    摘要： A method for use in making a magnetic write head includes the steps of forming a first pole piece layer of a first pole piece; forming a patterned resist over the first pole piece layer; electroplating a pedestal over the first pole piece layer within a channel of the patterned resist; electroplating a metal gap layer over the pedestal within the channel of the patterned resist; forming a resist channel shrinking film over the patterned resist; baking the resist channel shrinking film over the patterned to thereby reduce a width of the channel; removing the resist channel shrinking film; electroplating a second pole piece within the reduced-width channel of the patterned resist; removing the patterned resist; and milling the pedestal, using the second pole piece as a mask, to form a central notched pedestal having side walls with angled slopes. Advantageously, the reduction in channel width using the resist channel shrinking film provides for self-alignment of the second pole piece with the pedestal which can be symmetrically notched for improved overwrite (OW) properties and reduced adjacent track interference (ATI).

The suspended particles include a sublimation dye and have a melting point of at least a surface of the particle greater than or equal to 200° C.

    摘要： A method is presented for repairing damaged photomasks for electronic component fabrication processes, particularly for fabrication of the ABS of a disk drive slider. The method includes applying an overcoat of material having index of fraction which is close to the index of refraction of the photoresist material of the damaged photomask to produce a non-scattering boundary surface. The overcoat material preferably includes an overcoat base material which is a polymer having an index of refraction which is in the range of plus or minus 0.1 from the index of refraction of said photoresist material.

    摘要： The present invention provides phosphor inks configured to achieve high efficiency in converting LED light from one wavelength to another. The phosphor ink composition for deposition on an LED device comprises a phosphor component having nano-phosphor particles on the order of 100 to 1000 nanometers, and a curable resin component. In particular, the nano-phosphor particles are uniformly dispersed throughout the ink composition. The nano-phosphor particles may be formed by a size reduction process carried out on larger phosphor particles on the order of 1 to 50 micrometers. Preferably, the size reduction process is based on solvent wet milling. Methods for preparing the phosphor inks based on forming the nano-phosphor particles from larger particles by solvent wet milling are also provided.

    摘要： The present invention provides an ink jet printable phosphor ink composition for LED packaging that enables precision control of the amount and position of phosphor layers on the LED device or the LED device packaging. The ink includes both a UV-curable resin component and a thermally curable resin component. A phase-separation component prevents phase separation of the UV-curable resin component and the thermally curable resin component. Phosphor particles on the order of less than approximately 2 microns are uniformly dispersed throughout the ink composition. The phosphor ink composition is deposited through either thermal or piezoelectric ink jet printing; a thin layer is deposited in a desired pattern. UV curing (and, optionally, thermal curing) is used to fix each layer followed by subsequent deposition and curing. In this manner, undesirable phosphor settling does not occur and layers are selectively built up to form precise phosphor distributions.

    摘要： A system and method for patterning a master disk or “stamper” to be used for nanoimprinting magnetic recording disks uses an air-bearing slider that supports an aperture structure within the optical near-field of a resist layer on a rotating master disk substrate. Laser pulses directed to the input side of the aperture are output to the resist layer. The aperture structure includes a metal film reflective to the laser radiation with the aperture formed in it. The aperture has a size less than the wavelength of the incident laser radiation and is maintained by the air-bearing slider near the resist layer to within the radiation wavelength. The timing of the laser pulses is controlled to form a pattern of exposed regions in the resist layer, with this pattern ultimately resulting in the desired pattern of data islands and nondata islands in the magnetic recording disks when they are nanoimprinted by the master disk.
