Abstract:
A method for fabricating a magnetic head comprising the steps of:fabricating a substrate layer of said magnetic head upon which a photolithographically fabricated component is to be formed; depositing a carbon bottom antireflection coating (BARC) coating upon said substrate layer; depositing a photoresist layer upon said carbon BARC coating; exposing said photoresist layer to light energy in a photolithographic exposure step; developing and removing photoresist material deposited above said carbon BARC coating; removing said carbon BARC coating in areas where said photoresist has been removed; forming said component in areas where said carbon BARC coating has been removed; removing remaining portions of said photoresist layer; removing remaining portions of said carbon BARC coating; and fabricating further components of said magnetic head.
