Patent ID: 6859261

Claim:
A lithography exposure device for producing exposed structures extending in a surface area of a light-sensitive layer, comprising: a mounting device for the light-sensitive layer, an exposure unit comprising several laser radiation sources, an optical focusing means associated with the laser radiation sources for laser radiation exiting the respective laser radiation sources, said optical focusing means generating from the laser radiation of each of the laser radiation sources an exposure spot effective in the light-sensitive layer with a predetermined extension transverse to an exposure movement direction, a movement unit for generating a relative movement between the optical focusing means and the mounting device in the exposure movement direction, a control for controlling intensity and position of the exposure spots relative to the light-sensitive layer in such a manner that a plurality of conversion areas is generatable in the light-sensitive layer by means of the exposure spots, the material of the light-sensitive layer being converted in said areas from an initial state into the exposed state and said areas together resulting in the exposed structure, said exposure spots when undeflected being arranged at a certain transverse distance with respect to each other in a direction transverse to the exposure movement direction, said certain transverse distance between said exposure spots being greater than said predetermined extension of said exposure spots a controllable deflection device being provided between the laser radiation sources and the optical focusing means for the movement of the exposure spot in the deflection direction extending transverse to the exposure movement direction, said controllable deflection device being adapted to enable generation of all the conversion areas located within a strip area due to movement of the exposure spot in a deflection direction, said strip area extending in the exposure movement direction and having transversely to the exposure movement direction a width amounting to a greater extent than the extension of the exposure spot in this direction.
