20130032887 | SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREOF - A manufacturing method for manufacturing a semiconductor device includes depositing a spacer material on a semiconductor substrate, the substrate includes an NMOS region and a PMOS region, each region has a gate formed thereon. The method further includes covering the NMOS region with a first mask, forming a spacer for the PMOS gate by etching the spacer material, forming a recess in the PMOS region by etching, and growing SiGe or SiGe with in-situ-doped B in the recess of the PMOS region to form a PMOS source/drain region. The method further includes performing an anisotropic wet etching on the recess. After growing SiGE or SiGe with in-situ-doped B, the method further includes covering the PMOS region with a second mask and forming a spacer for the NMOS gate by etching the spacer material. The spacer for the PMOS and NMOS gate has a different critical dimension. | 02-07-2013 |

20110207880 | PEROXIDIC FLUOROPOLYETHER AND ITS USE IN EMULSION POLYMERIZATION OF FLUORIN-CONTAINING MONOMER - The present invention provides peroxidic fluoropolyether and a fluorin-containing dispersion obtained from polymerization of fluorin-containing monomers in the presence of peroxidic fluoropolyether as a surfactant. The peroxidic fluoropolyether can be used as surfactant for producing aqueous dispersion of fluorin-containing monomer in place of PFOA or the salts thereof. Thus the amount of PFOA or the salts thereof is reduced and the natural environment is protected. In addition, applying peroxidic fluoropolyether as surfactant and combining it with adjuvants, such as initiator, can induce the reaction moderate and can be beneficial to the polymerization control, thus reducing the amount of initiator or shortening the reaction time. | 08-25-2011 |
