Abstract (en)

[origin: WO0050665A1] According to the inventive method, a photosensitive layer (4) is mounted on the inner surface (3) of the borehole (1). Said layer (4) is exposed according to an exposure pattern (8) that corresponds to the desired arrangement of the groove/s (12). Sections of the photosensitive layer (4) are selected by the exposure pattern (8) and are removed by means of photochemical development. An etching agent is inserted into the borehole (1) in order to etch the borehole sections which are not covered by the photosensitive layer (4). The remaining sections of the photosensitive layer (4) are removed.
