Latest Patents

One of Jenn Liu's latest patents is titled "Scribing Sapphire Substrates with a Solid State UV Laser with Edge Detection." This patent describes a process and system for scribing sapphire substrates by mounting a sapphire substrate that carries an array of integrated device die on a movable X-Y stage, which includes a vacuum chuck. The system directs UV pulses of laser energy at the surface of the sapphire substrate using a solid-state laser. The cutting process is carefully controlled to stop based on the edge location, preventing any impact on background elements. The laser pulses have a wavelength below about 560 nanometers, with specific energy density, spot size, and pulse duration levels established to induce ablation of sapphire.

Another patent by Jenn Liu is titled "Scribing Sapphire Substrates with a Solid State UV Laser." This patent outlines a similar process, emphasizing the importance of controlling the system to create a scribe pattern on the sapphire substrate. The overlapping of successive pulses is crucial for cutting scribe lines effectively.
