  • Patent number: 10763151
    Abstract: A wafer carrier comprises a first foil, a second foil, and a chamber between the first and the second foil. The first foil has a perforation and is used for carrying the wafer. The first and the second foil are connected to each other so as to form the chamber. The chamber is configured to be evacuated to form a vacuum in the chamber, the vacuum causes an underpressure at the perforation, the underpressure forms a carrying force to the wafer to be carried.
