  • Photosensitive resin composition, method for manufacturing cured resin film, and semiconductor device
    Patent number: 10365559
    Abstract: Provided is a photosensitive resin composition containing: one or more kinds of alkali-soluble resins selected from a polyimide, a polybenzoxazole, a polyimide precursor, a polybenzoxazole precursor, and a copolymer formed of two or more polymers selected from the preceding substances; and a photosensitizer. The photosensitive resin composition further contains a compound represented by general formula (1). Even when a cured film is fired at low temperature, the photosensitive resin composition exhibits superior adhesion properties with metallic materials, particularly copper, and also exhibits high chemical resistance.
    Type: Grant
    Filed: February 9, 2016
    Date of Patent: July 30, 2019
    Assignee: TORAY INDUSTRIES, INC.
    Inventors: Yukari Arimoto, Yuki Masuda, Ryoji Okuda

  • Polyimide precursor, polyimide resin film produced from said polyimide precursor, display element, optical element, light-receiving element, touch panel and circuit board each equipped with said polyimide resin film, organic EL display, and methods respectively for producing organic EL element and color filter
    Patent number: 9828469
    Abstract: The present invention provides a polyimide precursor that serves to produce a cured film that has high light permeability in combination with low birefringence and low linear thermal expansion. The polyimide precursor includes at least an acid dianhydride residue as represented by Formula (1), a diamine residue as represented by Formula (2), and one or more diamine residues as represented by Formula (3), the acid dianhydride residue as represented by Formula (1) accounting for 50 mol % or more of the total quantity of acid dianhydride residues in the polyimide precursor, the diamine residue as represented by Formula (2) accounting for 50 mol % or more of the total quantity of diamine residues in the polyimide precursor, and the diamine residue as represented by Formula (3) accounting for 15 mol % or less of the total quantity of diamine residues in the polyimide precursor.
