Abstract:
A MR lead structure for avoiding accidental arcing before, during and after, a sputter process for sputtering MR leads, comprising:a) a wafer with an overlying shield layer, said wafer having a head area; said head area divided by an ABS line which defines a kerf side area and a slider side area; b) a first dielectric layer over said shield layer; c) a second dielectric layer over said first dielectric layer; d) said second dielectric layer having a MR window overlying said ABS line and a first extraneous widow; e) a MR stripe over said first dielectric layer in said MR window; f) a resist layer over said second dielectric layer and said MR stripe; said resist layer having first and second lead openings that define two leads; said lead openings extend from said MR window in a first direction so that said MR window is the geometric center of said lead openings; wherein said first extraneous window is in an area where one of said first and second lead openings is formed in said resist layer; g) first and second leads on said second dielectric layer and said MR stripe and on said first dielectric layer in said MR window and said first extraneous window; said first and second leads extend from said MR window in a first direction so that said MR window is the geometric center of said first and second leads.
