WebFeb 02, 2012 Microwave plasma oscillates electrons, which in turn produces ions by colliding with gas atoms and molecules. A schematic representation of a microwave plasma reactor manufactured by ASTEX is shown in Fig. 8.8. However, the deposition area is restricted for a microwave CVD reactor. WebThis is an ASTeX microwave plasma reactor used for a wide range of materials synthesis by CVD. The reactor is equipped with 1500 Watts MW power supply with deposition areas as high as 4 inch2. Using microwaves as the gas phase excitation source and different gas phase chemistries we were able to synthesize a variety of materials.
