Titanium disilicide (TiSi2), as a metal silicide, plays an essential role in microelectronics, particularly in Huge Scale Integration (VLSI) circuits, because of its superb conductivity and low resistivity. It dramatically reduces get in touch with resistance and enhances existing transmission performance, contributing to broadband and low power usage. As Moore’s Legislation approaches its limitations, the development of three-dimensional integration modern technologies and FinFET styles has made the application of titanium disilicide essential for maintaining the efficiency of these advanced manufacturing procedures. In addition, TiSi2 shows great potential in optoelectronic gadgets such as solar cells and light-emitting diodes (LEDs), along with in magnetic memory.
Titanium disilicide exists in numerous phases, with C49 and C54 being the most typical. The C49 phase has a hexagonal crystal framework, while the C54 stage displays a tetragonal crystal structure. Because of its lower resistivity (about 3-6 μΩ · cm) and higher thermal security, the C54 phase is favored in commercial applications. Various methods can be utilized to prepare titanium disilicide, consisting of Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). The most usual technique involves responding titanium with silicon, transferring titanium movies on silicon substratums by means of sputtering or evaporation, complied with by Rapid Thermal Processing (RTP) to develop TiSi2. This method allows for accurate density control and uniform circulation.
