Title: Nathan A. Aldrich: Innovator in Polishing Uniformity

Introduction

Nathan A. Aldrich is a notable inventor based in Pflugerville, TX (US). He has made significant contributions to the field of semiconductor manufacturing, particularly in the area of polishing uniformity. With a total of 2 patents, Aldrich has developed innovative methods that enhance the efficiency and effectiveness of metal polishing processes.

Latest Patents

Aldrich's latest patents focus on a method of implementing polishing uniformity and modifying layout data. This method identifies areas of low overburden that degrade metal polish nonuniformity. It also describes a technique for modifying these areas to increase their overburden, thereby slowing down the metal polish rate and improving overall polish uniformity. The resulting structure forms slots in groups of functional lines, such as bus lines, when the functional lines have a density that exceeds a predetermined amount. In one embodiment, an area of the wafer has a maximum width of 1.5 microns in regions with a feature density greater than approximately 50 percent. These methods and resulting structures create a higher feature density, which ultimately increases polishing uniformity.
