Low refractive index silicon oxide coatings at room

Low refractive index silicon oxide films were deposited using atmospheric-pressure He/SiH 4 /CO 2 plasma excited by a 150-MHz very high-frequency power. Significant increase in deposition rate at room temperature could prevent the formation of dense SiO 2 network, decreasing refractive index of the resulting film effectively. As a result, a silicon oxide film with the lowest refractive index
