    摘要: A method for manufacturing a write pole for a perpendicular magnetic write head. The method employs a damascene process to construct the write pole with a very accurately controlled track width. The method includes depositing a layer of material that can be readily removed by reactive ion etching. This material can be referred to as a RIEable material. A mask is formed over the RIEable material and a reactive ion etching is performed to form a tapered trench in the RIEAble material. A CMP stop layer can the be deposited, and a write pole plated into the trench. A CMP can then be performed to define the trailing edge of the write pole. Another masking, etching and plating step can be performed to form a trailing, wrap-around magnetic shield.

    摘要: A method for manufacturing a magnetic write head having a wrap around magnetic shield. The method allows a highly accurate short wavelength such as 193 mm photolithography to be used to accurately define the placement and critical dimension of wrap around magnetic shield. The method includes the formation of a magnetic write pole, top gap, and side gap and the deposition of a RIEable fill layer thereover, and CMP to planarization. A 193 nm photolithography and ion milling is used to form a mask over the RIEable layer and one or more reactive ion etching processes are performed to pattern the RIEable layer through 193 nm photolithography mask. A wrap around shield can then be electroplated into the opening formed in the RIEable layer.

    摘要: Methods of fabricating perpendicular write elements for perpendicular magnetic recording heads are discussed. In write element fabrication, write poles are fabricated according to one of many desired methods. The write poles during fabrication are typically covered by a hard mask and a photolithographic soft mask. According to the methods described herein, the soft mask is removed such as by chemical etching. The hard mask is then removed, such as by CMP and ion etching, to expose the write poles. Shield gap material may then be deposited on the write poles to define the shield gap between the write poles and the trailing shields. Trailing shield material may then be deposited on the shield gap material to form the trailing shields corresponding with the write poles.
