Abstract:
A method for avoiding accidental arcing, before, during and after, a sputter process for sputtering MR leads, comprising the steps of:a) providing 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) forming a first dielectric layer over said shield layer;c) forming a second dielectric layer over said first dielectric layer;d) patterning said second dielectric layer to form a MR window and an first extraneous widow in an area where a lead opening will be formed; said MR window and said exposing said first dielectric layer;e) forming a MR stripe over said first dielectric layer in said MR window;f) forming 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 window in a first direction so that said MR window is the symmetric axis of said lead openings and that one of said first or second lead opening connect said MR window and said first extraneous window being located at a tip of said first or second lead opening in said first direction;g) placing said wafer in a sputtering tool having an electrode that generates an electric field in a second direction;h) sputtering a lead layer over said resist layer and said second dielectric layer and said MR stripe;i) removing said wafer from said sputtering tool.
