Abstract

The process of depositing TiN film on glass substrate is one chemical vapor deposition process, during which the distance between the nozzle for admitting reaction gas and the glass substrate is regulated so as to control the resistivity, surface shape, optical performance, etc of the TiN film deposited on the glass substrate. Compared with traditional method of regulating reaction temperature and reactant flow rate, the method of the present invention is simple and practical.

Description

technical field [0001] The invention relates to a method for depositing a TiN thin film on a glass substrate. Background technique [0002] With the rapid development of science and technology and economy in the world, the consumption of energy is increasing day by day, which makes the problem of energy crisis increasingly prominent. As a national strategic issue, energy conservation has attracted widespread attention from all over the world. The development of architectural technology has made the proportion of glass in buildings more and more large, and even some high-rise buildings have adopted the structure of all-glass exterior walls in order to obtain a beautiful and elegant modern architectural aesthetic effect. Ordinary colorless glass is a good building material. Using it as a window is both beautiful and practical. It can pass through about 90% of solar radiation, but it also passes through near-infrared and mid-to-far infrared rays while it passes through visible ...
