And methods that involve such a lithographic apparatus suitable for lithographic a complementary e-beam lithography (CEBL) they are described. In the example, e-beam and micro-alignment of the tool includes the step of moving the wafer in the Y direction while projecting an electronic image of the plurality of apertures in the X-direction alignment features over e-beam column of the wafer. The method comprises the steps of detecting the time of the decomposition and back-scattered electrons (BSE) detection response waveform during the projection also. The method also includes determining the X position of all edges of all features in the X-direction alignment feature by calculating the derivative of the BSE detection response waveform. The method includes the step of adjusting the alignment of the e-beam column for after determining the X position of all edges of all features in the X-direction alignment features, the wafer also.
