Patent ID: 7939813

Claim:
An e-beam exposure apparatus, comprising: an electron gun providing an e-beam for exposure to a resist layer formed on a substrate; an e-beam column part inducing the e-beam to be incident to the resist layer; and an electron collecting part introduced at the periphery of a path of the e-beam to absorb electrons scattered from a surface of the resist layer and thus inhibit the scattered electrons from being incident again onto the resist layer; wherein the electron collecting part includes: a plate body having a surface that opposes the surface of the resist layer; a plurality of electron inducing holes formed in the opposing surface, into which the scattered electrons enter; and an absorbing tunnel formed in the inside of the plate body so that the absorbing tunnel is perpendicularly connected to the electron inducing holes and the scattered electrons entering into the electron inducing holes collide with a wall of the absorbing tunnel to consume the kinetic energy.
