20120161264 | JUNCTION ISOLATION FOR MAGNETIC READ SENSOR - Embodiments generally relate to a magnetic read sensor and a method for its manufacture. A multi-layer insulating material may be used to cover both the first shield layer and also the sidewalls of the sensor structure in the magnetic read sensor. The first insulating layer of the multi-layer insulating material may be deposited by an ion beam sputtering process in a chamber that does not have any oxygen gas flowing into it so that oxygen diffusion into the sensor structure is reduced or eliminated. Then, a second insulating layer of the multi-layer insulating material may be deposited by atomic layer deposition such that the second insulating layer has a greater quality than the first insulating layer. The higher quality increases the breakdown voltage for the magnetic read sensor. Thus, the magnetic read sensor of the present invention has an effective insulating portion that increases the breakdown voltage without sensor damage. | 06-28-2012 |
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 |

20130114334 | Magnetoresistive random access memory cell with independently operating read and write components - A new class of the memory cell is proposed. There are two separated pulse data writing and sensing current paths. The in-plane pulse current is used to flip the magnetization direction of the perpendicular-anisotropy data storage layer sandwiched between a heavy metal writing current-carrying layer and a dielectric layer. The magnetization state within data storage layer is detected by the patterned perpendicular-anisotropy tunneling magnetoresistive (TMR) stack via the output potential of the stack. Two detailed memory cells are proposed: in one proposed cell, the data storage layer is independent from but kept close to the sensing TMR stack, whose magnetization orientation affects magnetization configuration within the free layer of the TMR stack, therefor ultimately affects the output potential of the stack; in the other proposed cell, the perpendicular-anisotropy data storage layer is the free layer of the sensing TMR stack, whose magnetization state will directly affect the output potential of the stack when sensing current passes through. | 05-09-2013 |

The scheme implements pairing patterned magnets predetermined designed and made using wafer level process on two components (wafer or chip). The magnetization in patterned magnet can be set at predetermined configuration before bonding starts.
