Optoelectronic package structure and method of manufacturing the same
An optoelectronic package structure and a method of manufacturing an optoelectronic package structure are provided. The optoelectronic package structure includes a photonic component. The photonic component has an electrical connection region, a blocking region and a region for accommodating a device. The blocking region is located between the electrical connection region and the region for accommodating a device.
1. An optoelectronic package structure, comprising a photonic component, an electronic component, an optical device disposed on a side of the photonic component, and a filling material,
wherein the photonic component comprises a plurality of bonding pads and at least one blocking pad disposed on the side of the photonic component, the photonic component is electrically connected to the electronic component via the plurality of bonding pads, and the at least one blocking pad is disposed outside the plurality of bonding pads,
wherein the blocking pad is located between the optical device and the plurality of bonding pads, and
wherein the filling material is not disposed between the optical device and the at least one blocking pad and the filling material fills between the plurality of bonding pads.
2. The optoelectronic package structure of claim 1 , wherein a width of the least one blocking pad is substantially the same or greater than a width of one of the plurality of bonding pads.
3. The optoelectronic package structure of claim 1 , wherein a length of the least one blocking pad is greater than a length of the plurality of bonding pads.
4. The optoelectronic package structure of claim 1 , wherein the at least one blocking pad comprises metal or alloy, and the plurality of bonding pads and the at least one blocking pad have a same material.
5. The optoelectronic package structure of claim 1 , wherein the filling material reaches a location between the at least one blocking pad and a most adjacent one of the bonding pads.
6. The optoelectronic package structure of claim 1 , wherein an overflow of the filling material is blocked by the at least one blocking pad.
7. The optoelectronic package structure of claim 1 , wherein the plurality of bonding pads are disposed in a first region of the photonic component, and the at least one blocking pad is disposed along at least one edge of the first region.
8. The optoelectronic package structure of claim 7 , wherein the at least one blocking pad is disposed along a first edge of the first region and extends along at least one of other edges of the first region.
9. The optoelectronic package structure of claim 1 , further comprising a waveguide for coupling light with the optical device.
