Electron beam exposure system

Номер: CN0101414124B
Принадлежит:

The invention relates to an electron beam exposure apparatus for transferring a pattern onto the surface of a target (14), comprising: a beamlet generator for generating a plurality of electron beamlets (5a, 5b); a modulation array for receiving said plurality of electron beamlets, comprising a plurality of modulators for modulating the intensity of an electron beamlet; a controller, connected tothe modulation array for individually controlling the modulators, an adjustor, operationally connected to each modulator, for individually adjusting the control signal of each modulator; a focusing electron optical system comprising an array of electrostatic lenses (7) wherein each lens focuses a corresponding individual beamlet, which is transmitted by said modulation array, to a cross section smaller than 300 nm, and a target holder for holding a target with its exposure surface onto which the pattern is to be transferred in the first focal plane of the focusing electron optical system.
