摘要:
A method of manufacturing a stamper/imprinter for patterning a recording medium via thermally assisted nano-imprint lithography, comprising steps of: selecting a recording medium for patterning, comprising a substrate with a first coefficient of thermal expasnsion (CTE); providing a first stamper/imprinter comprising a topographically patterned surface having a correspondence to a selected pattern to be formed in a surface of the medium; providing a sheet of a material having a second CTE matching the first CTE; molding a layer of a polymeric material surrounding the sheet of material and having a surface in conformal contact with the topographically patterned surface of the first stamper/imprinter; and separating the layer of polymeric material from the patterned surface of the first stamper/imprinter to form a second stamper/imprinter comprising a topographically patterned stamping/imprinting surface having a correspondence to the selected pattern.

摘要:
A pad structure and passivation scheme which reduces or eliminates IMC cracking in post wire bonded dies during Cu/Low-K BEOL processing. A thick 120 nm barrier layer can be provided between a 1.2 μm aluminum layer and copper. Another possibility is to effectively split up the barrier layer, where the aluminum layer is disposed between the two barrier layers. The barrier layers may be 60 nm while the aluminum layer which is disposed between the barrier layers may be 0.6 μm. Another possibility is provide an extra 0.6 μm aluminum layer on the top barrier layer. Still another possibility is to provide an extra barrier layer on the top-most aluminum layer, such that a top barrier layer of 60 nm is provided on a 0.6 μm aluminum layer, followed by another barrier layer of 60 nm, another aluminum layer of 0.6 μm and another barrier layer of 60 nm.
摘要:
A method of manufacturing a stamper/imprinter for use in patterning of a recording medium comprising the sequential steps of providing a substrate/workpiece comprising a topographical pattern formed in a portion of a surface of the substrate/workpiece. The pattern defines a periphery. An alignment mark is formed in another portion of the surface of surrounding the periphery. An opaque protective film is formed overlying the entirety of the surface. A peripheral portion of the protective film is removed to expose the alignment mark. Selected portions of the substrate/workpiece are removed while the alignment mark is utilized for accurate alignment during the removal process. Remaining portions of the protective film are removed prior to use.

A method of manufacturing a magnetic recording medium comprises steps of providing a non-magnetic substrate having at least one surface; forming a layer of a sol-gel on the surface, partially drying the sol-gel layer at room temperature to remove a portion of the solvent therein to form a partially dried sol-gel layer of hardness less than that of the substrate; mechanically texturing the surface of the partially dried sol-gel layer; and depositing a layer stack including at least one magnetic layer thereover. Embodiments of the invention include embossing a servo pattern in the as-deposited sol-gel layer prior to partial drying and mechanically texturing, followed by sintering at an elevated temperature to form a substantially fully dried layer having a density and hardness similar to that of glass, and formation of a thin film magnetic media layer stack thereon.

A passivation layer comprises a titanium-doped aluminum oxide layer for passivation of ferroelectric materials such as Pt/SBt/Ir—Ta—O devices. The titanium-doped aluminum oxide layer for passivation of ferroelectric materials has reduced stress and improved passivation properties, and is easy to deposit and be oxidized. The passivation layer in the MFM Structure resists breakdown and peeling during annealing of the device in a forming gas ambient.
