Latest Patents

Among his most recent inventions are two groundbreaking patents. The first patent details a **two-step deposition process for preventing arcs**. This method involves a unique technique of depositing tungsten (W) or titanium-tungsten (TiW) on a silicon wafer within a physical vapor deposition chamber. The process cleverly utilizes a high-pressure phase to create an electrical bridge between the wafer and the clamping ring, ensuring that no arcing occurs. Following this, a lower pressure phase ensures the formation of a high-quality conductive film.

The second patent focuses on **in-situ cleaning of a titanium target in a Ti+TiN coating process**. This innovative method enhances the deposition process by incorporating a simple cleaning step that does not require a shutter. By conducting titanium and titanium nitride (TiN) deposition in the same process chamber, Mark's approach significantly streamlines production and enhances efficiency.
