摘要： Multiple-layer thin film devices are deposited by electroplating on an otherwise substantially clean substrate wafer. The composition of the electroplated alloy layers is maintained substantially uniform using a cathode assembly on which the substrate wafer is mounted. The cathode assembly includes an inner cathode ring electrically connected to the wafer, a thief ring external to the cathode ring and an insulating ring connected between and electrically insulating the cathode and thief rings. The cathode ring and the thief ring are powered by separate power sources.

摘要： An electroless plating apparatus heats a plating bath solution with precise uniformity and avoids localized high temperatures within the bath. The electroless plating apparatus achieves this performance using two solution tanks included an inner tank nested inside an outer tank. A distributed heating element encases a plurality of surfaces of the outer tank, which contains an ethylene glycol solution. The inner tank contains a plating bath solution. A substrate is placed inside the inner tank for plating. Each of the outer tank and the inner tank include a device for evenly distributing the applied heat. In one embodiment, the outer tank heat distributing device is a pump which mixes the ethylene glycol solution. The inner tank heat distributing device is a pump which recirculates plating bath solution, applying returning solution via a sparger.

摘要： A thin film magnetic head is fabricated on a substrate by depositing a seed layer on the substrate. This seed layer is advantageously used as a common seed for a plurality of magnetic head related structures which are built-up on the substrate. A lower magnetic layer is plated on the substrate in an opening provided in an insulative layer which is deposited on the substrate. The aforementioned seed layer is used as the seed for this lower magnetic layer. A plurality of magnetic layers are plated at one end of the lower magnetic layer to build-up and form a first side pole by using the above seed layer as a seed. Another plurality of magnetic layers are plated at the other end of the lower magnetic layer to build-up and form a second side pole by using the same seed layer as a seed. The first and second side poles thus formed include upper and lower ends, the lower ends being plated to the ends of the lower magnetic layer. A first upper pole is plated to the upper end of the first side pole. The first upper pole includes a gap end facing the second side pole. A gap region of nonmagnetic material is deposited adjacent the gap end of the first upper pole. A second upper pole is plated to the upper end of the second side pole and includes a gap end adjacent the gap region.

摘要： A method for fabricating a transducer on a substrate is described. The transducer includes an antiferromagnetic seed structure. The antiferromagnetic seed structure includes a first NiFe layer, a first multilayer including a first Ru layer, a second NiFe layer, and a second multilayer including a second Ru layer. The second multilayer, the second NiFe layer and part of the first Ru layer are removed using a first wet etch, which uses a first etchant combination to remove NiFe and in which Ru is insoluble. The second Ru layer is removed through lift-off due to etching of the second NiFe layer. A remainder of the first Ru layer is removed through a second wet etch, which uses a second etchant combination to remove Ru. A remaining portion of the first multilayer and the first NiFe layer are removed through a third etch, which uses a third etchant combination that removes NiFe.

摘要： A thin film magnetic head is fabricated on a substrate by depositing a lower shield layer on the substrate. A lower layer of a magnetic yoke is situated on the lower shield layer to couple the yoke to the shield. Alternatively, the magnetic yoke is isolated from the lower shield layer by an insulative layer therebetween. At the same time that first and second magnetic side poles are built up layer by layer via successive plating operations at the respective ends of a lower magnetic layer of the yoke, a side shield structure is plated up, layer by layer, at the periphery of the lower shield layer to surround resultant side pole structure. A shield cover is plated on the top of the side shield to substantially enclose the side pole structure, but leave an opening for an insulative pedestal though which the tops of the side poles extend. First and second magnetic poles are plated to the tops of the first and second side poles such that a gap region of non-magnetic material is formed therebetween.
