Patent ID: 8653488

Claim:
An electron beam lithography apparatus in which a substrate is mounted on a stage that is driven to rotate and move translationally and which performs drawing by switching between irradiation and non-irradiation of an electron beam on said substrate by means of deflection of the electron beam according to drawing data, said lithography apparatus comprising: a beam current detector configured to detect, during drawing of said drawing data, fluctuation of an irradiation position of said electron beam at non-irradiation on said substrate; a beam position error detector configured to detect a beam position error of said electron beam based on the fluctuation of the irradiation position; a drive position error detector configured to detect a drive position error of said stage due to rotation and translation drive during drawing of said drawing data; and a corrector configured to correct the irradiation position of said electron beam during the drawing based on said beam position error and said drive position error; wherein the beam current detector is located upstream of substrate and the substrate stage.
