Titanium Disilicide (TiSi2): A Critical Material in Semiconductor Technology
Titanium disilicide (TiSi2), as a metal silicide, plays an indispensable role in microelectronics, especially in Huge Scale Assimilation (VLSI) circuits, due to its exceptional conductivity and reduced resistivity. It dramatically decreases call resistance and boosts current transmission efficiency, contributing to broadband and reduced power intake. As Moore’s Law approaches its limits, the emergence of three-dimensional assimilation modern technologies and FinFET designs has made the application of titanium disilicide important for keeping the performance of these sophisticated manufacturing processes. In addition, TiSi2 shows terrific possible in optoelectronic tools such as solar cells and light-emitting diodes (LEDs), in addition to in magnetic memory.
Titanium disilicide exists in numerous stages, with C49 and C54 being the most usual. The C49 phase has a hexagonal crystal framework, while the C54 stage displays a tetragonal crystal framework. Due to its lower resistivity (roughly 3-6 μΩ · centimeters) and greater thermal stability, the C54 phase is preferred 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 usual technique entails responding titanium with silicon, transferring titanium films on silicon substratums using sputtering or dissipation, followed by Fast Thermal Processing (RTP) to form TiSi2. This technique enables accurate density control and uniform distribution.
