  • Patent number: 8137417
    Abstract: An object is to eliminate electric discharge due to static electricity generated by peeling when an element formation layer including a semiconductor element is peeled from a substrate used for manufacturing the semiconductor element. A substrate over which an element formation layer and a peeling layer are formed and a film are made to go through a gap between pressurization rollers. The film is attached to the element formation layer between the pressurization rollers. The film is bent along a curved surface of the pressurization roller on a side of the pressurization rollers, where the film is collected, and accordingly, peeling is generated between the element formation layer and the peeling layer and the element formation layer is transferred to the film.

  • Patent number: 8138589
    Abstract: In fabrication of a semiconductor device mounted on a wiring board, a semiconductor circuit portion is formed over a glass substrate. Then, an interposer having connection terminals are bonded to the semiconductor circuit portion. After that, the glass substrate is peeled off from the semiconductor circuit portion, and a mold resin is poured to cover the periphery of the semiconductor circuit portion from a direction of the separation plane. Then, the mold resin is heated under predetermined conditions to be hardened.

  • Publication number: 20120045861
    Abstract: An object is to suppress discharge due to static electricity generated by peeling, when an element formation layer including a semiconductor element is peeled from a substrate. Over the substrate, the release layer and the element formation layer are formed. The support base material which can be peeled later is fixed to the upper surface of the element formation layer. The element formation layer is transformed through the support base material, and peeling is generated at an interface between the element formation layer and the release layer. Peeling is performed while the liquid is being supplied so that the element formation layer and the release layer which appear sequentially by peeling are wetted with the liquid such as pure water. Electric charge generated on the surfaces of the element formation layer and the release layer can be diffused by the liquid, and discharge by peeling electrification can be eliminated.

  • Patent number: 8058083
    Abstract: It is an object of one embodiment of the preset invention to conduct separation without damaging a semiconductor element when the semiconductor element is made flexible. Further, it is another object of one embodiment of the preset invention to provide a technique for weakening adhesion between a separation layer and a buffer layer. Furthermore, it is another object of one embodiment of the preset invention to provide a technique for preventing generation of the bending stress on a semiconductor element due to separation. A semiconductor element formed over a separation layer with a buffer layer interposed therebetween is separated by dissolving the separation layer by using an etchant. Alternatively, separation is conducted by inserting a film into a region where a separation layer is dissolved by being in contact with an etchant and moving the film in a direction toward a region where the separation layer is not dissolved.
