Titanium disilicide (TiSi2), as a metal silicide, plays a vital role in microelectronics, especially in Very Large Range Integration (VLSI) circuits, due to its superb conductivity and low resistivity. It dramatically reduces get in touch with resistance and enhances existing transmission efficiency, adding to high speed and reduced power consumption. As Moore’s Legislation approaches its restrictions, the emergence of three-dimensional combination modern technologies and FinFET styles has made the application of titanium disilicide critical for preserving the efficiency of these innovative manufacturing processes. Additionally, TiSi2 shows fantastic possible in optoelectronic tools such as solar cells and light-emitting diodes (LEDs), along with in magnetic memory.
Titanium disilicide exists in multiple stages, with C49 and C54 being the most usual. The C49 phase has a hexagonal crystal structure, while the C54 stage exhibits a tetragonal crystal framework. Because of its reduced resistivity (roughly 3-6 μΩ · cm) and higher thermal security, the C54 stage is favored in industrial applications. Numerous methods can be utilized to prepare titanium disilicide, including Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). One of the most usual technique involves reacting titanium with silicon, transferring titanium films on silicon substrates using sputtering or dissipation, followed by Rapid Thermal Handling (RTP) to create TiSi2. This method allows for accurate thickness control and uniform distribution.
