Titanium disilicide (TiSi2), as a metal silicide, plays a crucial role in microelectronics, specifically in Large Scale Combination (VLSI) circuits, because of its excellent conductivity and reduced resistivity. It significantly minimizes call resistance and enhances present transmission performance, contributing to broadband and reduced power usage. As Moore’s Regulation approaches its restrictions, the introduction of three-dimensional assimilation innovations and FinFET styles has made the application of titanium disilicide critical for preserving the efficiency of these advanced production procedures. Additionally, TiSi2 reveals 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 phase displays a tetragonal crystal structure. As a result of its lower resistivity (around 3-6 μΩ · centimeters) and greater thermal security, the C54 stage is favored in commercial applications. Different approaches can be made use of to prepare titanium disilicide, including Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). The most common method entails responding titanium with silicon, transferring titanium films on silicon substrates via sputtering or evaporation, followed by Fast Thermal Processing (RTP) to create TiSi2. This method enables exact thickness control and uniform circulation.
