The invention relates to an evaporation boat comprising an evaporator body, wherein the evaporator body comprises an evaporator surface which extends along a longitudinal direction of the evaporator body. The evaporator surface has a pyramidally structured surface which can be created by mechanically machining the evaporator surface in two mutually perpendicular machining directions. The pyramidally structured surface comprises a plurality of structural elements which are directly adjacent to one another and have a substantially rectangular bottom surface and lateral surfaces which taper conically to a top surface or point.
