20080212238 | Magnetoresistive head with larger longitudinal biasing - Embodiments of the present invention help to efficiently apply a longitudinal biasing with appropriate strength from a longitudinal biasing layer to a free layer even in a small read gap length. According to one embodiment, in the track width direction of the magnetoresistive film, the longitudinal biasing layer excluding its portion close to the magnetoresistive film is made approximately uniform in thickness. An edge toward the magnetoresistive film of the longitudinal biasing layer is positioned more outwardly in the track width direction than an edge in the track width direction of the free layer. A portion closest to the substrate of the interface between the longitudinal biasing layer and the insulator on the track-width sides is positioned lower than the interface between the magnetoresistive film and the lower magnetic shield layer. | 09-04-2008 |
20080218910 | Magnetic detection element and manufacturing method thereof - Embodiments of the present invention help to reduce etching damage at end parts of a magnetoresistive sensor in ion beam etching. According to one embodiment, ion beam etching (IBE) is used in a magnetoresistive sensor track width forming step. This IBE irradiates Ar ion beam to a substrate in a state that the substrate is inclined and further rotates the substrate about its normal as a rotational axis. In a conventional track width forming step, the IBE irradiates the Ar ion beam to the substrate all the time while the IBE is rotating the substrate. By contrast, the IBE according to embodiments of the present invention irradiates the Ar ion beam to the substrate only in a predetermined specific angular range. | 09-11-2008 |
20080239585 | CPP-type magnetoresistive effect head and method of manufacturing the same - Embodiments of the present invention help to prevent a reduction in the bias magnetic field of a current perpendicular to the plane-type (CPP-type) magnetoresistive effect head, thus suppressing a reduction in read output. According to one embodiment, a CPP-type magnetoresistive effect film is formed on top of a lower magnetic shield. A refill insulation film and a magnetic domain control layer are formed on both sides of an intermediate layer and a free layer of the CPP-type magnetoresistive effect film. A side wall protection film is formed on a side wall of the refill insulation film and on top of the free layer so as to define the height of the magnetic domain control layer. To increase the film thickness of the magnetic domain control layer, the magnetic domain control layer and the refill insulation film are higher than the top surface of the free layer. A magnetic shield underlayer film is formed on the top surfaces of the free layer, the magnetic domain control layer and the refill insulation film and an upper magnetic shield layer is formed on the magnetic shield underlayer film. | 10-02-2008 |
20080273274 | Magnetic detection element and manufacturing method thereof - Embodiments of the present invention help to suppress etching damage to a non-magnetic intermediate layer in manufacturing steps of a reproducing head. In one embodiment, a reproducing head has two junction insulating films between side ends of magnetoresistive sensor and hard bias films at both left and right of a track width direction of the magnetoresistive sensor. The reproducing head has first junction insulating films in addition to second junction insulating films. The first junction insulating film suppresses etching damage to the non-magnetic intermediate layer in the manufacturing steps of the reproducing head | 11-06-2008 |
20090004872 | METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE - A semiconductor device is provided which is constituted by semiconductor devices including a thin film transistor with a GOLD structure, the GOLD structure thin film transistor being such that: a semiconductor layer, a gate insulating film, and a gate electrode are formed in lamination from the side closer to a substrate; the gate electrode is constituted of a first-layer gate electrode and a second-layer gate electrode shorter in the size than the first-layer gate electrode; the first-layer gate electrode corresponding to the region exposed from the second-layer gate electrode is formed into a tapered shape so as to be thinner toward the end portion; a first impurity region is formed in the semiconductor layer corresponding to the region with the tapered shape; and a second impurity region having the same conductivity as the first impurity region is formed in the semiconductor layer corresponding to the outside of the first-layer gate electrode, which is characterized in that a dry etching process consisting of one step or two steps is applied to the formation of the gate electrode. | 01-01-2009 |

20090046394 | Sensor shape and etching process of CPP magnetic head for reduce property degradation - Embodiments of the present invention help to prevent a head characteristic from being deteriorated by re-deposition or damage which occurs when a sensor film is etched, a track width is narrowed, and the head characteristic is stabilized. According to one embodiment, when it is assumed that the thickness of the sensor film on an air bearing surface is T, and a distance between an end of a medium layer that is interposed between a free layer and a pinned layer which comprise the sensor film and an end of the sensor film lowest portion, a relationship of 1.2×T≦x≦2.5×T is satisfied, and the ends of a pair of magnetic films which are in contact with both sides in the track-width direction through an insulator do not exist in the track central portion from the free layer end. The sensor film is etched while an incident angle of an etching beam is changed over, and when it is assumed that a direction normal to the sensor film surface is the incident angle of 0, etching is conducted under the condition where the incident angle of the etching beam becomes smaller with time. | 02-19-2009 |
