With a total of two patents to his name, Dere's work has implications for various applications in the electronics industry.
Latest Patents
One of Dan Dere's latest patents focuses on a process and system for scribing sapphire substrates using a solid-state UV laser. This innovative method involves mounting a sapphire substrate, which carries an array of integrated device die, on a movable X-Y stage equipped with a vacuum chuck. The process directs UV pulses of laser energy at the surface of the sapphire substrate, utilizing a solid-state laser. The laser pulses have a wavelength below about 560 nanometers, with a preferred range between 150 and 560 nanometers. The energy density, spot size, and pulse duration are carefully calibrated to induce ablation of the sapphire material. By controlling the system and moving the stage with a stationary beam path, the pulses create a scribe pattern on the sapphire substrate, allowing for precise cutting of scribe lines.
