Abstract
A LED structure includes a substrate, a bonding layer, a first doping type semiconductor layer, a multiple quantum well (MQW) layer, a second doping type semiconductor layer, a passivation layer and an electrode layer. The bonding layer is formed on the substrate, and the first doping type semiconductor layer is formed on the bonding layer. The MQW layer is formed on the first doping type semiconductor layer, and the second doping type semiconductor layer is formed on the MQW layer. The second doping type semiconductor layer includes an isolation material made through implantation, and the passivation layer is formed on the second doping type semiconductor layer. The electrode layer is formed on the passivation layer in contact with a portion of the second doping type semiconductor layer through a first opening on the passivation layer.
