摘要: A device or chuck for fixing thin and/or flexible substrates allows a uniform and all-over sucking-up of the substrates without any disadvantageous warping or bending. The chuck has notches and holes communicating with a plurality of microgrooves arranged on the bearing surface. If a vacuum device sucks off air through the bores and the notches, a vacuum extends in the microgrooves so that a substrate located on the bearing surface is sucked up.
