Abstract: The present disclosure proposes a packaging structure for a metallic bonding based opto-electronic device and a manufacturing method thereof. According to the embodiments, the packaging structure for an opto-electronic device may comprise an opto-electronic chip and a packaging base. The opto-electronic chip comprises: a substrate having a first substrate surface and a second substrate surface opposite to each other; an opto-electronic device formed on the substrate; and electrodes for the opto-electronic device which are formed on the first substrate surface. The packaging base has a first base surface and a second base surface opposite to each other, and comprises conductive channels extending from the first base surface to the second base surface.
