Claim Text:
1. A flip chip type laser diode, comprising: a first substrate; a first semiconductor layer, disposed on the first substrate; an emitting layer, disposed on a part of the first semiconductor layer; a second semiconductor layer, disposed on the emitting layer and forming a ridge mesa; at least one current conducting layer, disposed on a part of the first semiconductor layer, wherein the at least one current conducting layer is electrically connected with the first semiconductor layer and isolated from the second semiconductor layer; a patterned insulating layer, covering the first semiconductor layer, the emitting layer, the second semiconductor layer, and the at least one current conducting layer and comprising a first zone and a second zone, wherein the first zone exposes a part of the at least one current conducting layer, and the second zone exposes a part of the second semiconductor layer; a first electrode, disposed in the first zone of the patterned insulating layer; and a second electrode, disposed in the second zone of the patterned insulating layer, wherein a projection of the ridge mesa projected to the first substrate respectively covers a part of a projection of the first electrode and a part of a projection of the second electrode projected to the first substrate, wherein polarity of the first electrode and polarity of the second electrode are reversed, and the first electrode and the second electrode are disposed at the same side of the first substrate.
