Patent number: 11919300Abstract: An inkjet printing apparatus adopting short pulse heating is designed to output a uniform image without unevenness. To this end, in a serial inkjet printing apparatus, a print head is subjected to a short pulse heating treatment before each print scan is carried out. In a case where a print medium is a first print medium, the print head is heated to a first target temperature before carrying out each of the print scans. In a case where the print medium is a second print medium, the print head is heated to a second target temperature lower than the first target temperature before carrying out each of the print scans.Type: GrantFiled: March 15, 2021Date of Patent: March 5, 2024Assignee: Canon Kabushiki KaishaInventors: Hiroshi Kawafuji, Kazuhiko Sato, Kazuo Suzuki, Takeshi Murase, Hiroshi Taira, Tomoki Yamamuro, Sae Mogi, Masaki Nitta

Patent number: 8062548Abstract: An object of one embodiment of the present invention is to provide a polishing slurry which can reduce dishing and erosion of a to-be-polished semiconductor wafer. The polishing slurry contains an oxidizing agent and two or more kinds of abrasive grains for polishing, i.e., fumed silica and colloidal silica. A ratio (selectivity ratio) between a polishing rate of a metal film such as a tungsten film and a polishing rate of an insulating film (oxide film) such as a SiO2 film can be adjusted by changing a mixing ratio between fumed silica and colloidal silica, and dishing and erosion of the semiconductor wafer can be thus reduced.Type: GrantFiled: January 5, 2006Date of Patent: November 22, 2011Assignee: Nitta Haas IncorporatedInventors: Yoshiharu Ohta, Rika Tanaka, Hiroshi Nitta, Yoshitaka Morioka

Publication number: 20100207058Abstract: At least one embodiment of the invention provides a polishing composition that can achieve high polishing rate and as well can improve flatness. The polishing composition of at least one embodiment of the invention is a polishing composition suitable for a metal film, particularly a copper (Cu) film, and contains a basic compound containing an ammonium group, alkyl naphthalene sulfonate and hydrogen peroxide, the remainder being water. The pH of the polishing composition is within a range of 8 to 12. By containing those, a polishing composition that can achieve high polishing rate and improve flatness can be realized.Type: ApplicationFiled: August 25, 2008Publication date: August 19, 2010Inventors: Yoshiyuki Matsumura, Hiroshi Nitta

Publication number: 20100207057Abstract: An object of one embodiment of the present invention is to provide a polishing composition which suppresses generation of recessing and dishing and includes a higher polishing rate. The polishing composition of an embodiment of the invention is a polishing composition suitable for a metal film, particularly a copper (CU) film, and contains ammonia, hydrogen peroxide, an amino acid and an anionic surfactant, the remainder being water. By containing those, the polishing composition can suppress generation of recessing and dishing when particularly used in the second step polishing.Type: ApplicationFiled: August 25, 2008Publication date: August 19, 2010Inventors: Hiroshi Nitta, Yoshiyuki Matsumura

Patent number: 7767426Abstract: A method of producing riboflavin by culturing riboflavin-producing microbes in a culture medium using a plant oil or an animal oil as a carbon source, forming and accumulating riboflavin therein and collecting riboflavin therefrom, wherein a carrier of a clay mineral having oil-adsorbing property, a chemically treated product thereof or a calcium compound is made present in the culture medium. The riboflavin is produced maintaining a high yield and at an increased production rate at a low cost without requiring cumbersome operations for concentrating and recovering the riboflavin. It is further allowed to recover the riboflavin by effectively utilizing the waste plant oil or the waste animal oil that is to be disposed of.Type: GrantFiled: February 18, 2003Date of Patent: August 3, 2010Assignee: Mizusawa Industrial Chemicals, Ltd.Inventors: Kiyoshi Abe, Hiroshi Nitta, Enoch Y. Park, Hua Ming, Eun He Jung
