Video Transcript ----- When it comes to producing thin metal films for solar cells, sample preparation for microscopy techniques such as SEM, electrical contacts and much more,  thermal evaporation is one of the most well-established physical vapour deposition techniques. It can be used to deposit chrome, aluminium, silver, gold, and many other metals onto a range of substrates. But how does thermal deposition work? The process begins by placing two materials in a vacuum chamber: One to be coated, known as the substrate. And the other to coat the substrate, known as the evaporant or “source” material. The substrate is held at the top of the chamber, while the evaporant is placed at the bottom. Once the required pressure is reached, an electrical current is passed through a filament, which holds the source material, raising the temperature of the material via resistive heating until it evaporates The vapour cloud generated by this source material travels through the chamber and sticks to the substrate as a thin film coating. If you’re working with materials with particularly high melting points, you may require e-beam evaporation instead. However, thermal evaporation by resistive heating is still your best option if you need to create films of thickness beyond a few microns or require a more cost-effective solution. if you need a system to carry out thermal evaporation, then our HEX Series at Korvus Technology is ideal. It’s a highly modular deposition system with multiple application options and techniques. The TES thermal evaporation source is just one of the PVD techniques you can choose with the HEX The TES is a versatile option, because the “filament”, which holds your evaporant material, can come in many different forms, depending on your type of material.  These can include boats, basket heaters, or crucible heaters. Where most thermal evaporator PVD systems are fixed format, the HEX with TES can easily be upgraded to add other techniques at a later date If you're interested in learning more about the HEX and its thermal deposition functionality, get in touch today.
