Abstract: The present invention is directed to non-lithographic patterning by laser (or similar-type energy beam) ablation, where the ablation system ultimately results in circuitry features that are relative free from debris induced over-plating defects (debris relating to the ablation process) and fully additive plating induced over-plating defects. Compositions of the invention include a circuit board precursor having an insulating substrate and a cover layer. The insulating substrate is made from a dielectric material and also a metal oxide activatable filler. The cover layer can be sacrificial or non-sacrificial and is used to remediate unwanted debris arising from the ablation process.

Abstract: A heater for a phase change memory may be formed by depositing a first material into a trench such that the material is thicker on the side wall than on the bottom of the trench. In one embodiment, because the trench side walls are of a different material than the bottom, differential deposition occurs. Then a heater material is deposited thereover. The heater material may react with the first material at the bottom of the trench to make Ohmic contact with an underlying metal layer. As a result, a vertical heater may be formed which is capable of making a small area contact with an overlying chalcogenide material.

Abstract: A system and associated methods are described for preparing a magnetic disk for installation within a disk drive system. For example, a polyfunctional lubricant may be mixed with a chemical agent to esterify the polyfunctional lubricant and cap hydroxyl groups of the polyfunctional lubricant. The magnetic disk may then be dip coated with the polyfunctional lubricant and chemical agent mixture. A polishing system then polishes the magnetic disk via an abrasive polishing tape after dip coating the magnetic disk. A portion of the chemical agent is then removed from the magnetic disk to bond a portion of the lubricant to the magnetic disk to prevent the lubricant from interfering with a read/write head when installed within a disk drive system.

The method includes applying a lubricant onto the protective layer to form the lubricant layer, which includes ejecting shots of a heated lubricant liquid onto the protective layer from a nozzle. The heated lubricant liquid contains a perfluoropolyether lubricant, and each shot is of a quantity in a range of 0.1 to 10 pico liters.

Abstract: A method for making a bit-patterned-media (BPM) magnetic recording disk includes depositing a FePt (or CoPt) alloy recording layer, and then depositing a sealing layer on the FePt layer before high-temperature annealing. The high-temperature annealing causes the FePt to become substantially chemically-ordered in the L10 phase. After annealing, the sealing layer is removed. The sealing layer prevents nanoclustering and agglomeration of the FePt material at the surface of the FePt layer and the sealing layer, which would result in undesirable high surface roughness of the FePt, making patterning of the FePt layer difficult. The FePt layer can be patterned into the discrete islands for the BPM disk either before deposition of the sealing layer or after deposition and removal of the sealing layer. After patterning and removal of the sealing layer, the disk protective overcoat is deposited over the discrete data islands.

Abstract: The invention relates to an apparatus for coating a substrate (60), in particular a printed circuit board (61), with a device (16) for applying a coating material (material applying device) and a device (14) for supplying a gaseous medium (gas supplying device), the material applying device having an inner tubular element (16). The apparatus is distinguished by the fact that the gas supplying device has an outer tubular element (14) which is arranged coaxially in relation to the inner tubular element (16) and encloses the latter, so that a gas supply channel (19) is formed between the outer tubular element (14) and the inner tubular element (16), the supply channel (19) being designed in such a way that the gaseous medium flows out parallel to the coating material, in order to displace the coating material when it impinges on the substrate (60) and in this way distribute it over the surface area. Furthermore, the invention relates to a method for coating a substrate.
