Abstract

Compound layers, such as metal silicon nitrides, are formed by ALD or CVD from precursors with incompatible reaction temperature ranges. The substrate is held at a temperature within the lower reaction temperature range (e.g., that of a metal precursor). The low-temperature precursor and its reactant react to form an ALD monolayer or thin CVD layer. The high-temperature precursor and its reactant are pulsed in the chamber, and the substrate is irradiated with ultraviolet light. The ultraviolet light adds energy to the system to overcome the reaction barrier despite the substrate temperature being below the minimum reaction temperature of the high-temperature precursor.
