Patent ID: 7829863

Claim:
An electron beam irradiation device, comprising: a light pattern generating section for generating a two-dimensional light pattern; an electron amplification section for (i) generating an electron beam array based on the light pattern entered, (ii) amplifying the electron beam array, and (iii) emitting the electron beam array as an amplified electron beam array, wherein said electron amplification section includes multiple cylindrical microchannels which are arranged adjacent to one another in a direction perpendicularly crossing a direction of a light axis of the light pattern so that respective axes of the microchannels are parallel to the direction of the light axis; an electron beam lens section for converging the amplified electron beam array on an electron ray resist; and a controller for controlling the light pattern generating section so as to generate, in a time-sharing manner, multiple divided light patterns which compensate one another, from the light pattern entering the microchannels.
