Abstract
A light-emitting diode at least comprising: a substrate formed on a first electrode; a first bonding layer having a first conductivity formed on the substrate; an active layer formed on the first bonding layer; a second bonding layer having a second conductivity formed on the active layer; a window layer having the second conductivity formed on the second bonding layer, the resistance of the window layer being smaller than the resistance of the second bonding layer; a contact layer having the second conductivity formed on the window layer for providing an ohmic contact, the contact layer having a recessed region extending from the top portion of the contact layer to the bottom portion of the contact layer thereby going through the surface of the window layer; a conductive transparent oxide layer formed on the contact layer and filling up the recessed region in the contact layer, the resistance of the conductive transparent oxide layer being smaller than the resistance of the window layer and the contact layer; and a second electrode formed on the surface of a portion of the conductive transparent oxide layer, the second electrode being approximately in alignment with the recessed region in the contact layer.
