摘要:
A method of treating a copper containing structure on a substrate is disclosed. The method includes electrodepositing the copper containing structure on a substrate, annealing the copper containing structure, and forming an interface between a pad of the copper containing structure and a solder structure after anneal. The interface can have improved resistance to interfacial voiding. The copper containing structure is configured to deliver current between one or more ports and one or more solder structures in the integrated circuit package. Annealing the copper containing structure can move impurities and vacancies to the surface of the copper containing structure for subsequent removal.

Disclosed herein are methods of cleaning a lipseal and/or cup bottom of an electroplating device by removing metal deposits accumulated in prior electroplating operations. The methods may include orienting a nozzle such that it is pointed substantially at the inner circular edge of the lipseal and/or cup bottom, and dispensing a stream of cleaning solution from the nozzle such that the stream contacts the inner circular edge of the lipseal and/or cup bottom while they are being rotated, removing metal deposits. In some embodiments, the stream has a velocity component against the rotational direction of the lipseal and/or cup bottom. In some embodiments, the deposits may include a tin/silver alloy. Also disclosed herein are cleaning apparatuses for mounting in electroplating devices and for removing electroplated metal deposits from their lipseals and/or cup bottoms. In some embodiments, the cleaning apparatuses may include a jet nozzle.
摘要:
Methods, systems, structures and arrays are disclosed, such as a resistive memory array which includes access devices, for example, back-to-back Zener diodes, that only allow current to pass through a coupled resistive memory cell when a voltage drop applied to the access device is greater than a critical voltage. The array may be biased to reduce standby currents and improve delay times between programming and read operations.

Described are film(s) and/or sheet(s) made using polyester compositions comprising polyesters containing (a) a dicarboxylic acid component having from about 70 to 100 mole % of terephthalic acid residues, and up to about 30 mole % of aromatic dicarboxylic acid or aliphatic dicarboxylic acid residues; and (b) a glycol component comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and 1,4-cyclohexanedimethanol.
摘要:
In a method and magnetic resonance apparatus for acquisition of image data for a magnetic resonance image, the image data are acquired with an acquisition sequence, in which a k-space matrix corresponding to the image data is scanned in segments with at least two partial acquisitions and in which each of the partial acquisition includes a navigator signal in addition to the measurement signal with which a specific k-space segment is scanned, with which navigator signal a same navigator segment of the k-space matrix is scanned. In one of the partial acquisitions a measure is determined that characterizes the breadth of the distribution of signal values of the navigator signal with regard to the k-space matrix and the partial acquisition is repeated if and when the measure lies outside of a tolerance range.
摘要:
In the operation of a magnetic resonance system, an RF excitation coil emits an excitation pulse such that nuclei in an examination subject are excited to emit of magnetic resonance signals. A number of local coils acquire the magnetic resonance signals emitted from the examination subject, with the magnetic resonance signals acquired by the local coils being coded in frequency space. An evaluation device accepts the magnetic resonance signals acquired by the local coils or accepts intermediate signals derived therefrom via one transmission channel per signal, and corrects the accepted signals using correction signals. The evaluation device uses the corrected signals reconstructing an image of the examination subject. The evaluation device determines the correction signals for all signals to be corrected using the same reference signal.
摘要:
Uracil reductase inactivators, notably a 5-substituted uracil or 5,6-dihydro-5-substituted uracil, potentiate 5-flourouracil and find use particularly in the treatment of cancer. The 5-substituent is selected from bromo, ido, cyano, halo-substituted C1-4 alkyl C2-6 alkenyl, 1-halo-C2-6 alkenyl and halo-substituted C2-6 alkynyl.
摘要:
Described are polyester compositions comprising at least one polyester which comprises terephthalic acid residues, 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and 1,4-cyclohexanedimethanol, wherein the inherent viscosity and the Tg of the polyester provides for certain polyester properties. The polyesters may be manufactured into articles such as fibers, films, bottles or sheets.
