摘要: A process for fabricating a magnetic recording transducer for use in a data storage system comprises providing a substrate, an underlayer and a first nonmagnetic intermediate layer deposited to a first thickness on and in contact with the underlayer, performing a first scanning polishing on a first section of the first intermediate layer to planarize the first section of the first intermediate layer to a second thickness, providing a main pole in the planarized first section of the first intermediate layer, providing a first pattern of photoresist on and in contact with the first section of the first intermediate layer, the pattern comprising an aperture to define a side shield trench, performing a wet etch to remove at least a portion of the first intermediate layer thereby exposing at least one of the plurality of main pole sides, and depositing side shield material in the side shield trench.
