Titanium disilicide (TiSi2), as a metal silicide, plays a vital duty in microelectronics, particularly in Huge Scale Assimilation (VLSI) circuits, as a result of its outstanding conductivity and reduced resistivity. It substantially decreases contact resistance and improves current transmission performance, contributing to broadband and low power consumption. As Moore’s Legislation approaches its restrictions, the appearance of three-dimensional integration modern technologies and FinFET styles has made the application of titanium disilicide critical for keeping the efficiency of these sophisticated manufacturing procedures. In addition, TiSi2 shows excellent possible in optoelectronic devices such as solar cells and light-emitting diodes (LEDs), as well as in magnetic memory.
Titanium disilicide exists in several phases, with C49 and C54 being the most usual. The C49 stage has a hexagonal crystal framework, while the C54 stage exhibits a tetragonal crystal framework. Because of its reduced resistivity (about 3-6 μΩ · centimeters) and greater thermal security, the C54 stage is chosen in industrial applications. Various methods can be used to prepare titanium disilicide, including Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). The most common technique involves responding titanium with silicon, depositing titanium movies on silicon substratums via sputtering or dissipation, adhered to by Rapid Thermal Processing (RTP) to develop TiSi2. This approach permits precise density control and uniform circulation.
