Title: Innovations of Inventor Xiao Liu
Introduction
Xiao Liu is a prominent inventor based in Fairfax Station, VA (US). He has made significant contributions to the field of materials science, particularly in the development of advanced thin films. With a total of 8 patents to his name, Liu's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
Among his latest patents, Liu has developed a method for producing high-temperature sputtered stoichiometric amorphous aluminum oxide. This process involves placing a substrate into a chamber with an aluminum target, which is then sputtered under controlled conditions. The chamber is evacuated to a base pressure of about 7×10 Torr or lower, while maintaining the substrate temperature. The method also includes flowing argon gas to backsputter the aluminum target and to presputter the target before sputtering aluminum onto the substrate in the presence of argon and oxygen gases.
Another notable patent is for producing high-temperature sputtered stoichiometric titanium nitride thin films. In this method, a substrate is placed in a sputtering chamber with a titanium target. The substrate temperature is controlled between room temperature and about 800°C. The chamber is evacuated to a base pressure of 2×10 Torr or lower, and the titanium target is presputtered under argon gas flow. The titanium is then sputtered onto the substrate in the presence of nitrogen and argon gas flows, ensuring that the film is nitrogen-saturated.
