Molded package structure with glue bleed stopper for sealing a MEMs device method of packaging a MEMs device |
摘要 |
A semiconductor package includes an electrically conductive lead-frame, including a first die paddle having a first opening, and a plurality of electrically conductive leads, a ridge formed around a perimeter of the first opening, and an electrically insulating molding compound. The electrically insulating molding compound includes an interior cavity being defined by a planar base surface and outer sidewalls, a second opening formed in the base surface, and an interior sidewall within the interior cavity. The molding compound is formed around the lead-frame with the first die paddle in the interior cavity. The first and second openings are aligned with one another so as to form a port that provides access to the interior cavity. The ridge and the interior sidewall form a dam that is configured to collect liquefied sealant and prevent the liquefied sealant from overflowing into the port or into adjacent regions of the interior cavity. |

1. A semiconductor package, comprising:
an electrically conductive lead-frame, comprising a first die paddle having a first opening, and a plurality of electrically conductive leads; a ridge formed around a perimeter of the first opening; and an electrically insulating molding compound, comprising an interior cavity being defined by a planar base surface and outer sidewalls of the molding compound, a second opening formed in the base surface, and an interior sidewall being arranged within the interior cavity; wherein the molding compound is formed around the lead-frame with the first die paddle arranged in the interior cavity, wherein the first and the second openings are aligned with one another so as to form a port that provides access to the interior cavity, and wherein the ridge and the interior sidewall collectively form a dam that is configured to collect liquefied sealant and prevent the liquefied sealant from overflowing into the port or into adjacent regions of the interior cavity. |
