Angstrom Engineering Amod Thermal Evaporators

We carry five thin film deposition systems from Angstrom Engineering for thermally depositing a wide range of materials including metals, organic and inorganic small molecules. The deposition rate is controlled using quartz crystal sensors to ensure consistent, high-quality film formation.

Angstrom Engineering Amod Sputter Deposition

Our two systems are configured to support two types of vacuum sputter deposition: RF sputtering, DC sputtering. Each of these deposition methods uses a process sputter gas, which is usually an inert gas like argon with reactive gases added for certain processes.

Angstrom Engineering Amod e-Beam Deposition

We are using our e-Beam deposition system to deposit thick films of all kinds of metals, and many metal oxides for solar cell applications.
