  • Carbon tape intended to receive a layer of a semiconductor material
    Patent number: 8609520
    Abstract: A carbon ribbon (16) has two faces (20, 22) and two longitudinal ends (34, 36), at least one of the faces of the ribbon (16?) having a central portion (20a, 22a) situated between the two longitudinal ends (34, 36), which central portion is to receive a deposit of a layer of a semiconductor material (30, 32). The ribbon further includes, on at least one of its races (20, 22), at least one longitudinal groove (17) situated between one of said ends (34, 36) and the central portion (20a, 22a), and in that the longitudinal groove (17) is shaped in such a manner that when the layer of the semiconductor material is deposited, the semiconductor material (30, 32) filling the groove (17) forms a protuberance (31) adjacent to one of the longitudinal ends (34, 36) of one of the faces (20, 22) of the carbon ribbon.
