Problems solved by technology

The preparation process conditions, such as tin content in the target, deposition rate, substrate temperature, sputtering power, and subsequent annealing treatment, all have a great impact on the photoelectric properties of the ITO thin film; however, the existing technology on the glass substrate The optical properties of the ITO film prepared at low temperature are poor, the film oxidation is incomplete, and the structure is incomplete; especially for the crystal structure and resistance of the ITO film under different temperature conditions, the temperature cannot be accurately and effectively adjusted to control the uniformity of the resistance, which reduces the ITO. The product quality and production efficiency of the film increase the production cost and affect the service life of the display and the instrument; it is the bottleneck in the production and development of this field and cannot meet the needs of users and the market
