High Vacuum Single chamber Thermal Evolution System

I. Introduction
The High Vacuum Single-chamber Thermal Evaporation System is a multi-source organic-inorganic thermal generation system with a single-chamber circularstructure, which is mainly used for the research of EL OEL molecular organic electroluminescent device films, as follows:

1. The system adopts a structure featuring single-chamber circular and front-open cover.
2. The sample stage can be applied with a mask.
3. Sample size: 100×100mm; (4X4”)
4. 2 installation ports of imported quartz crystal oscillator probe are reserved in the growth chamber;
5. The growth chamber is equipped with 2 organic beam source furnaces, 2 sets of evaporation power supply can be equipped with evaporation power supply, , and temperature control can be carried out through the imported temp. controller.
6. The growth chamber vacuum obtaining system uses turbo molecular pump (600L/S) + mechanical pump (9L/S) for pumping;
7. The vacuum chamber components and equipped parts are all made of high-quality stainless-steel material, adopting the technique of argon-arc welding, and the surface treatment is made through the most advanced electrochemical polishing passivation process in China.

II. the main components and technical performance of the system
The ultimate vacuum of the growth chamber is ≤6×10^-5 Pa; the pumping speed can reach 6×10^-4Pa in 40 minutes.
