Abstract:
1. A method of manufacturing at least a first semiconductor chip, comprising: providing a middle layer between a substrate and a carrier to combine the carrier with the substrate; thinning the substrate; and after thinning the substrate, separating the carrier from the substrate; after the carrier is separated from the substrate, cutting the substrate to form at least the first semiconductor chip, wherein the middle layer is adhered to the carrier with a first bonding force, and the middle layer is adhered to the substrate with a second bonding force, wherein the second bonding force is greater than the first bonding force, wherein the middle layer includes an adhesion layer in contact with a release layer, the adhesion layer being in contact with the substrate and the release layer being in contact with the carrier, wherein the first bonding force is between the release layer and the adhesion layer, in the second bonding force is between the adhesion layer and the substrate, wherein the substrate includes a first ,surface on which an integrated circuit is formed, and a second surface opposite to the first surface, and wherein the middle layer is provided between the first the substrate and a first surface of the carrier that faces the first surface of the substrate, and the adhesion layer is adhered to the first surface of the substrate, and further comprising, before separating the carrier from the substrate: providing a second carrier on the second surface of the substrate, with a second middle layer therebetween to adhere the second carrier with the substrate, wherein the second middle layer is adhered to the second carrier with a third bonding force, and the second middle layer is adhered to the substrate with a fourth bonding force, wheren the fourth bonding force is greater than the third bonding force, wherein the second middle layer includes a second adhesion layer contacting the second surface of the substrate, and a second release layer contacting the adhesion layer and the second carrier, and wherein the third bonding force is between the second release layer and the second adhesion layer, and the fourth bonding force is between the second adhesion layer and the substrate.
