1. A method of manufacturing a semiconductor device (1) with a semiconductor body (2), in which method a doped region (3) is formed in the semiconductor body (2), which semiconductor body (2) comprises a crystalline semiconducting surface region (4) of semiconductor material, while at least a portion of the crystalline semiconducting surface region (4) is amorphized so as to form an amorphous surface layer (5), characterized in that the amorphization is carried out through irradiation of the surface (6) with a radiation pulse (7) having a wavelength whereby radiation of the radiation pulse is absorbed by the crystalline surface region (4), and having energy flux whereby the crystalline surface layer (5) is melted.
