Patent number: 9382566Abstract: Open chain sophorolipids may be produced by fermentation with Candida sp. NRRL Y-27208 or C. riodocensis. Dimers and trimers of sophorolipids are also produced. The sophorolipds are produced by inoculating a fermentation medium comprising a carbon source and a lipid, with Candida riodocensis or Candida species NRRL Y-27208, and incubating under aerobic conditions and for a period of time effective to produce an open chain sophorolipid in the medium. The sophorolipids may be subsequently recovered from the fermentation medium.Type: GrantFiled: September 30, 2013Date of Patent: July 5, 2016Assignee: The United States of America, as represented by the Secretary of AgricultureInventors: Cletus P. Kurtzman, Neil P. Price, Karen J. Ray, Tsung Min Kuo

Patent number: 8975673Abstract: A method of trimming spacers includes etching a silicon oxide spacer when forming an outmost spacer, so that a silicon carbon nitride spacer contacting the gate electrode exposes an area. The exposure area of the silicon carbon nitride spacer can then be partly removed by phosphate acid. At the end of the semiconductor process, at least part of the top surface of the silicon carbon nitride spacer will be lower than the top surface of a gate electrode.Type: GrantFiled: April 16, 2012Date of Patent: March 10, 2015Assignee: United Microelectronics Corp.Inventors: Shyan-Liang Chou, Tsung-Min Kuo, Po-Wen Su, Chun-Mao Chiou, Feng-Mou Chen
