Abstract:
A Real-Time Protocol (RTP) source node of a network operates to send a first data packet of a first size to a destination node over a path of the network that includes a plurality of intermediate nodes, at least one of the intermediate nodes having a maximum transmission unit (MTU) size smaller than the first size such that fragmentation of the first data packet occurs. The destination node sends back to the source node a RTCP report that includes a number of fragments received and a largest minimum data packet size. In response, the source node sends subsequent data packets having a second size less than or equal to the largest data packet size of the fragments. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Abstract:
Methods are provided for depositing a dielectric material for use as an anti-reflective coating and sacrificial dielectric material in damascene formation. In one aspect, a process is provided for processing a substrate including depositing an acidic dielectric layer on the substrate by reacting an oxygen-containing organosilicon compound and an acidic compound, depositing a photoresist material on the acidic dielectric layer, and patterning the photoresist layer. The acidic dielectric layer may be used as a sacrificial layer in forming a feature definition by etching a partial feature definition, depositing the acidic dielectric material, etching the remainder of the feature definition, and then removing the acidic dielectric material to form a feature definition.

Abstract:
An interconnect structure is provided that includes a dielectric material (52) having a dielectric constant of 4.0 or less and including a plurality of conductive features (56) embedded therein. The dielectric material (52) has an upper surface that is located beneath an upper surface of each of the plurality of conductive features (56). A first dielectric cap (58) is located on the upper surface of the dielectric material (52) and extends onto at least a portion of the upper surface of each of the plurality of conductive features (56). As shown, the first dielectric cap (58) forms an interface (59) with each of the plurality of conductive features (56) that is opposite to an electrical field that is generated by neighboring conductive features. The inventive structure also includes a second dielectric cap (60) located on an exposed portion of the upper surface of each of the plurality of conductive features (56) not covered with the first dielectric cap (58). The second dielectric cap (60) further covers on an exposed surface of the first dielectric cap (58).
Abstract:
The present invention generally provides apparatus and methods for forming LED structures. One embodiment of the present invention provides a method for fabricating a compound nitride structure comprising forming a first layer comprising a first group-III element and nitrogen on substrates in a first processing chamber by a hydride vapor phase epitaxial (HVPE) process or a metal organic chemical vapor deposition (MOCVD) process, forming a second layer comprising a second group-III element and nitrogen over the first layer in a second processing chamber by a MOCVD process, and forming a third layer comprising a third group-III element and nitrogen over the second layer by a MOCVD process.
Abstract:
A prosthetic mitral valve assembly and method of inserting the same is disclosed. In certain disclosed embodiments, the prosthetic mitral valve assembly includes a stent and valve combination. The stent is designed so that the anchoring portion is positioned above the annulus of the mitral valve and in the left atrium. The stent is radially expandable so that it can expand into position against the walls of the left atrium and accommodate a wide range of anatomies. Contact between the stent and the native tissue in the left atrium reduces paravalvular leakage and prevents migration of the stent once in place.
Abstract:
Methods and apparatus for processing substrates are disclosed herein. The process chamber includes a chamber body, a substrate support pedestal, a pump port and a gas injection funnel. The chamber body has an inner volume and the substrate support pedestal is disposed in the inner volume of the chamber body. The pump port is coupled to the inner volume and is disposed off-center from a central axis of the substrate support pedestal. The pump port provides azimuthally non-uniform pumping proximate to a surface of the substrate support pedestal and creates localized regions of high pressure and low pressure within the inner volume during use. The gas injection funnel is disposed in a ceiling of the chamber body and opposite the substrate support pedestal. The gas injection funnel is offset from the central axis of the substrate support pedestal and is disposed in a region of low pressure.
