    摘要: Techniques for removal of photolithographic films used in the manufacture of semiconductor devices are provided. A substrate support member of a first processing chamber includes at least three retractable pins capable of elevating a wafer from a surface of the substrate support member. In addition, the first processing chamber is configured to automatically maintain the substrate support member at a first temperature. The wafer is elevated from the surface of the substrate support member using the at least three retractable pins. Thermal heating of the substrate from the substrate support member is reduced. A photoresist layer of the substrate is etched away while the substrate is in an elevated position. An anti-reflective layer of the substrate can be etched to remove substantially all of the anti-reflective layer. In a specific embodiment, the anti-reflective layer includes a DUO™ Bottom Anti-Reflective Coating by Honeywell International Inc.

    摘要: A system and method to perform discretization and cardinality reduction of item attributes using collaborative filtering techniques are described. Data input by a user is received over a network, the input data further including a plurality of items and associated item metadata related to events performed by the user. The input data is further processed to obtain a predetermined number of groupings, each grouping having a calculated value based on a distance parameter between corresponding attributes of each item stored within the item metadata. Finally, a similarity parameter is computed between each pair of items within the plurality of items based on associated groupings and recommendations of the items are presented to the user based on the corresponding calculated similarity parameter.

    摘要: A reliquifier using a cryocooler in which an insulated sleeve surrounds a portion of the cold head, a first stage cooling station, and a second stage cooling station, including a condenser. Gas is conveyed from a cryostat to the insulated sleeve, where it is liquefied as it passes over the cold head. An end of the insulated sleeve is connected to a liquid transfer tube for conveying condensed fluid back to the cryostat.

    摘要: A differential space-time block coder produces successive space-time blocks of symbols from M-PSK symbols to be encoded, in accordance with an orthogonal matrix and a normalization factor. Differentially encoded space-time output blocks, for transmission via a plurality of transmit antennas (16, 18) of a wireless communications system, are produced by multiplying (42) each space-time block from the space-time block coder (40) by the respective previous (44) differentially encoded space-time output block. Decoding is independent of channel estimation, and the arrangement is simple, avoids error propagation, and is applicable to different numbers of transmit antennas.

    摘要: An additive manufacturing process for forming a metallic layer on the surface of the substrate includes fabricating a substrate from a polymerizable composition by a stereolithographic process, and contacting the reactive surface with an aqueous solution including a metal precursor. The metal precursor includes a metal, and the polymerizable composition includes a multiplicity of multifunctional components. Each multifunctional component includes a reactive moiety extending from a surface of the substrate to form a reactive surface. An interface between the reactive surface and the aqueous solution is selectively irradiated to form nanoparticles including the metal in a desired pattern. The nanoparticles are chemically coupled to the reactive surface by reactive moieties, thereby forming a metallic layer on the surface of the substrate.

    摘要: A method and device for feeding back downlink channel feedback information, and a method and device for user pairing. The method for feeding back downlink channel feedback information includes: calculating the multi-user channel quality indication error of a user, which error is used to reflect the difference in channel quality indication between the situation of multi-user multiple input multiple output transmission and the situation of single user multiple input multiple output transmission; adding the multi-user channel quality indication error into the downlink channel feedback information which includes a pre-coding matrix indication and a channel quality indication, and feeding the same back to a base station for scheduling. Therefore, the bit error rate of demodulation in the MIMO system can be reduced and the system performance can be improved.

    摘要: The present embodiments provide a gradient coil assembly. The gradient coil assembly includes an aluminum wire body, and a copper wire end connected by cold pressure welding to two ends of the aluminum wire body. Using the gradient coil according to a particular embodiment, it is possible to reduce gradient coil weight as well as reduce the thickness of an outer vacuum chamber used for a magnet, thereby reducing the cost of the magnet and gradient coil, and making it less difficult to install and maintain the magnet and gradient coil. There is no problem of oxidation associated with the cold pressure welding of the aluminum wire body to the copper wire ends, so quality defects arising from such oxidation are avoided.
