| 20090200564 | Method and Structure for Fabricating Smooth Mirrors for Liquid Crystal on Silicon Devices - A method for fabricating a liquid crystal on silicon display device. The method includes providing a substrate, e.g., silicon wafer. The method includes forming a transistor layer overlying the substrate. Preferably, the transistor layer has a plurality of MOS devices therein. The method includes forming an interlayer dielectric layer (e.g., BPSG, FSG) overlying the transistor layer. The method includes planarizing the interlayer dielectric layer and forming a sacrificial layer (e.g., bottom antireflective coating, polymide, photoresist, polysilicon) overlying the planarized interlayer dielectric layer. The method includes forming a plurality of recessed regions within a portion of the interlayer dielectric layer through the sacrificial layer while other portions of the interlayer dielectric layer remain intact. Preferably, lithographic techniques are used for forming the recessed regions. The method includes forming an aluminum layer (or other reflective layer or multilayers) to fill the recessed regions and overlying remaining portions of the sacrificial layer and selectively removing the aluminum layer overlying portions of the sacrificial layer to form a plurality of electrode regions corresponding to each of the recessed regions. | 08-13-2009 |

| 20080274609 | Method and structure for low-K interlayer dielectric layer - An integrated circuit interconnect structure. The structure includes a substrate and a layer of transistor elements overlying the substrate. A first interlayer dielectric layer is formed overlying the layer of transistor elements. An etch stop layer is formed overlying the first interlayer dielectric layer. A contact structure including metallization is within the first interlayer dielectric layer and a metal layer is coupled to the contact structure. A passivation layer is formed overlying the metal layer. Preferably, an air gap layer is coupled between the passivation layer and the metal layer, the air gap layer allowing a portion of the metal layer to be free standing. Depending upon the embodiment, a portion of the air gap layer may be filled with silicon bearing nanoparticles, which may be oxidized at low temperatures. This oxidized layer provides mechanical support and low k dielectric characteristics. Preferably, a portion of the air gap layer is filled with a low k dielectric material as well. | 11-06-2008 |

| 20090323536 | METHOD, DEVICE AND SYSTEM FOR NETWORK INTERCEPTION - A method, a device, and a system for network interception are provided. The method for network interception includes the following steps. A matching rule obtained by parsing an interception policy. Received data are selected by adopting a deep packet inspection (DPI) according to the matching rule so as to obtain an interception result, in which the received data are obtained by adopting data preprocessing to filter packet data according to a service customizing rule obtained by parsing the interception policy. The system for network interception includes a service probe server (SPS) and a service analyze server (SAS). Thus, various packet data services transmitted over an Internet protocol (IP) network can be intercepted. | 12-31-2009 |
