WebA lithographic tool needs to maintain the critical dimensions (CD) of the printed features within 10% variation typically over the field. One key parameter to CD control is the exposure energy, which will vary the dimension size. A second key parameter is the depth of focus (DOF) at the wafer. The exposure energy and DOF define the Web1 feb. 2011 · As part of ASML's holistic lithography roadmap, ASML is developing …
