Molybdenum Evaporation Material Description

Molybdenum (Mo) is a gray-metallic element renowned for its exceptional melting point, which is the third highest among all elements, after tungsten and tantalum. With a melting point of 2,617°C, a density of 10.2 g/cc, and a vapor pressure of 10^-4 Torr at 2,117°C, molybdenum exhibits remarkable strength and stability under high-heat conditions. Although it is found in various oxidation states in minerals, it does not exist naturally in its free form. Its robust properties make it ideal for alloying with other metals to produce corrosion-resistant materials used in tools, aircraft components, and electrical contacts.

In deposition processes, high-purity molybdenum evaporation materials are essential for achieving high-quality deposited films. TFM specializes in producing molybdenum evaporation materials with purity levels up to 99.95%, supported by stringent quality assurance measures to ensure reliable product performance.

FAQ

  • They are high‐purity substances (e.g. metals, alloys, or compounds) used in thermal or electron‐beam evaporation processes to form thin films on substrates.

  • Typically, they’re processed into a form (often ingots, pellets, or wires) that can be efficiently vaporized. Preparation emphasizes high purity and controlled composition to ensure film quality.

  • Thermal evaporation and electron-beam (e-beam) evaporation are the two main techniques, where material is heated (or bombarded with electrons) until it vaporizes and then condenses on the substrate.

  • Thermal evaporation heats the material directly (often using a resistive heater), while e-beam evaporation uses a focused electron beam to locally heat and vaporize the source material—each method offering different control and energy efficiency.

  • Key parameters include source temperature, vacuum level, deposition rate, substrate temperature, and the distance between the source and the substrate. These factors influence film uniformity, adhesion, and microstructure.

  • Evaporation generally produces high-purity films with excellent control over thickness, and it is especially suitable for materials with relatively low melting points or high vapor pressures.

  • Challenges include issues with step coverage (due to line-of-sight deposition), shadowing effects on complex topographies, and possible re-evaporation of material from the substrate if temperature isn’t properly controlled.

  • Common evaporation materials include noble metals (e.g., gold, silver), semiconductors (e.g., silicon, germanium), metal oxides, and organic compounds—each chosen for its specific optical, electrical, or mechanical properties.

  • Selection depends on desired film properties (conductivity, optical transparency, adhesion), compatibility with the evaporation process, and the final device application (semiconductor, optical coating, etc.).

  • Optimizing substrate temperature, deposition rate, and chamber vacuum are critical for ensuring that the film adheres well and forms the intended microstructure without defects.

  • Troubleshooting may involve checking the source material’s purity, ensuring stable source temperature, verifying the vacuum level, adjusting the substrate’s position or temperature, and monitoring deposition rate fluctuations.

While evaporation tends to yield very high purity films with excellent thickness control, it is limited by its line-of-sight nature. In contrast, sputtering can deposit films more uniformly on complex surfaces and is more versatile for a broader range of materials.
