Claim:
1. A light emitting diode (LED) flip chip structure comprising: semiconductor layers, including a first conductivity layer, an active layer, and a second conductivity layer, the semiconductor layers having a bottom surface for facing a bonding surface and a top surface through which light is emitted; a first electrode opposing the bottom surface and electrically connected to the first conductivity layer; a second electrode opposing the bottom surface and electrically connected to the second conductivity layer; a first dielectric layer insulating a sidewall of the first electrode and an opposing sidewall of the second electrode, wherein there is at least one gap between the first dielectric layer on the sidewall of the first electrode and the first dielectric layer on the opposing sidewall of the second electrode; and a first metal layer, formed separately from the first electrode and the second electrode, a first portion of the first metal layer at least partially filling the at least one gap and electrically insulated from the second electrode, wherein the first metal layer forms a bonding metal on the bottom surface for bonding to the bonding surface to conduct current to the first conductivity layer via the first electrode.
