    摘要: A wafer-level chip-size package includes a semiconductor structure. A bonding pad is formed over the semiconductor structure, including a plurality of conductive segments. A conductive component is formed over the semiconductor structure, being adjacent to the bonding pad. A passivation layer is formed, exposing a portions of the conductive segments of the first bonding pad. A conductive redistribution layer is formed over the portions of the conductive segments of the first bonding pad exposed by the passivation layer. A planarization layer is formed over the passivation layer and the conductive redistribution layer, exposing a portion of the conductive redistribution layer. A UBM layer is formed over the planarization layer and the portion of the conductive redistribution layer exposed by the planarization layer. A conductive bump is formed over the UBM layer.

    摘要: A MOS transistor structure is provided. The MOS transistor structure includes a semiconductor substrate having an active area including a first edge and a second edge opposite thereto. A gate layer is disposed on the active area of the semiconductor substrate and has a first edge extending across the first and second edges of the active area. A source region having a first conductivity type is in the active area at a side of the first edge of the gate layer and between the first and second edges of the active area. First and second heavily doped regions of a second conductivity type are in the active area adjacent to the first and second edges thereof, respectively, and spaced apart from each other by the source region.
