  • Publication number: 20060124939
    Abstract: A simplified manufacturing process for massive production of LEDs that have superior light emitting efficiency and superior heat discharging efficiency. The method employs a laser lift-off technique instead of the flip-chip bonding technique and it does not require a photolithography process, thereby substantially reducing the process steps and enhancing the heat discharging efficiency. The LED chips are formed as unit chips before irradiating the laser, thereby increasing the yield and realizing the mass production by preventing cleavage of the crystal structures. Heat discharging efficiency is also increased by roughening the surface of an n-type GaN layer. The light emitting area can be widened 30% more than in the flip-chip technique. Thus, the present invention serves to increase the light output and the heat discharging area, thereby drastically enhancing the performance of manufacturing high-output LEDs.

  • Publication number: 20060124941
    Abstract: Disclosed is a light emitting diode (LED) device that comprises a crystal structure of a sapphire substrate-free gallium nitride (GaN) LED, wherein the crystal structure is mounted on a first surface of a sub-mount substrate in the form of a unit chip, and the first surface of the sub-mount substrate has a surface area greater than the surface area of a region in which the unit chip is bonded. Preforms for manufacturing the LED device and a method for manufacturing the LED device are also disclosed. The sapphire substrate, on which the crystal structure of the light emitting diode has grown, is processed into a unit chip before being removed. Thus, any crack in the crystal structure of the light emitting diode that may occur during the removal of the sapphire substrate can be prevented. Therefore, a thin light emitting diode device can be manufactured in a mass production system.
