1. A mask-less lithography system comprising:
- A converter comprising an array of light controllable electron sources, each electron source being arranged for converting light into an electron beam, each electron source having an activation area;
A plurality of individually controllable light sources, each light source arranged for activating one electron source;
Controller means for controlling each light source individually;
Focussing means for focussing each electron beam on an object plane and with a diameter smaller than the diameter of an individually controllable light source.

Abstract
The mask-less lithography system has a converter that includes an array of light controllable electron sources. Each electron source is arranged for converting light into an electron beam and has an activation area. Individually controllable light sources are included where each light source is arranged for activating one electron source. A Controller controls each light source individually and each electron beam is focused on an object plane with a diameter smaller than the diameter of an individually controllable light source.

17. A method of producing a pattern on a substrate, wherein data is retrieved from a data storage means on at least one computer system, said data representing the pattern to be produced on said substrate, said data is processed in said computer and converted into signals activating and deactivating individually controllable light sources, and said individually controllable light sources are projected on a converter comprising a plurality of electron sources arranged for converting light into an electron beam, each electron source having one activation area, each individually controllable light source producing a light spot on one activation area.

18. A direct write lithography system comprising:
-
A converter comprising an array of light controllable field emitters, each field emitter being arranged for converting light into an electron beam, the field emitters having an element distance between each two adjacent field emitters, each field emitter having an activation area;
A plurality of individually controllable light sources, each light source arranged for activating one field emitter;
Controller means for controlling each light source individually;
Focussing means for focussing each electron beam from the field emitters with a diameter smaller than the diameter of a light source on an object plane.
