Resistive Thermal Evaporation Boats

RD Mathis Company Molybdenum Boat Sources

About Boat Source Design

At their core, evaporation boats are made to hold and heat up material. These come with varying dimples or troughs, depending on the capacity needed.

 

Other design features can enhance the deposition process. Bends provide relief from thermal expansion. Notches allow heat to be focused into specific areas. These unique geometries allow flexibility for different processes.

 

Ask About Custom Modifications

With short lead times and affordable prices due to flexible tooling, we have offered many specialized boats to customers.

 

Our selection of boats is easily adaptable to different lengths, bends & other features needed. Let us know how we can help.

  • Technical Tip

Aluminum Evaporation

Thin films of aluminum are widely used for numerous applications, such as optical coatings making use of its reflective properties.

 

Although aluminum does not have problems like spitting, keep in mind the following when depositing aluminum:

  1. Molten aluminum will wet to surfaces and migrate out of the evaporation area.
  2. Material selection is important to prevent the aluminum from corroding thermal evaporation sources.

 

S47

To optimize aluminum deposition, choose tungsten as the boat or coil material with large thicknesses, such as an S47 boat.

 

For crucible heating, boron nitride composite (BNC) is an excellent choice to prevent the molten aluminum from wetting to the side walls.

 

Cool Lip Crucible

Cool lip style crucibles are particularly designed for aluminum evaporation, with extended walls inhibiting migration.

 

This aluminum evaporation material comes in many forms, including pellets, wire, and also cane or clip shapes.
