Abstract

Certain example embodiments of this invention relate to techniques for converting sputter-deposited TiNx or TiOxNy layers into TiOx layers via activation with electromagnetic radiation. An intermediate layer including TiOxNy, 0<y≤1 is formed on a substrate. The intermediate layer is exposed to the radiation, which is preferentially absorbed by the intermediate layer in an amount sufficient to heat the intermediate layer to a temperature of 500-650 degrees C. while keeping the substrate at a significantly lower temperature. A flash light operated with a series of millisecond or sub-millisecond length pulses may be used in this regard. The converting removes nitrogen from, and introduces oxygen into, the intermediate layer, causing the layer to expand beyond its initial thickness. At least some of the final layer may have an anatase phase, and it may be photocatalytic. These layers may be used in low-maintenance glass, antireflective, and/or other applications.
