  • Patent number: 11961770
    Abstract: Some embodiments of the present disclosure relate to a processing tool. The tool includes a housing enclosing a processing chamber, and an input/output port configured to pass a wafer through the housing into and out of the processing chamber. A back-side macro-inspection system is arranged within the processing chamber and is configured to image a back side of the wafer. A front-side macro-inspection system is arranged within the processing chamber and is configured to image a front side of the wafer according to a first image resolution. A front-side micro-inspection system is arranged within the processing chamber and is configured to image the front side of the wafer according to a second image resolution which is higher than the first image resolution.

  • Publication number: 20240087877
    Abstract: A backside metallized compound semiconductor device includes a compound semiconductor wafer and a metal layered structure. The compound semiconductor wafer includes a substrate having opposite front and back surfaces, and a ground pad structure formed on the front surface. The substrate is formed with a via extending from the back surface to the front surface to expose a side wall of the substrate and a portion of the ground pad structure. The metal layered structure is disposed on the back surface, and covers the side wall and the portion of the ground pad structure. The metal layered structure includes an adhesion layer, a seed layer, a gold layer, and an electroplated copper layer that are formed on the back surface in such order. The method for manufacturing the backside metallized compound semiconductor device is also disclosed.

  • Publication number: 20240079301
    Abstract: An electronic package is provided, in which a mesh structure is disposed between a circuit structure and an electronic element to increase the shunt path of current. Therefore, when the electronic element is used as an electrode pad of a power contact, the current can be passed through a conductive sheet of the circuit structure via the mesh structure, such that the power loss can be reduced and the IR drop of the electronic element can meet the requirements.

  • Publication number: 20230405643
    Abstract: An embodiment system, configured to clean a semiconductor package assembly, may include a sprayer device including a plurality of nozzles configured to direct a pressurized cleaning fluid toward the semiconductor package assembly; a conveyor configured to move the semiconductor package assembly relative to the sprayer device along a first direction; and a dryer spatially displaced from the sprayer device and configured to direct a pressurized gas flow toward the semiconductor package assembly to remove cleaning fluid introduced by the sprayer device. Each of the plurality of nozzles may be displaced from one another along a second direction to thereby generate respective separate spray distribution patterns. Adjacent nozzles may be further displaced from one another along a third direction to thereby a reduce an overlap of adjacent spray distribution patterns relative to a configuration in which the adjacent nozzles are not displaced from one another along the third direction.
