摘要:
The invention relates to lithography techniques and more particularly to template-free lithography in which a pattern is directly written on a substrate using an energetic beam, typically a laser beam. According to the invention, the position of the beam is moved according to a continuous movement relative to the surface of the substrate, and the beam is switched on or off depending on the pattern to be written on the substrate. The pattern is such that the smallest width of the areas to be radiated is larger than the smallest width (L, L1) of the areas (8) that must be radiated. The active diameter (D) of the radiation beam is larger than the latter. The diameter is defined based on the depth of the resin to be exposed and is a compromise between the need or depth exposure and the size of the patterns to be written. It is thus possible to achieve a resolution higher than that theoretically possible with the beam diameter, even for resins having a thickness which is much higher than the size of the finest patterns to be produced.
