In order to create a lithography exposure device for producing structures extending in a surface area in a light-sensitive layer, with which a radiation field can be generated in the light-sensitive layer and with a control for controlling the intensity and position of the radiation field in such a manner that by means of a large number of successive exposure steps a plurality of conversion areas can be generated, in which the material of the light-sensitive layer is converted from an initial state into an end state and which together result in the structures, with which it is possible to produce, without masks, structures which have in at least one direction an extension which is smaller than that of one of the radiation fields used, it is suggested that with at least some of the exposure steps the control generate radiation fields with a distribution of energy which makes the action of at least two radiation fields on the same conversion area necessary in order to transfer the material of the light-sensitive layer in this area into the converted end state.

An image is produced in an image plane using a row of semiconductor laser emitters which provide a corresponding row of outlet spots as light sources. An optical projection system receives radiation from the outlet spots and the radiation on the image plane as one or more rows of images by virtue of the illumination of individual, adjacently located imaging spots. The optical projection system associates at least one outlet spot with each of the imaging spots, and simultaneously forms the image of the outlet spots of all of the semiconductor laser emitters of the row of light sources at the imaging spots associated therewith.

A laser radiation source is provided with an array of N individual slave laser diodes in a predetermined surface area. Adjustable power supply networks enable adjustment of the slave laser diodes relative to one another for operation in a stable manner. The slave power supply has a separate power supply network for each slave laser diode. Each of the power supply networks can be adjusted with respect to the current supplied to the respective slave laser diode during a certain operating period. This enables adjusting the slave laser diodes relative to one another. The power supply networks can be connected in parallel and supplied by a common source.

In order to improve a laser system comprising a fiber bundle consisting of single mode fibers which form with a first end a fiber bundle end, at which a total radiation field, which can be imaged onto a target surface, is formed from laser radiation exiting from the first ends of the fibers, and which are coupled with a second end to a subsystem generating the laser radiation with at least one semiconductor laser, such that this also operates efficiently with semiconductor lasers or semiconductor laser amplifiers and can be realized in an inexpensive manner it is suggested that the subsystem comprise a plurality of semiconductor laser units operating parallel, that all the semiconductor laser units of the subsystem operate with the same wavelength in a phase-balanced manner relative to one another as a result of master laser radiation coupled into them and that individual laser radiation exiting from the individual semiconductor laser units of the respective subsystem be combined by means of a coupling device of the respective subsystem to form a coherent laser radiation field which can be coupled into one of the single mode fibers.

A lithography exposure device allows more effective production of small structures within a short time by lithography. The device includes a retainer for a substrate, an exposure unit for producing a light spot on the light-sensitive layer of the substrate, a motion unit for producing apparent motion between the exposure unit and the retainer, and a control unit for controlling the intensity and position of the light spot on the light-sensitive layer. The exposure unit has several solid-state lasers, and a focusing unit that guides the laser beam of each solid-state laser to a light spot of a defined light spot pattern. The entire light spot pattern and the retainer are displaceable relative to each other in an exposure motional direction. Moreover, the light spots of the light spot pattern which correspond to the form of the partial areas to be exposed can be activated or deactivated.
