With three patents to his name, Nohava has developed innovative methods that enhance the performance and reliability of these technologies.

Latest Patents

One of Nohava's latest patents is focused on saw debris reduction in MEMS devices. This invention involves an improved MEMS device and a novel method of manufacturing it. The process includes forming channels in a first substrate around several MEMS device areas. Seal rings are then applied surrounding these areas, and a second substrate is attached. This innovative design ensures that saw debris particles are kept away from the MEMS device areas, thereby improving overall functionality.

Another notable patent by Nohava addresses protective side wall passivation for VCSEL chips. The method disclosed involves sealing or passivating the edges of chips at the wafer level before they are cut into individual die. By oxidizing the edges of the die, particularly on aluminum-bearing layers, the invention creates a stable native oxide that significantly increases resistance to environmental oxidation. This enhances the durability of the VCSEL chips, ensuring that each die features a protective oxide layer on its side surfaces after cutting.
