Alternating current vertical light emitting element and manufacturing method thereof
Abstract:
This invention discloses an AC-type vertical light emitting element and fabrication method thereof, which achieves polarity reversal of two LEDs via regional laser stripping and die bonding. The two LEDs are placed on a conductive substrate (e.g. Si substrate); therefore, the bonding pads of the two LEDs are on the back of the conductive substrate and the light emitting surfaces of the two LEDs, thus overcoming such problems of low light emitting efficiency and high thermal resistance of the traditional lateral structure.
