  • Patent number: 11966164
    Abstract: A method produces a semiconductor device, the method having a step of transferring an underlayer by employing a resist underlayer film-forming composition containing a hydrolysis condensate prepared through hydrolysis and condensation of a hydrolyzable silane in a non-alcoholic solvent in the presence of a strong acid, followed by a step (G) of removing the patterned resist film, the patterned resist underlayer film, and/or particles with a sulfuric acid-hydrogen peroxide mixture (SPM) prepared by mixing of aqueous hydrogen peroxide with sulfuric acid and/or an ammonia-hydrogen peroxide mixture (SC1) prepared by mixing of aqueous hydrogen peroxide with aqueous ammonia, wherein: the hydrolyzable silane contains a hydrolyzable silane of the following Formula (1): R1aR2bSi(R3)4?(a+b)??Formula (1) (wherein R1 is an organic group having a primary amino group, a secondary amino group, or a tertiary amino group and is bonded to a silicon atom via an Si—C bond).

  • Patent number: 11383378
    Abstract: A grasping apparatus 1 includes: an image data acquisition unit 16; a robot arm 11; a control unit 12; and a grasping position determination unit 18 configured to determine, using the image data of photographed flexible objects in a folded and stacked state that is acquired by the image data acquisition unit 16, whether or not a part of the flexible objects in that image data is suitable for being grasped. The control unit 12 controls the robot arm 11 so as to deform ends of a top surface of the flexible object at the top of the stacked flexible objects. The grasping position determination unit 18 determines whether or not a part is suitable for being grasped using the image data of the photographed flexible object the ends of the top surface of which have been deformed.
