ABSTRACT:
Methods of forming a component of a thin film magnetic head and improving the plating of a component of a thin film magnetic head are provided. The methods include the use of a high activation energy chemically amplified photoresist (CARS) that is contacted with a low pH high saturation magnetic moment plating solution to form a magnetic head component that is essentially free of plating defects. The methods find utility in hard disk drive applications, such as in the manufacture of magnetic poles for the write head of a hard disk drive.
