  • Patent number: 11164862
    Abstract: An integrated resistor-capacitor (RC) structure (400) is disclosed. The integrated RC structure includes a vertical capacitor (302,402,306) and a resistive element (308,310) disposed above the capacitor. The integrated RC structure uses a low ohmic substrate (302) to ensure a good ground return path for the capacitor. Further, a resistivity of the substrate is configured such that a top plate (306) of the capacitor provides a reference ground above a predefined frequency. The impedance of the resistive element (308,310) is matched, relative to the reference ground, to a predetermined resistance. As such, the resistance of the resistive element (308,310) can be controlled to provide an impedance controlled RC structure over a range of operating frequencies.

  • Patent number: 11158590
    Abstract: A capacitor interposer layer (CIL) in a die-to-wafer three dimensional integrated circuit (3DIC) and methods of forming the same are disclosed. A CIL is formed in a wafer under a power distribution network (PDN) die area of a chip. Electrical connections between the wafer and the chip are formed using a copper-to-copper bond. This placement allows the capacitor to be close to the PDN die area within the chip to reduce equivalent series resistance (ESR) and equivalent series inductance (ESL), while permitting a relatively low profile device with reduced PDN voltage droop.
