Abstract: A bonding structure that may be used to form 3D-IC devices is formed using first oblong bonding pads on a first substrate and second oblong bonding pads one a second substrate. The first and second oblong bonding pads are laid crosswise, and the bond is formed. Viewed in a first cross-section, the first bonding pad is wider than the second bonding pad. Viewed in a second cross-section at a right angle to the first, the second bonding pad is wider than the first bonding pad. Making the bonding pads oblong and angling them relative to one another reduces variations in bonding area due to shifts in alignment between the first substrate and the second substrate. The oblong shape in a suitable orientation may also be used to reduce capacitive coupling between one of the bonding pads and nearby wires.

Abstract: The present disclosure provides a semiconductor structure. The semiconductor structure includes device fins formed on a substrate; fill fins formed on the substrate and disposed among the device fins; and gate stacks formed on the device fins and the fill fins.

The first and second dielectric material layers are different from each other in composition.

Abstract: Some embodiments of the present disclosure relate to an integrated chip including an extended via that spans a combined height of a wire and a via and that has a smaller footprint than the wire. The extended via may replace a wire and an adjoining via at locations where the sizing and the spacing of the wire are reaching lower limits. Because the extended via has a smaller footprint than the wire, replacing the wire and the adjoining via with the extended via relaxes spacing and allows the size of the pixel to be further reduced. The extended via finds application for capacitor arrays used for pixel circuits.
