Inverted Top-Hat Trough Boat

Choose a heater shape that best matches the substrate's area requirements and the characteristics or form of material you plan to heat. When heating the same material multiple times, these boat heaters are sometimes satisfactory for more than a single-time use.

The Part No. listed in the ordering table carries the boat material code. "MO" indicates molybdenum, "TA" indicates tantalum, and "W" indicates tungsten.

Don’t forget to order your evaporation materials.
