Title: **Innovator Sheng Liu: Pioneering Advances in Post Arrays and Metal Gratings**

Introduction

Sheng Liu, a distinguished inventor based in Harrison, NJ, has made significant contributions to the field of materials science and engineering. With a portfolio of five patents, Liu's work primarily focuses on innovative methods for creating advanced structures, particularly in the realms of post arrays and metal gratings.

Latest Patents

Among his notable inventions, Liu's patents include cutting-edge methods for the formation of post arrays and metal gratings. One of his latest patents describes a method involving the formation of a mask material layer on a first layer's surface, followed by a patterning process to create a mask feature. This method induces mass transport of the mask material to yield a modified mask feature, eventually transferring its profile into the first layer to create a structured first layer with specific angles.

Another significant patent details the methodology behind creating short pitch metal gratings. This process begins with a dielectric material grating, from which metal is deposited, maintaining a constant thickness. Portions of the metal layer are then selectively removed to form a metal grating with precise dimensional attributes, including a pitch of 200 nm or less and an impressive aspect ratio of 10-to-1 or more.
