    摘要: An extraordinary magnetoresistance (EMR) sensor has a planar shunt and planar leads formed on top of the sensor and extending downward into the semiconductor active region, resulting. Electrically conductive material, such as Au or AuGe, is first deposited into lithographically defined windows on top of the sensor. After liftoff of the photoresist a rapid thermal annealing process causes the conductive material to diffuse downward into the semiconductor material and make electrical contact with the active region. The outline of the sensor is defined by reactive etching or other suitable etching techniques. Insulating backfilling material such as Al-oxide is deposited to protect the EMR sensor and the edges of the active region. Chemical mechanical polishing of the structure results in a planar sensor that does not have exposed active region edges.

    摘要: A slider for magnetic data recording having a semiconductor based magnetoresistive sensor such as a Lorentz magnetoresistive sensor formed on an air bearing surface of the slider body. The slider is constructed of Si, which advantageously provides a needed physical robustness as well being compatible with the construction of a semiconductor based sensor thereon. A series of transition layers are provided between the surface of the Si slider body and the semiconductor based magnetoresistive sensor in order to provide a necessary grain structure for proper functioning of the sensor. The series of transition layers can be constructed of layers of SiGe each having a unique concentration of Ge.

    摘要: A structure for preventing Electrostatic Discharge (LSD) damage to a magnetoresistive sensor during manufacture. The structure includes a switching element that can be switched off during testing of the sensor and then switched back on to provide ESD shunting to the sensor. The switch can be a thermally activated mechanical relay built onto the slider. The switch could also be a programmable resistor that includes to solid electrolyte sandwiched between first and second electrodes. One of the electrodes functions as an anode. When voltage is applied in a first direction an ion bridge forms across through the electrolyte across electrodes making the resistor conductive. When a voltage is applied in a second direction, the ion bridge recedes and the programmable resistor becomes essentially non-conductive.

    摘要: EMR elements and methods of fabricating the EMR elements are disclosed. The EMR structure includes one or more layers that form an active region, such as a two-dimensional electron gas (2DEG). The EMR structure has a first side surface, having a plurality of lead protrusions that extend outwardly from the main body of the EMR structure, and an opposing second side surface. The lead protrusions are used to form the current and voltage leads for the EMR element. The active region extends through each lead protrusion and is accessible along a perimeter of each of the lead protrusions. Conductive material is formed along the perimeter of each lead protrusion and contacts the active region of the EMR structure along the perimeter. The lead protrusion and the corresponding conductive material contacting the active region of each lead protrusion form leads for the EMR element, such as current leads and voltage leads.
