Classification: CPC H | IPC H

Claim 14:
15. A semiconductor package comprising:
a package substrate comprising:
an insulating layer comprising a first upper insulating layer having a mounting surface, and a second upper insulating layer provided on the first upper insulating layer;
a wiring pattern extending in the insulating layer; and
a chip bonding pad provided on the mounting surface of the first upper insulating layer and connected to the wiring pattern, the chip bonding pad having a tapered shape in which a horizontal cross-sectional area of the chip bonding pad decreases away from the mounting surface of the first upper insulating layer in a vertical direction; and

a semiconductor chip mounted on the package substrate, the semiconductor chip comprising:
a semiconductor substrate having a top surface and a bottom surface, and comprising an active layer adjacent to the bottom surface;
a chip pad provided on the bottom surface of the semiconductor substrate and connected to the active layer; and
a chip connection terminal connecting the chip pad to the chip bonding pad of the package substrate,

wherein a vertical cross-section of the chip bonding pad has a trapezoidal shape,
wherein a top side of the vertical cross-section of the chip bonding pad has a horizontal length of about 5 μm to about 25 μm,
wherein a bottom side of the vertical cross-section of the chip bonding pad has a horizontal length that is about 1.1 times to about 6 times the horizontal length of the top side,
wherein lateral sides of the vertical cross-section of the chip bonding pad connect the top side to the bottom side,
wherein the chip connection terminal surrounds the top side and the lateral sides of the chip bonding pad, and
wherein the second upper insulating layer comprises a hole in which the chip bonding pad is provided and through which the chip bonding pad and a portion of the mounting surface of the first upper insulating layer are exposed.
