  • Patent number: 10361287
    Abstract: A method of manufacturing a semiconductor device includes receiving a FinFET precursor including a fin structure formed between some isolation regions, and a gate structure formed over a portion of the fin structure; removing a top portion of the fin structure on either side of the gate structure; growing a semiconductive layer on top of a remaining portion of the fin structure such that a plurality of corners is formed over the fin structure; forming a capping layer over the semiconductive layer; performing an annealing process on the FinFET precursor to form a plurality of dislocations proximate to the corners; and removing the capping layer.

  • Patent number: 10096672
    Abstract: A semiconductor device includes a semiconductor substrate having a first conductivity type region including a first conductivity type impurity. A first gate structure is on the semiconductor substrate overlying the first conductivity type region. A second conductivity type region including a second conductivity type impurity is formed in the semiconductor substrate. A barrier layer is located between the first conductivity type region and the second conductivity type region. The barrier layer prevents diffusion of the second conductivity type impurity from the second conductivity type region into the first conductivity type region.

  • Patent number: 9768132
    Abstract: A semiconductor structure includes a substrate, a bond pad over the substrate, and a passivation layer over the substrate and a peripheral region of the bond pad. The bond pad has a bonding region and the peripheral region surrounding the bonding region. The passivation layer has an opening defined therein, and the opening exposes the bonding region of the bond pad. A first vertical distance between an upper surface of the passivation layer and a surface of the bonding region ranges from 30% to 40% of a second vertical distance between a lower surface of the passivation layer and an upper surface of the peripheral region.

  • Patent number: 9490345
    Abstract: A semiconductor device includes a gate structure on a substrate; a raised source/drain region adjacent to the gate structure; and an interconnect plug on the doped region. The raised source/drain region includes a top surface being elevated from a surface of the substrate; and a doped region exposed on the top surface. The doped region includes a dopant concentration greater than any other portions of the raised source/drain region. A bottommost portion of the interconnect plug includes a width approximate to a width of the doped region.
