Plasma-Therm Vision 410 is a 16-inch diameter parallel plate, PC-controlled, PE-CVD system for deposition of dielectric films, such as SiO2, Si3N4, SiOxNy, low-stress Si3N4. Deposition is achieved by introducing reactant gases between parallel electrodes—a grounded electrode and an RF-energized electrode. The substrate, which is placed on the grounded electrode, is typically heated to 250°C – 300°C, depending on the specific film requirements. These films are usually used for interlayer electrical insulators, chemical passivation layers, hard mask for plasma etching, and anti-reflective coatings. The stress of the nitride can be tuned by adjusting the %He in the N2+He mixture without significant ion bombardment. SF6/N2O plasma is used to clean the chamber between depositions.
