Titanium disilicide (TiSi2), as a steel silicide, plays a vital role in microelectronics, specifically in Very Large Range Combination (VLSI) circuits, due to its outstanding conductivity and low resistivity. It substantially reduces get in touch with resistance and enhances existing transmission effectiveness, contributing to broadband and low power consumption. As Moore’s Law approaches its limitations, the appearance of three-dimensional integration technologies and FinFET designs has made the application of titanium disilicide crucial for maintaining the performance of these advanced production procedures. In addition, TiSi2 shows wonderful prospective 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 one of the most typical. The C49 stage has a hexagonal crystal structure, while the C54 stage displays a tetragonal crystal structure. Because of its lower resistivity (roughly 3-6 μΩ · centimeters) and greater thermal stability, the C54 stage is favored in commercial applications. Various techniques can be made use of to prepare titanium disilicide, consisting of Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). One of the most typical method entails reacting titanium with silicon, transferring titanium films on silicon substrates by means of sputtering or evaporation, adhered to by Fast Thermal Processing (RTP) to develop TiSi2. This method permits exact density control and consistent distribution.
