Abstract
The invention relates to a substrate carrier for holding substrates, especially semiconductor wafers. Good sealing of the wafer surface and electrical contact are made possible in that the substrate carrier has a first and a second part having a central opening matching the form of the substrate, wherein the substrate is received between the first and the second part and a peripheral seal having at least one undercut is provided in the inner periphery of the second part.
