Abstract:
An electron beam drawing method for drawing a figure on a surface of a sample comprising the steps of:forming an electron beam in a predetermined shape; if the figure dimension is greater than a scan length for the electron beam: performing a scan of the electron beam on the surface of the sample by turning the electron beam at a scan start point and a scan finish point until unexposed portion becomes smaller than the scan length; when the unexposed portion becomes smaller than the scan length cutting the beam at the turning point, repositioning the beam to an unexposed position to be irradiated, simultaneously with cutting the beam at the turning point using an irradiation deflector, and exposing said position to be irradiated; and, when the figure dimension to be exposed is smaller than the scan length: blanking the beam, setting the figure dimension with a forming deflector, releasing the blanking at a set position, and exposing the figure dimension.
