Patent ID: 8273233

Claim:
A method of forming a write pole in a perpendicular magnetic recording head, comprising: (a) forming an opening in a mold forming layer having a top surface, said opening has a bottom that exposes a portion of a substrate and has sidewalls that extend from the top surface to said substrate; (b) forming a conformal Ru seed layer along the top surface and sidewalls, and on the bottom of the opening in a deposition chamber; (c) depositing an auxiliary layer on the seed layer in the deposition chamber wherein said auxiliary layer conforms to a top surface of the seed layer and has a composition represented by Co x Fe y Ni z or oxides or alloys thereof wherein each of x, y, and z is from 0 to 100 atomic % and x+y+z=100 atomic %; (d) removing all or a portion of the auxiliary layer in an electroplating solution; and (e) performing an electroplating process in said electroplating solution that deposits a magnetic material which fills said opening.
