摘要： Structures and methods for fabrication servo and data heads of tape modules are provided. The servo head may have two shield layers spaced apart by a plurality of gap layers and a sensor. Similarly, the data head may have two shield layers spaced apart by a plurality of gap layers and a sensor. The distance between the shield layers of the servo head may be greater than the distance between the shield layers of the data head. The material of the gap layers may include tantalum or an alloy of nickel and chromium. The material for the gap layers permits deposition of gap layers with sufficiently small surface roughness to prevent distortion of the tape module and increase the stability of the tape module operation.

摘要： A method for manufacturing a magnetic tape head having a data sensor and a servo sensor. The data sensor and servo sensor are each separated from first and second magnetic shields by a non-magnetic gap layer, and the gap thickness for the servo sensor is larger than the gap thickness for the data sensor. The method involves depositing a first gap layer over shield structures, then depositing a second gap layer using a liftoff process to remove the second gap layer over the data sensor region. A plurality of sensor layers are then deposited, and a stripe height defining mask structure is formed over the data and servo sensor regions, the mask having a back edge that is configured to define a stripe height of the data and servo sensors. An ion milling is then performed to define the stripe height and to remove gap material from the field.

The read head includes a magnetoresistive sensor with first and second magnetic, electrically conductive shields separated from a substrate by a layer of non-magnetic, electrically insulating material. A dummy magnetic shield is formed on the non-magnetic electrically insulating layer and is electrically connected with the second magnetic, electrically conductive shield. The dummy shield is formed to have a capacitive coupling with the substrate that matches the capacitive coupling of the first magnetic, electrically conductive shield with the substrate.

摘要： A method for detecting defects in devices that are fabricated in repetitive patterns upon the surface of a substrate by the, repetitive utilization of masks and similar devices. A mask flaw will become manifest in a series of defective devices as the mask is successively utilized. The detection of repetitive defects is undertaken by determining the electrical resistance of devices in a group, such as a column, fabricated upon the wafer surface, where the repetitive defect will occur multiple times. The mean electrical resistance of the group is determined and a percent deviation of each device from the mean is then determined. The percent deviation of all of the devices in the group are multiplied together to create a multiplied percent deviation number and the multiplied percent deviation number is then compared with a figure of merit value to make a determination of whether defective devices exist within the group.
