  • Patent number: 7880152
    Abstract: The invention relates to a device and a method for producing resist profiled elements. According to the invention, an electron beam lithography system is used to produce an electron beam, the axis of the beam being essentially perpendicular to a resist layer in which the resist profiled element is to be produced. The electron beam can be adjusted in terms of the electron surface dose in such a way that a non-orthogonal resist profiled element can be produced as a result of the irradiation by the electron beam.
