Abstract
An injecting assembly includes a nozzle that is formed with a mixture channel, a mixture opening communicating with the mixture channel, a shaper channel, and a shaper opening communicating with the shaper channel. A mixture of a precursor and a supercritical fluid (SCF) passes through the mixture channel. Waves of the mixture are periodically injected toward a surface of a substrate at the mixture opening. A stream of a shaping fluid flows through the shaper channel and is injected toward the substrate at the shaper opening. The stream of the shaping fluid confines the waves of the mixture. Molecules of the precursor penetrate into the substrate by impact of the wave fronts reaching the surface of the substrate. The molecules of the precursor can react with molecules of a material of the substrate to improve surface properties of the substrate.
