  • Patent number: 10872802
    Abstract: In a method of debonding a carrier substrate from a device substrate, an ultraviolet (UV) light may be irradiated to an adhesive tape through the carrier substrate, which may be attached to a first surface of the device substrate having a connection post using the adhesive tape, to weaken an adhesive force of the adhesive tape. An outskirt portion of the carrier substrate may be masked to concentrate the UV light on the adhesive tape.

  • Patent number: 10756062
    Abstract: A semiconductor chip includes a semiconductor substrate, a through electrode, an inter-mediation pad, an upper pad, and a rewiring line. The semiconductor substrate includes a first surface that is an active surface and a second surface that is opposite to the first surface. The through electrode penetrates the semiconductor substrate and is disposed in at least one column in a first direction in a center portion of the semiconductor substrate. The inter-mediation pad is disposed in at least one column in the first direction in an edge portion of the second surface. The upper pad is disposed on the second surface and connected to the through electrode. The rewiring line is disposed on the second surface and connects the inter-mediation pad to the upper pad.
