Abstract
A medical device with structure elements is made by providing a substrate; optionally depositing a layer of a sacrificial material on the substrate; and applying of a photoresist layer to the substrate. The layer of sacrificial material and structuring of the photoresist layer according to the shape of the structure elements are produced such that first free spaces are formed which are open on the side facing away from the substrate and are delimited by side faces of the photoresist layer. An angle is set between the side faces and the substrate. Sacrificial material is deposited in the first free spaces so first mask elements from sacrificial material are adapted to the inner contour of the first free spaces. The photoresist layer is removed so that second free spaces are formed between the first mask elements.
