Abstract

The invention relates to a method for displaying a pattern on a resist using electron lithography. In particular, a cathode device having a matrix of semiconductor cathodes generates an electron beam which exposes a resist layer. The electron beam is generated by applying control signals to selected ones of the matrix of cathodes to cause electron emission therefrom.
