Patent ID: 8030625

Claim:
An electron beam writing method for writing a fine pattern on a substrate applied with a resist and placed on a rotation stage by scanning an electron beam on the substrate while rotating the rotation stage, the fine pattern including elements having a track direction length greater than an emission diameter of the electron beam, wherein: while rotating the substrate in one direction, ON/OFF control is performed with respect to the rotation of the substrate for emitting the electron beam at a predetermined rotational position of the substrate by a blanking-OFF signal, performing writing in a rotational direction of the substrate along with the rotation of the substrate, and terminating the writing by a blanking-ON signal based on write data of the fine pattern to perform writing for one round, and the writing based on the ON/OFF control is repeated by moving the electron beam or the substrate in a radial direction of the substrate, whereby the elements are written; and rotation control is performed for controlling the rotation speed of the rotation stage so as to be increased for inner track writing and decreased for outer track writing inversely proportional to the radius of the writing position in order to maintain the linear velocity of the rotation stage constant.
