METHOD FOR MANUFACTURING A MAGNETIC WRITE HEAD WITH A FLOATING LEADING SHIELD
摘要:
A method for manufacturing a magnetic write head having a write pole with a tapered leading edge formed on a substrate having a tapered surface and a wrap-around, trailing magnetic shield. The method uses a multi-layer anti-reflective coating prior to formation of the shield so that reflection from the tapered surface of the substrate does not affect the lithography of the mask used to form the trailing shield. The multi-layer antireflective coating is constructed of materials that can be left in the finished head, thereby eliminating problems associated with removal of the anti-reflective coating.
