  • Publication number: 20200402954
    Abstract: The present disclosure relates to a method of forming a semiconductor device structure. The method may be performed by forming a gate structure along a first side of a semiconductor substrate. The semiconductor substrate is thinned. Thinning the semiconductor substrate causes defects to form along a second side of the semiconductor substrate opposing the first side of the semiconductor substrate. Dopants are implanted into the second side of the semiconductor substrate after thinning the semiconductor substrate. The semiconductor substrate is annealed to form a doped layer after implanting the dopants. The doped layer is formed along the second side of the semiconductor substrate.

  • Patent number: 10833119
    Abstract: The present disclosure relates to an integrated circuit having a bond pad with a relatively flat surface topography that mitigates damage to underlying layers. In some embodiments, the integrated circuit has a plurality of metal interconnect layers within a dielectric structure over a substrate. A passivation structure is arranged over the dielectric structure. The passivation structure has a recess with sidewalls connecting a horizontal surface of the passivation structure to an upper surface of the passivation structure. A bond pad is arranged within the recess and has a lower surface overlying the horizontal surface. One or more protrusions extend outward from the lower surface through openings in the passivation structure to contact one of the metal interconnect layers. Arranging the bond pad within the recess and over the passivation structure mitigates stress to underlying layers during bonding without negatively impacting an efficiency of an image sensing element within the substrate.
