Titanium disilicide (TiSi2), as a metal silicide, plays an indispensable role in microelectronics, especially in Huge Scale Assimilation (VLSI) circuits, due to its superb conductivity and low resistivity. It significantly lowers get in touch with resistance and improves current transmission performance, adding to broadband and reduced power usage. As Moore’s Regulation approaches its limitations, the introduction of three-dimensional assimilation innovations and FinFET styles has made the application of titanium disilicide important for maintaining the efficiency of these sophisticated production procedures. In addition, TiSi2 shows great possible in optoelectronic devices such as solar cells and light-emitting diodes (LEDs), as well as in magnetic memory.
Titanium disilicide exists in multiple stages, with C49 and C54 being the most typical. The C49 stage has a hexagonal crystal structure, while the C54 stage displays a tetragonal crystal framework. Because of its reduced resistivity (around 3-6 μΩ · centimeters) and higher thermal stability, the C54 phase is liked in industrial applications. Different methods can be utilized to prepare titanium disilicide, including Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). The most common approach entails reacting titanium with silicon, transferring titanium films on silicon substrates through sputtering or dissipation, adhered to by Quick Thermal Handling (RTP) to develop TiSi2. This technique allows for exact thickness control and consistent distribution.
