Vertical annealing furnace

○ Product Details

1. Equipment Overview:

The vertical annealing furnace system is applicable to integrated circuits, discrete components, POWER, MEMS and other fields, suitable for high-temperature dry/wet oxidation, DCE oxidation, nitridation, diffusion, GPP, annealing, alloying and other processes for 6-12 inch wafer chips.

 The annealing process is carried out under medium-low temperature conditions by introducing inert gas (N2) to eliminate crystal defects and damage at the wafer interface, optimizing the quality of the wafer interface.

The system is a vertical single-chamber furnace tube with highly automated process control. It mainly includes the main unit, power cabinet, gas cabinet, heating system, transmission system and other components.
