20080213691 | Method to print photoresist lines with negative sidewalls - A write pole for vertical magnetic recording is described. It includes a trapezoidal prism of high magnetic moment material, having inwardly sloping sidewalls. Its parallel surfaces are between about 0.1 and 0.3 microns apart and the sidewalls slope in the range of 15.5 to 60 degrees relative to vertical. | 09-04-2008 |
20110011744 | Novel method to reduce void formation during trapezoidal write pole plating in perpendicular recording - A method of forming a write pole in a PMR head is disclosed that involves forming an opening in a mold forming layer. A conformal Ru seed layer is formed within the opening and on a top surface. An auxiliary layer made of CoFeNi or alloys thereof is formed as a conformal layer on the seed layer. All or part of the auxiliary layer is removed in an electroplating solution by applying a (−) current or voltage during an activation step that is controlled by activation time. Thereafter, a magnetic material is electroplated with a (+) current to fill the opening and preferably has the same CoFeNi composition as the auxiliary layer. The method avoids Ru oxidation that causes poor adhesion to CoFeNi, and elevated surfactant levels that lead to write pole impurities. Voids in the plated material are significantly reduced by forming a seed layer surface with improved wettability. | 01-20-2011 |
20110094888 | Rejuvenation method for ruthenium plating seed - A method of rejuvenating a Ru plating seed layer during write pole fabrication in a PMR head is disclosed that involves forming an opening in a mold forming layer. A Ru seed layer is deposited by CVD within the opening and on a top surface of the mold forming layer. The substrate with the Ru seed layer is immersed in an acidic solution and an electric potential is applied for 1 to 2 minutes such that hydrogen is generated to reduce ruthenium oxides to Ru metal on the seed layer surface in an activation step. One or more surfactants are used to improve wettability of the Ru layer. The substrate is transferred directly to an electroplating solution without drying following the activation step to minimize exposure to oxygen that could regenerate oxides on the surface of the Ru layer. As a result, write pole voids and delamination are significantly reduced. | 04-28-2011 |
20120205344 | Copper plating method - A method of activating a copper seed layer during a plating process is disclosed that comprises application of vapor generated by an ultrasonic wave nebulizer.

The weak organic acid preferably has a pKa high enough to avoid Cu etching but is sufficiently acidic to remove copper oxide at a rate that is compatible with high throughput manufacturing. In one embodiment, weak acid/water vapor is applied to a substrate in a spin bowl and is followed by a deionized water rinse step in the same spin bowl. Improved wettability results in improved uniformity in subsequently plated copper films. Considerable cost savings is realized as a result of reduced chemical consumption and higher product yields. | 08-16-2012 |
20130334051 | Novel Plating Method - An electroplating method is disclosed that selectively deposits a greater thickness of a metal or alloy layer on a region of wafer that has a higher thickness loss during a subsequent chemical mechanical polish process. A paddle assembly has three rectangular sides joined at their edges to form a triangle shape from an end view, and a notch in a bottom side that faces a wafer during the plating process. The notch extends along second and third paddle sides to a height up to about 50% of the paddle thickness. The thickness in a K-block region that has two sides formed parallel to the wafer flat is selectively increased by aligning a first side of the paddle notch side directly over one K-block side and aligning a second notch side directly over a second K-block side during a paddle movement cycle. The notch may be rectangular shaped or tapered. | 12-19-2013 |

20110101891 | VIRTUAL GAP DIELECTRIC WALL ACCELERATOR - A virtual, moving accelerating gap is formed along an insulating tube in a dielectric wall accelerator (DWA) by locally controlling the conductivity of the tube.

The tube conductivity can be controlled at a desired location, which can be moved at a desired rate, by light illumination, or by photoconductive switches, or by other means. As a result, an impressed voltage along the tube appears predominantly over a local region, the virtual gap.
