Latest Patents

One of Brown's latest patents is a method to produce a highly transparent hydrogenated carbon protective coating for transparent substrates. This invention involves a physical vapor deposition (PVD) chamber designed for depositing a clear hydrogenated carbon film, such as hydrogenated diamond-like carbon. The chamber is configured to maintain a vacuum condition and features an aperture on its sidewall. A plasma cage with an orifice is attached to the sidewall, allowing for the overlap of the orifice and aperture. Inside the plasma cage, two sputtering targets are positioned on cathodes, oriented opposite each other to sustain plasma between them. The plasma sputters material from the targets, which then passes through the orifice and aperture to land on the substrate. The substrate is continuously moved in a pass-by fashion during this process, ensuring an efficient coating application.
