PROCEDURAL ELECTRON BEAM LITHOGRAPHY

A Procedural EBL system implements a user-provided oracle function (e.g., associated with a specific pattern) to generate control instructions for electron beam drive electronics in an on-demand basis. A control system may invoke the oracle function to query the pattern at individual point locations...

Zusammenfassung:	A Procedural EBL system implements a user-provided oracle function (e.g., associated with a specific pattern) to generate control instructions for electron beam drive electronics in an on-demand basis. A control system may invoke the oracle function to query the pattern at individual point locations (e.g., individual x,y locations), and/or it may query the pattern over an area corresponding to a current field being addressed by the beam and stage positioner, for example. This Procedural EBL configuration manages control and pattern generation so that the low-level drive electronics and beam column may remain unchanged, allowing it to leverage existing EBL technologies.
