Title: Innovations by Elizabeth Ann Brinkman

Introduction

Elizabeth Ann Brinkman is a notable inventor based in Santa Clara, CA (US). She has made significant contributions to the field of magnetic write heads, holding a total of 3 patents. Her work focuses on improving the manufacturing processes and performance of magnetic write poles.

Latest Patents

One of her latest patents is titled "Method for manufacturing a magnetic write pole with a consistent bevel angle." This innovative method enhances the uniformity of the write pole and controls the bevel angle through a damascene process. The process involves forming a trench in a RIEable fill layer, with an adhesion layer placed only outside the trench. A seed layer is deposited into the trench, followed by a non-magnetic gap layer and electroplating of a magnetic material. A chemical mechanical polishing process is then performed, resulting in a magnetic write pole within the trench. The design prevents de-lamination during polishing while avoiding oxidation-related issues.

Another significant patent is "Substrate nitrogen plasma treatment for softer CoFe main pole writer formation." This patent describes a magnetic head that includes a non-magnetic gap layer in a trench, a pole seed layer above it, and a pole layer of magnetic material. Notably, at least one of these layers contains nitrogen, which contributes to the overall performance of the magnetic head.
