In the realm of high-tech fields, the titanium target plays a critical role, particularly in thin film deposition processes. This material, made mainly via magnetron sputtering or physical vapor deposition (PVD) techniques, deposits thin films with specific functions or decorative effects onto substrates. Titanium targets, made from pure titanium or its alloys, possess specific shapes and fine surfaces, which are utilized in physical evaporation or sputtering processes.
There are primarily two preparation methods for titanium targets: casting method and powder metallurgy method.
Casting Method
The casting method uses vacuum melting technology to melt high-purity titanium raw materials, which are then cast into ingot blanks. After undergoing heat treatment and rolling or forging, the ingot blanks are processed by machine tools to obtain the titanium target. This method features simple equipment and a direct preparation process but requires strict vacuum conditions and may encounter issues like internal segregation and coarse structures.
Powder Metallurgy Method
The powder metallurgy method is a novel technique capable of producing titanium targets with uniform and defect-free microstructures, although it involves complex equipment and higher costs.
The performance requirements of a titanium target include purity, microstructure, welding performance, and dimensional accuracy. Purity is one of the main performance indicators of a titanium target, significantly impacting the characteristics of the thin film.
Titanium targets have wide applications in the electronics field, such as in the sputtering coating process for manufacturing displays on mobile phones, computers, and other electronic devices.
In semiconductor manufacturing, titanium and its compounds (e.g., titanium nitride and titanium oxide) are commonly used to create interface layers, soldering aids, barrier layers, etc. In wafer manufacturing, they are mainly used for metal sputtering, typically employing PVD techniques for coating.
Additionally, titanium targets are extensively used in decorative coating fields, such as glass decorative coatings and wheel hub decorative coatings, as well as in creating decorative layers for jewelry, watches, eyeglass frames, tools, and home decor.
The development prospects for titanium targets are exceedingly broad. With the constant growth of the global titanium target market, advancements in innovative manufacturing techniques, environmental sustainability, wireless communications, new energy fields, and applications in the pharmaceutical and medical industries, along with the rise of intelligent and digital advancements, will drive progress in the titanium target industry.
As technology develops, new techniques like powder metallurgy and 3D printing will further enhance the production and processing efficiency of titanium targets, improving their microstructure and performance.
