Titanium disilicide (TiSi2), as a steel silicide, plays an indispensable role in microelectronics, particularly in Very Large Scale Integration (VLSI) circuits, due to its superb conductivity and low resistivity. It substantially minimizes contact resistance and enhances existing transmission performance, contributing to high speed and low power usage. As Moore’s Regulation approaches its limitations, the emergence of three-dimensional combination technologies and FinFET architectures has made the application of titanium disilicide important for maintaining the performance of these advanced manufacturing processes. Furthermore, TiSi2 reveals great potential in optoelectronic devices such as solar batteries and light-emitting diodes (LEDs), along with in magnetic memory.
Titanium disilicide exists in numerous phases, with C49 and C54 being one of the most usual. The C49 phase has a hexagonal crystal structure, while the C54 phase shows a tetragonal crystal structure. Because of its reduced resistivity (roughly 3-6 μΩ · cm) and greater thermal security, the C54 phase is chosen in commercial applications. Different methods can be used to prepare titanium disilicide, consisting of Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). The most common approach includes reacting titanium with silicon, depositing titanium films on silicon substratums through sputtering or dissipation, adhered to by Quick Thermal Processing (RTP) to form TiSi2. This technique permits precise thickness control and uniform distribution.
