  • Patent number: 11683882
    Abstract: A device for manufacturing a stretchable substrate structure according to an embodiment includes a carrier substrate receiving portion configured to receive a carrier substrate therein, a stretchable substrate receiving portion configured to receive a stretchable substrate in a direction facing the carrier substrate, and a diaphragm configured to be deformed by air pressure provided on one surface, wherein the diaphragm comes in contact with an entire surface of the stretchable substrate in a plane direction when deformed, such that the stretchable substrate is combined to the carrier substrate by deforming according to the deformed shape of the diaphragm.
