20120251842 | LOW ROUGHNESS HEATSINK DESIGN FOR HEAT ASSISTED MAGNETIC RECORDING MEDIA - A magnetic recording medium comprises a substrate; a heatsink layer comprising a layer of crystallized CuTi; and a hard magnetic recording layer. The crystallized CuTi is applied in an amorphous state and then crystallized through heating. The use of this heatsink improves surface and underlayer roughness compared to previous heatsink designs. | 10-04-2012 |

20100261352 | METHOD FOR LOW-K DIELECTRIC ETCH WITH REDUCED DAMAGE - A method for etching features in a low-k dielectric layer disposed below an organic mask is provided by an embodiment of the invention. Features are etched into the low-k dielectric layer through the organic mask. A fluorocarbon layer is deposited on the low-k dielectric layer. The fluorocarbon layer is cured. The organic mask is stripped. | 10-14-2010 |

20100108264 | BI-LAYER, TRI-LAYER MASK CD CONTROL - A method for controlling critical dimension (CD) of etch features in an etch layer disposed below a functionalized organic mask layer disposed below an intermediate mask layer, disposed below a patterned photoresist mask, which forms a stack is provided. The intermediate mask layer is opened by selectively etching the intermediate mask layer with respect to the patterned photoresist mask. The functionalized organic mask layer is opened. The functionalized organic mask layer opening comprises flowing an open gas comprising COS, forming a plasma, and stopping the flowing of the open gas. The etch layer is etched. | 05-06-2010 |

20110198240 | Sensors and Methods for Detecting Organic Carbonyl Species - A method for detecting an organic carbonyl species involves exposing a metal oxide-free film of a polyaniline to an environment suspected of containing an organic carbonyl species, detecting a change in electrical conductivity and/or an optical or luminescent property of the polyaniline, and, correlating the change in electrical conductivity and/or optical or luminescent property to a presence of the organic carbonyl species in the environment. Further, sensors for organic carbonyl species are disclosed having a metal oxide-free film of a polyaniline supported on an electrically insulating substrate. The method and sensors provide a good balance between response time and sensitivity, being considerably faster than metal oxide and metal oxide/polymer based sensors, while having greater sensitivity than other polymer-based sensors. | 08-18-2011 |
