New Materials through Thin Film Engineering.
Sigma VaporPhase™ technology is a breakthrough process for depositing functional layers ranging in thickness from a few, to a few hundred, nanometers. Layers can be applied to films, fabrics, paper, and metal foils and can be used to create multi-layer composite materials for the production of high aspect ratio pigments, energy storage devices, and barrier materials.
