Abstract:
A method of manufacturing a semiconductor device having a semiconductor body (11) comprising a monocrystalline semiconductor substrate (32) of silicon the surface of which has a crystal orientation, in which semiconductor substrate a semiconductor element (10) is formed, and the surface of the semiconductor body (11) is covered with a mask pattern (40), after which a part (50) of the semiconductor body (11) is removed by means of powder blasting, characterized in that the (111) crystal orientation is chosen as the crystal orientation of the substrate (32), and the longitudinal direction (M) of the mask pattern (40) is aligned with respect to the (111) crystal orientation (L) of the substrate (32) in such a way that the removed part (50) of the semiconductor body (11) has a symmetric profile when viewed in cross-section.
