Why is the temperature of physical vapor deposition high?

The difference between chemical vapor deposition and chemical vapor deposition lies in temperature. The chemical vapor deposition temperature is high and the deposition bonding force is strong, but the hardness of the matrix decreases, while the physical vapor deposition temperature is low, which does not affect the hardness of the matrix.
