Bilayer liftoff process for high moment laminate |
摘要 |
The magnetic tape recording head of the present invention is formed with magnetic poles that are comprised of a laminated NiFeN/FeN structure. The method for fabricating the magnetic poles utilizes an additive photolithographic technique including a bilayer liftoff resist. In this fabrication method magnetic pole trenches are formed in the bilayer liftoff resist such that an undercut exists in the liftoff layer. Thereafter, the laminated NiFeN/FeN structure is sputter deposited into the trench, followed by the wet chemical removal of the bilayer resist.
