20120080725 | VERTICAL TRANSISTOR MEMORY ARRAY - A method includes providing a semiconductor wafer having a plurality of pillar structures extending orthogonally from the semiconductor wafer. An electrically conducting interconnect element is deposited onto at least selected vertical pillar transistors and a non-volatile variable resistive memory cell is deposited onto the electrically conducting interconnect layer to form a vertical transistor memory array. | 04-05-2012 |
20120231296 | METHOD FOR MANUFACTURING AN ADVANCED MAGNETIC READ SENSOR - A method for manufacturing a magnetic sensor that minimizes topography resulting from stripe height defining masking and patterning in order to facilitate definition of track width. The method includes depositing a series of mask layers and then masking and ion milling the series of sensor layers to define a back edge of a sensor. A non-magnetic fill layer is then deposited, the magnetic fill layer being constructed of a material that has an ion mill rate that is similar to that of the series of sensor layers. A second masking and milling process is then performed to define the track width of the sensor and hard bias is deposited. Because the non-magnetic fill layer is removed at substantially the same rate as the sensor material the structure has a very flat topography on which to form the sensor track width. | 09-13-2012 |
20130082696 | MAGNETIC BIAS STRUCTURE FOR MAGNETORESISTIVE SENSOR HAVING A SCISSOR STRUCTURE - A scissor style magnetic sensor having a novel hard bias structure for improved magnetic biasing robustness. The sensor includes a sensor stack that includes first and second magnetic layers separated by a non-magnetic layer such as an electrically insulating barrier layer or an electrically conductive spacer layer. The first and second magnetic layers have magnetizations that are antiparallel coupled, but that are canted in a direction that is neither parallel with nor perpendicular to the air bearing surface by a magnetic bias stricture. The magnetic bias structure includes a neck portion extending from the back edge of the sensor stack and having first and second sides that are aligned with first and second sides of the sensor stack. The bias structure also includes a tapered or wedged portion extending backward from the neck portion. | 04-04-2013 |
20130083432 | MAGNETIC BIAS STRUCTURE FOR MAGNETORESISTIVE SENSOR - A magnetic read head having a hard bias structure that both optimizes magnetic bias field and also ensures manufacturability while maintaining sensor stripe height integrity. The read head includes a sensor stack having a back edge and first and second laterally opposed sides. A hard bias structure extending from each of the first and second sides of the sensor stack has a neck portion located near the sensor and having a back edge that is aligned with and parallel to the back edge of the sensor stack. The hard bias structure also includes a flared portion having a back edge that defines an angle relative to the air bearing surface of the read head. The back edge preferably defines and angle of 45-75 degrees relative to the air bearing surface. | 04-04-2013 |
20130135772 | METHOD FOR MANUFACTURING A MAGNETIC SENSOR USING TWO STEP ION MILLING - A method for manufacturing a magnetic sensor that includes depositing a plurality of mask layers, then forming a stripe height defining mask over the sensor layers. A first ion milling is performed just sufficiently to remove portions of the free layer that are not protected by the stripe height defining mask, the first ion milling being terminated at the non-magnetic barrier or spacer layer. A dielectric layer is then deposited, preferably by ion beam deposition. A second ion milling is then performed to remove portions of the pinned layer structure that are not protected by the mask, the free layer being protected during the second ion milling by the dielectric layer. | 05-30-2013 |
20130163121 | MAGNETIC SENSOR HAVING HARD BIAS STRUCTURE FOR OPTIMIZED HARD BIAS FIELD AND HARD BIAS COERCIVITY - A magnetic read sensor having a hard bias structure that extends beyond the back edge of the sensor stack by a controlled, distance that is chosen to maximize both hard bias field and hard bias magnetic coercivity and anisotropy. The hard bias structure has a back edge that is well defined and that has a square corner at its innermost end adjacent to the sensor stack. The magnetic sensor can be constructed by a process that includes a separate making an milling process that is dedicated to defining the back edge of the hard bias structure. | 06-27-2013 |
20140175576 | SHAPE ENHANCED PIN READ HEAD MAGNETIC TRANSDUCER WITH STRIPE HEIGHT DEFINED FIRST AND METHOD OF MAKING SAME - The present invention generally relates to a magnetic sensor in a read head having a hard or soft bias layer that is uniform in thickness within the sensor stack. The method of making such sensor is also disclosed. The free layer stripe height is first defined, followed by defining the track width, and lastly the pinned layer stripe height is defined. The pinned layer and the hard or soft bias layer are defined in the same process step. This approach eliminates a partial hard or soft bias layer and reduces potential instability issues. | 06-26-2014 |
20150118520 | LOW RESISTANCE MAGNETIC SENSOR WITH EXTENDED PINNED LAYER STRUCTURE - A magnetic read sensor having improved pinning and reduced area resistance. The sensor has pinned magnetic layer that extends beyond the functional stripe of the sensor to improve magnetic pinning. The free layer has a magnetic portion that extends to the functional stripe height and a non-magnetic portion that extends beyond the functional stripe height. The sensor may have an end point detection layer located between the magnetic pinned layer and the magnetic free layer. | 04-30-2015 |
