Technology Overview: Disilicide Materials & Properties
Disilicides—compounds containing two silicon atoms bonded to a metal—are playing an increasingly significant role in microelectronics fabrication as the industry advances toward next-generation device architectures in 2025 and beyond. Among these, molybdenum disilicide (MoSi2), tungsten disilicide (WSi2), and titanium disilicide (TiSi2) are especially valued for their unique combination of high electrical conductivity, robust thermal stability, and compatibility with silicon-based processing technologies. These materials are utilized primarily as contact and interconnect layers, barrier materials, and gate electrodes in complementary metal-oxide-semiconductor (CMOS) device fabrication.
A critical advantage of disilicide materials lies in their low resistivity, which helps mitigate the parasitic resistance encountered as device geometries continue to shrink. For example, TiSi2 and WSi2 offer resistivities as low as 13–60 μΩ·cm, making them suitable for sub-10 nm node technologies. Their thermal stability, withstanding temperatures above 800°C, ensures integrity during high-temperature processing steps such as annealing and dopant activation. MoSi2, in particular, is prized for its oxidation resistance and is being explored in advanced logic and memory applications, including gate-all-around (GAA) FETs and 3D NAND structures.
The fabrication of disilicide layers typically involves techniques such as chemical vapor deposition (CVD), physical vapor deposition (PVD), and, increasingly, atomic layer deposition (ALD) for conformal coatings on 3D architectures.

Fabrication Processes: Innovations and Challenges
Disilicide-based microelectronics fabrication has emerged as a critical avenue for advancing device performance, reliability, and scaling as the industry moves deeper into the sub-5 nm technology nodes. In 2025, the integration of transition metal disilicides—most notably tungsten disilicide (WSi2), molybdenum disilicide (MoSi2), and titanium disilicide (TiSi2)—continues to gain traction for applications in gate electrodes, interconnects, and contact layers due to their low resistivity, high thermal stability, and robust diffusion barrier properties.
Recent fabrication innovations focus on atomic-layer deposition (ALD) and chemical vapor deposition (CVD) methods, which offer precise thickness and stoichiometry control essential for sub-nanometer architectures. For instance, major equipment manufacturers such as Lam Research and Applied Materials have actively developed advanced ALD and CVD platforms tailored to deposit uniform disilicide films at low temperatures, mitigating challenges related to interfacial silicide formation and substrate compatibility. This is particularly relevant as device geometries shrink and 3D architectures such as gate-all-around (GAA) FETs become prevalent.
A significant challenge in 2025 remains the phase stability and sheet resistance of disilicide contacts under thermal cycling, which is crucial for logic and memory devices with aggressive thermal budgets. Process optimization—including pre-clean steps, selective deposition, and post-deposition annealing—has shown promising results in reducing contact resistance and silicide agglomeration, as reported by collaborative efforts between semiconductor foundries and materials suppliers like TOK and Entegris.
Another frontier is the integration of disilicides with emerging materials such as SiGe, Ge, and compound semiconductors. The need for defect-free, abrupt interfaces and minimal interdiffusion is pushing the industry to refine in-situ process monitoring and surface passivation strategies. Equipment providers are incorporating real-time metrology and feedback control into deposition modules, further enhancing reliability and yield.

The collaboration between materials developers, equipment vendors, and device manufacturers is expected to accelerate, with leading industry consortia such as SEMI facilitating standardization and knowledge exchange. As the industry targets ever-smaller nodes and heterogeneous integration, disilicide process innovations will remain a linchpin for microelectronics advancement through the late 2020s.
Performance Advantages Over Conventional Materials
The ongoing evolution of microelectronics fabrication is driven by the need for improved device speed, reduced power consumption, and enhanced thermal stability. Within this context, disilicide-based materials—especially those incorporating molybdenum disilicide (MoSi2) and tungsten disilicide (WSi2)—are emerging as superior alternatives to conventional materials like polysilicon and standard silicides for critical microelectronic applications. In 2025, this shift is marked by several performance advantages that are gaining traction in the semiconductor industry.
A principal advantage of disilicides lies in their significantly lower electrical resistivity. For example, MoSi2 and WSi2 exhibit bulk resistivities as low as 2–4 μΩ·cm, compared with polysilicon’s much higher values. Lower resistivity translates directly into faster signal propagation and reduced RC-delay, which is critical as device nodes shrink below 5 nm. Major foundries and integrated device manufacturers have begun integrating disilicides for gate, contact, and interconnect layers to maximize performance in logic and memory chips Intel, TSMC.
Thermal stability is another key area where disilicide-based materials outperform conventional choices. Both MoSi2 and WSi2 maintain their structural and electrical integrity at temperatures exceeding 900°C, which is vital for advanced CMOS and memory fabrication involving high-temperature processing steps. This robustness minimizes diffusion-related degradation and preserves device reliability throughout complex manufacturing cycles. Manufacturers of advanced wafer processing equipment are tailoring their toolsets to support the integration of these refractory materials Lam Research, Applied Materials.
Beyond conductivity and stability, disilicide layers offer excellent compatibility with current back-end-of-line (BEOL) and front-end-of-line (FEOL) processes. Their ability to form uniform, pinhole-free films by chemical vapor deposition (CVD) or sputtering supports further scaling and 3D integration, essential for next-generation logic and memory architectures. In 2025 and beyond, this is anticipated to accelerate adoption in high-density applications such as high-bandwidth memory (HBM) and advanced logic nodes Samsung Electronics.
Looking forward, the outlook for disilicide-based microelectronics fabrication is highly promising. Industry roadmaps and pilot line demonstrations indicate that the adoption of MoSi2 and WSi2 will continue to expand, driven by the relentless push for smaller, faster, and more efficient semiconductor devices.
