  • Patent number: 8354326
    Abstract: Structures and methods for precision trench formation are disclosed. In one embodiment, a method for manufacturing a semiconductor device comprises forming a first oxygen-containing region in a semiconductor substrate by performing an oxygen ion implantation to a portion of the semiconductor substrate, and oxidizing the first oxygen-containing region using oxygen contained therein by performing a thermal processing to the semiconductor substrate, where the first oxygen-containing region is converted to a first oxide region. The method further comprises forming a groove in the semiconductor substrate by eliminating the first oxide region, where the performing thermal processing comprises subjecting the first oxygen-containing region to a gas low on oxygen.

  • Patent number: 8088802
    Abstract: An N-phenylarylsulfonylamide compound of formula (I) (R1 is COOH etc.; R2 is hydrogen, methyl, etc.; R3 and R4 are a combination of methyl and methyl, etc.; R5 is isopropyl etc.; Ar is thiazolyl, pyridyl, 5-methyl-2-furyl each optionally substituted with methyl; n is zero or 1), a synthetic intermediate for the compound and a process for its preparation. The compound of formula (I) binds to a prostaglandin E2 receptor, especially an EP1 subtype receptor, and antagonizes it. It is less affected by protein binding, so it has a satisfactory in vivo activity. Therefore, it is considered to be useful as an analgesic, an antipyretic agent, an agent for the treatment of pollakiuria (frequent urination) and/or lower urinary tract disease syndrome or an antineoplastic agent.
