摘要： A method for nano-patterning includes imprinting features in a resist with an imprint mold to form one or more topographic surface patterns on the imprinted resist. A a block copolymer (“BCP”) material is deposited on the imprinted resist, wherein a molecular dimension L0 of the BCP material correlates by an integer multiple to a spacing dimension of the one or more topographic surface patterns on the imprinted resist. The deposited BCP is annealed and at least a portion of the annealed BCP is removed, forming a template having discrete domains.

摘要： One preferred method for use in making a magnetic write head with use of the resist channel shrinking solution includes the steps of forming a first pole piece layer of a first pole piece; forming a gap layer over the first pole piece layer; forming a patterned resist over the first pole piece layer and the gap layer; electroplating a first pedestal portion of a second pole piece over the gap layer within a channel of the patterned resist; forming an oxide layer over the first pedestal portion; applying the resist channel shrinking solution comprising the resist channel shrinking film and the corrosion inhibitors over the patterned resist; baking the resist channel shrinking solution over the patterned resist to thereby reduce a width of the channel; removing the resist channel shrinking solution; electroplating a second pedestal portion of the second pole piece within the reduced-width channel of the patterned resist; removing the patterned resist; and milling the structure. Advantageously, the oxide layer and the corrosion inhibitors of the resist channel shrinking solution reduce corrosion in the pole piece during the act of baking the resist channel shrinking solution.

A subtractive process is disclosed wherein a portion of a magnetic material layer is removed from the substrate using conventional lithography, and the remaining portion of the magnetic material layer is patterned by e-beam lithography. A additive process is also disclosed wherein a thin magnetic seed layer is deposited on the substrate, a portion of which is removed by conventional lithography and replaced with a non-magnetic conducting layer. The remaining portion of magnetic seed layer is patterned by e-beam lithography and the final magnetic structure produced by electroplating.

摘要： A circuit and a method are presented which allow for the detection of an active communication device connected to the circuit. The circuit output signal can be used to reduce the power consumption of related equipment when communication is not detected for a predetermined period of time. The circuit includes a plurality of input terminals coupled to respective inactive detection blocks. The circuit also includes an accumulated delay block having delay circuits in serial electrical communication. Each inactive detection block provides a signal to a respective delay circuit that indicates whether the corresponding input terminal is connected to an active driver in the communication device. Each delay circuit provides a delayed output signal to a subsequent delay circuit. The accumulated delay block provides an output signal indicating the presence or absence of the communication device based on the activity at the input terminals over the predetermined period of time.

摘要： The present invention provides an apparatus and method for producing entangled photon pairs via four-wave mixing in optical fiber. The source of entangled photons is designed to be stable with no manual alignment. This is accomplished with proper system design using polarization maintaining fibers or polarization controllers with feedback control. The source may contain a method of switching the output from an unpolarized entangled state to a polarized state, where the polarized state can be used to more easily align subsequent photon measurement systems to the proper configuration for measuring the unpolarized entangled state. The invention further provides a means to engineer the apparatus, including the use of a periodic filter common to both entangled pairs, such that the wavelength spacing between the pairs can be optimized such that multiple pairs can be generated with reduced adverse influence from Raman scattering.
