  • Publication number: 20250120179
    Abstract: An object is to provide a semiconductor device having a structure with which parasitic capacitance between wirings can be sufficiently reduced. An oxide insulating layer serving as a channel protective layer is formed over part of an oxide semiconductor layer overlapping with a gate electrode layer. In the same step as formation of the oxide insulating layer, an oxide insulating layer covering a peripheral portion of the oxide semiconductor layer is formed. The oxide insulating layer which covers the peripheral portion of the oxide semiconductor layer is provided to increase the distance between the gate electrode layer and a wiring layer formed above or in the periphery of the gate electrode layer, whereby parasitic capacitance is reduced.

  • Patent number: 12269079
    Abstract: A rolling mill includes three or more rolling rolls aligned along a circumferential direction and arranged so each rotary shaft is skewed with respect to a pass line of a material to be rolled, wherein the material to be rolled made of a pipe or bar material passes between the rolling rolls while being rotated to undergo diameter reducing rolling. At least one rolling roll selected from the three or more rolling rolls is smaller in roll diameter than at least one other rolling roll. When at least one rolling roll having a relatively maximum roll diameter defined as a maximum diameter rolling roll and at least one rolling roll smaller in roll diameter than the maximum is defined as a small diameter rolling roll, the small diameter rolling roll has a roll diameter equal to or less than 90% of the roll diameter of the maximum diameter rolling roll.

  • Publication number: 20250062121
    Abstract: An object is to provide a high reliable semiconductor device including a thin film transistor having stable electric characteristics. In a method for manufacturing a semiconductor device including a thin film transistor in which an oxide semiconductor film is used for a semiconductor layer including a channel formation region, heat treatment (which is for dehydration or dehydrogenation) is performed so as to improve the purity of the oxide semiconductor film and reduce impurities such as moisture. Besides impurities such as moisture existing in the oxide semiconductor film, heat treatment causes reduction of impurities such as moisture existing in the gate insulating layer and those in interfaces between the oxide semiconductor film and films which are provided over and below the oxide semiconductor film and are in contact with the oxide semiconductor film.

  • Patent number: 12227586
    Abstract: An object of the present invention is to provide an anti-CLDN4/anti-CD137 bispecific antibody usable in treatment of cancer. An anti-CLDN4/anti-CD137 bispecific antibody produced using an anti-CLDN4 antibody binding to CLDN4 and an anti-CD137 antibody binding to CD137 had agonistic activity for CD137, promoted production of interferon ? by a T cell, and exhibited cytotoxic activity against a cancer cell expressing CLDN4 on a cell surface thereof. Besides, it was shown that the anti-CLDN4/anti-CD137 bispecific antibody can be safely administered to monkeys. Therefore, the anti-CLDN4/anti-CD137 bispecific antibody is usable in treatment of human cancer.

  • Publication number: 20240166736
    Abstract: An objective of the present invention is to provide an anti-TSPAN8/anti-CD3 bispecific antibody and an anti-TSPAN8 antibody usable in treatment or prevention in human. A human monoclonal antibody producing mouse was immunized with a peritoneal disseminated cancer cell isolated from a patient, to obtain an antibody 16B11 and an antibody 16B12 that selectively bind to a peritoneal disseminated cancer cell. These antibodies were anti-TSPAN8 antibodies that bind to the region from amino acid positions 126 to 155 of TSPAN8 and exhibited strong binding activity to TSPAN8 expressed in the peritoneal disseminated cancer cell. Further, an anti-TSPAN8(16B11)-anti-CD3 bispecific antibody produced based on the sequence of 16B11 exhibited a cytotoxic activity against the TSPAN8-expressing cancer cell in vitro, exerted an anti-tumor action on TSPAN8-expressing cancer cell-bearing mice in vivo, and extended the lifetime of peritoneal dissemination model mice.

  • Patent number: 11736830
    Abstract: A solid-state imaging element includes a pixel and an image processing unit. The pixel has a common transistor, a charge accumulation unit, and a power supply. The common transistor has a first terminal and a second terminal. The common transistor maintains a voltage of the first terminal at a predetermined voltage with a voltage applied from the power supply and outputs a voltage corresponding to a change in a voltage of the charge accumulation unit from the second terminal, based on a condition that an element voltage is a ground voltage. The common transistor outputs a voltage corresponding to a change in a voltage of the charge accumulation unit from the first terminal, based on the element voltage is higher than the ground voltage. The image processing unit generates a luminance image according to a change in the voltage output from the second terminal of the common transistor.
