在COC过程中磁化死层界面最小化的方法

Method for minimizing magnetically dead interfacial layer during COC process
Abstract:
A method for applying a protective layer to an electronic device such as the ABS of a slider, magnetic head, etc. for reducing paramagnetic deadlayer thickness includes selecting an etching angle for minimizing formation of a paramagnetic deadlayer at an interface of an electronic device and an adhesive layer subsequently formed on the electronic device, etching a surface of an electronic device at the selected angle, the selected angle being less than about 75 degrees from an imaginary line extending perpendicular to the surface, forming an adhesive layer on the etched surface of the electronic device, and forming a protective layer on the adhesive layer. A magnetic head formed by the process is also disclosed.
