Thermal Evaporation Solutions
Thermal evaporation is a common method of physical vapor deposition (PVD). It is one of the simplest forms of PVD and typically uses a resistive heat source to evaporate a solid material in a vacuum environment to form a thin film. The material is heated in a high vacuum chamber until vapor pressure is produced. The evaporated material, or vapor stream, traverses the vacuum chamber with thermal energy and coats the substrate.

Thermal evaporation deposits both metals and nonmetals, including aluminum, chrome, gold, indium, and many others. This thin film deposition method is used most commonly for applications involving electrical contacts, by depositing such single metals as silver or aluminum. More complex applications include the co-deposition of several components and can be achieved by carefully controlling the temperature of individual crucibles.

Thermal evaporation can be applied to deposit metallic contact layers for thin film devices such as OLEDs, solar cells and thin-film transistors. In addition, this technique can be used to deposit thick indium layers for wafer bonding.

To better achieve consistent, high-quality results, Denton Vacuum controls the rate of deposition using quartz crystal rate sensor, temperature or optical monitoring systems (OMS).

GSL-1800X-ZF4 Evaporation Coating Instrument

GSL-1800X-ZF4 evaporation coating instrument is a high-vacuum evaporation coating instrument, which is especially suitable for vapor deposition of metal films sensitive to oxygen (such as Ti, Al, Au, etc.). It can also vaporize various oxide materials. This machine is equipped with 4 evaporation heating boats, and each evaporation boat is equipped with a baffle. If some configurations are changed, the evaporation coating of organic materials can be realized, which can meet the research requirements of light-emitting devices and organic solar cells. It is an experimental device with ideal coating effect and high cost.
