The invention relates to a novel method for producing microhole structures. According to said method, the material used to produce said microhole structures is applied to a substrate surface provided with a relief structure, by means of an angular coating process. In order to achieve the desired pattern of holes, the relief structure has a continuous network of first surface elements and second surface elements located thereinbetween, the local surface normal vectors of the first surface elements forming a small angle with the unit vector, and the local surface normal vectors of the second surface elements forming a small angle with the direction vector of the coating.
