重力下垂。

    • 已经使用光学测量来实现粒子束生成图案相对于存在于衬底上的预先存在的图案的对准的显着改进,以将粒子束注册到预先存在的图案。 使用可以通过光学显微镜和粒子束轴两者精确测量的位置基准来使用在粒子束产生的图案的写入期间将预先存在的图案与粒子束产生的图案对准。 在生成粒子束生成图案期间,将预先存在的图案注册到基准和粒子束轴的基准周期性地连续地提供了所创建的图案与预先存在的图案的整体对准的改进 在基板上。 改进的对准方法可以用于校正漂移或热膨胀或重力下垂的例子。
