For coatings requiring larger source volumes, folded boats are an option. These are similar to standard boats, but feature higher sidewalls.
Box sources enable higher capacities while also introducing a system of baffles to reduce pinhole defects on a coating. When the vapor stream exits the box, it follows an indirect path through these baffles that acts as a filter for particulates.
The chimney of a baffled box source can be used to direct vapor in other directions, such as for sideways and downward depositions.
Thin films of silver are used in various applications: optical, semiconductor, solar, and even decorative coatings.
Compared to other evaporation materials, silver evaporates well and is non-corrosive at elevated temperatures.
Silver deposition can be easily done using boat sources. For boat material, molybdenum and tantalum are our recommended choices.
Optimizing silver depositions varies on factors such as capacity, mounting bracket set-up, and required power.
Boats are offered in many shapes, such as different dimples (round vs. elongated) or step geometry, which helps absorb deformation from thermal expansion.
To make sure your desired capacity is compatible with your power source, R.D. Mathis Company provides a power requirement table for each part.

The successful use of thin films marks a potential turning point in the development of nuclear clocks. Using thin-film technology in nuclear clocks is commensurate with semiconductors and photonic integrated circuits.
