  1、 Basic performance requirements for titanium target materials ① Purity: As one of the main performance indicators of target materials, purity has a crucial impact on the performance of thin films. In practical applications, the requirements for the purity of target materials vary by industry. For example, in the microelectronics industry, with the continuous increase in silicon wafer size and the continuous decrease in wiring width, the requirements for target purity are also constantly increasing. Previously, a target purity of 99.995% could meet the process requirements of 0.35um IC, but now preparing 0.18um lines requires a target purity of 99.999% or even 99.9999%. ② Impurity content: Impurities in the solid of the target material and oxygen and water vapor in the pores are the main sources of pollution for depositing thin films. Therefore, the requirements for impurity content of target materials for different purposes are also different. For example, pure aluminum and aluminum alloy targets used in the semiconductor industry have special requirements for alkali metal content and radioactive element content. ③ Density: In order to reduce the pores in the solid target material and improve the performance of sputtered films, it is usually required that the target material has a high density. The density of the target material not only affects the sputtering rate, but also affects the electrical and optical properties of the thin film. In addition, increasing the density and strength of the target material can better withstand the thermal
