  • Patent number: 8349645
    Abstract: A mask includes: a tabular first section which includes a side portion and an opening portion formed at a position corresponding to a film formation region of a substrate and on which the substrate is to be disposed so that the first section overlaps a face of the substrate on which a film is to be formed; and a second section which is provided along the side portion of the first section, and covers at least one of portions of a side face of the substrate, wherein second sections of two adjacent masks overlap each other and a superposed section is thereby formed when a plurality of masks are arrayed in a lateral direction thereof.
    Type: Grant

  • Patent number: 8198115
    Abstract: A method for manufacturing a solar cell, includes: forming, on a silicon substrate whose conductivity type is p-type or n-type, a silicon layer including a dopant whose conductivity type is different from that of the silicon substrate; and diffusing the dopant included in the silicon layer into the silicon substrate by heat-treating the silicon layer.

  • Publication number: 20110162710
    Abstract: A solar cell includes: a photoelectric converter in which a first electrode layer, a photoelectric conversion layer, and a second electrode layer are stacked on a substrate in order; and a texture layer that is disposed between the substrate and the first electrode layer, made of a transparent material in a visible light region, and has a continuous irregular configuration on a face that is in touch with the first electrode layer.

  • Publication number: 20110120553
    Abstract: A method for manufacturing a solar cell, includes a scribing step in which grooves electrically-separating a photoelectric converter into a plurality of compartment sections are formed after the photoelectric converter is formed on a substrate by stacking a first-electrode layer, a photoelectric conversion layer, and a second-electrode layer in this order; a first groove, a second groove, a third groove, and a fourth groove are formed in the scribing step; the method including an insulating-layer forming step in which an insulating layer is formed after the scribing step and a wiring layer forming step in which a wiring layer is formed; the wiring layer passes from the first-electrode layer that is exposed at a bottom face of the second groove, through the inside of the second groove and a surface of the insulating layer, to a surface of the second-electrode layer that is disposed so as to be lateral to the fourth groove opposite to the second groove; and the wiring layer electrically connects the plurality o

  • Patent number: 7935232
    Abstract: To provide a sputtering apparatus and method, and a sputtering control program which are configured simply and can secure the uniformity of the film thickness from the beginning to the end of the use of a target. There are provided: a target 15 disposed so as to face an object to be treated 19; a permanent magnet unit M which generates a high-density plasma by means of a magnetic field and deposits a material of the target 15 on the object to be treated, in the form of a film; a rotational mechanism 9 which rotates the permanent magnet unit M; and a rotation number control apparatus 7 which gradually changes the number of rotations of the permanent magnet unit M rotated by the rotational mechanism 9.
