Title: Innovations by Hiroshi Omine in Magnetic Head Technology

Introduction

Hiroshi Omine is a notable inventor based in Santa Clara, California. He has made significant contributions to the field of magnetic head devices, holding two patents that showcase his expertise and innovative spirit.

Latest Patents

Hiroshi Omine's latest patents include a "System for controlling a critical dimension (CD) uniformity of a magnetic head device." This patent describes systems and methods for ensuring uniformity in critical dimensions of magnetic head devices. The film stack involved in this system comprises a substrate, a magnetoresistive (MR) sensor layer, and a hard mask layer. Additionally, the system utilizes a first mask to define critical shape patterns other than the CD, allowing for precise patterning of the hard mask layer. A second mask is also employed to define the CD, enabling the formation of a mandrel pattern on the hard mask layer.

Another significant patent is the "Method of ultra-fine critical dimension patterning for magnetic head devices." This method outlines critical dimension (CD) uniformity control techniques for magnetic head devices. It includes providing a film stack with a substrate, an MR sensor layer, and a hard mask layer. The process involves patterning the hard mask layer with a first mask, forming a mandrel pattern using a second mask, and creating a sidewall spacer pattern on the mandrel's sidewalls before removing the mandrel pattern.
