  • Patent number: 12211737
    Abstract: In some embodiments, the present disclosure relates to a method that includes forming a dielectric layer over a conductive structure on a substrate. A removal process is performed to remove a portion of the dielectric layer to expose a portion of the conductive structure. The substrate is transported into a cleaning chamber having a wafer chuck below a bell jar structure. A cleaning process is performed to clean the exposed portion of the conductive structure by turning on a noble gas source to introduce a noble gas within the cleaning chamber, turning on an oxygen gas source to introduce oxygen within the cleaning chamber, applying a first bias to a plasma coil to form a plasma gas, and applying a second bias to the wafer chuck. The substrate is removed from the cleaning chamber. A conductive layer is formed over the dielectric layer and coupled to the conductive structure.

  • Patent number: 9960151
    Abstract: A semiconductor device includes a chip, a plurality of first bumps, and a plurality of second bumps. The chip includes an active surface. The first bumps are disposed on the active surface along a first direction. The second bumps are disposed on the active surface along a second direction parallel to the first direction, wherein one of the second bumps is located between adjacent two of the first bumps, a closest distance from the second bumps to the fan-out region is smaller than a closest distance from the first bumps to the fan-out region, and a first width of one of the first bumps is larger than a second width of one of the second bumps.

  • Publication number: 20150325537
    Abstract: An integrated circuit (IC) is provided. The IC includes a chip, a passivation layer, a first metal internal connection, a routing wire and a bonding area. The passivation layer is disposed on the chip, wherein the passivation layer has a first opening. The first metal internal connection is disposed under the passivation layer and disposed in the chip. The routing wire is disposed on the passivation layer, wherein a first end of the routing wire electrically connects to a first end of the first metal internal connection through the first opening of the passivation layer. The bonding area is disposed on the passivation layer, wherein the bonding area electrically connects to a second end of the routing wire.
