Abstract: Apparatuses for supplying power supply voltage in a plurality of dies are described. An example apparatus includes: a circuit board; a regulator on the circuit board that regulates a first voltage; a semiconductor device on the circuit board that receives the first voltage through a power line in the circuit board. The semiconductor device includes: a substrate on the circuit board, stacked via conductive balls, that receives the first voltage from the power line via the conductive balls; a plurality of dies on the semiconductor device, stacked via bumps, each die including a first conductive via that receives the first voltage via the bumps; a plurality of pillars between adjacent dies and couple the first conductive vias of the adjacent dies; and a sense node switch circuit that selectively couples one first conductive via of one die among the plurality of dies to the regulator.

Abstract: In one embodiment, an electrically conductive trench in an integrated circuit allows for the formation of capacitors between the trench and other portions of the integrated circuit. For example, a capacitor may be formed between the trench and an electrically conductive line. Among other advantages, the capacitor provides a relatively large capacitance while occupying a relatively small area.

Abstract: In one embodiment, a passivation level includes a low-k dielectric. The low-k dielectric helps lower the capacitance of a metal line in a last metal level, which may be just below the passivation level. In another embodiment, the metal line is relatively thick. This helps lower the metal line's resistance and resulting RC delay.
