Patent ID: 7530159

Claim:
A method for fabricating a write pole for a magnetic recording head, comprising: A) providing a target P 2 pole configuration; B) providing a wafer stack; C) forming a photoresist layer on said wafer stack; D) providing a first photomask having a pattern, and positioning said photomask between said photoresist layer and a light source; E) exposing said first photomask and said photoresist to said light source such that said pattern of said first photomask is transferred to said photoresist to create a patterned photoresist having at least one photoresist channel; F) forming a layer of photoresist channel shrinking film on said patterned photoresist; G) baking said photoresist channel shrinking film to produce a reduced width photoresist channel in an expanded photoresist; H) removing said photoresist channel shrinking film; J) electroplating a P 2 pole tip within said reduced width channel of said expanded photoresist to form a P 2 pole tip; K) comparing said P 2 pole tip with said target P 2 pole configuration to identify distortions; L) using said identified distortions to produce a distortion-corrected photomask; M) using said distortion corrected photomask to produce a distortion-corrected expanded photoresist; and N) using said distortion-corrected expanded photoresist to produce a distortion-corrected P 2 pole tip.
