    Abstract: A three-dimensional integrated circuit having a dual or multiple power domain is capable of less energy consumption operation under a given clock rate, which results in an enhanced power-performance-area (PPA) envelope. Sequential logic operates under a system clock that determines the system throughput, whereas combinational logic operates in a different power domain to control overall system power including dynamic and static power. The sequential logic and clock network may be implemented in one tier of the three-dimensional integrated circuit supplied with a relatively high power supply voltage, whereas the combinational logic may be implemented in another tier of the three-dimensional integrated circuit supplied with a relatively low power supply voltage. Further pipeline reorganization may be implemented to leverage the system energy consumption and performance to an optimal point.

    Abstract: A three-dimensional (3-D) integrated circuit (3DIC) with a graphene shield is disclosed. In certain embodiments, at least a graphene layer is positioned between two adjacent tiers of the 3DIC. A graphene layer is a sheet like layer made of pure carbon, at least one atom thick with atoms arranged in a regular hexagonal pattern. A graphene layer may be disposed between any number of adjacent tiers in the 3DIC. In exemplary embodiments, the graphene layer provides an electromagnetic interference shield between adjacent tiers or layers in the 3DIC to reduce crosstalk between the tiers. In other exemplary embodiments, the graphene layer(s) can be disposed in the 3DIC to provide a heat sink that directs and dissipates heat to peripheral areas of the 3DIC. In some embodiments, the graphene layer(s) are configured to provide both EMI shielding and heat shielding.

    Abstract: Multi-level conversion flip-flop circuits for multi-power domain integrated circuits (ICs) and related methods are disclosed. A flip-flop circuit latches a representation of a received input data signal in a lower voltage domain, in a latch circuit in a higher voltage domain without need for separate voltage level shifters. As a result, insertion loss/delay is minimized, thereby increasing performance. In certain aspects, the flip-flop circuits employ a gate-controlled, data control transistor to control activation of the latch circuit. By coupling the input data signal to a gate of the data control transistor, the input data signal in the lower voltage domain is not directly latched into the latch circuit. Instead, the data control transistor is configured to activate the latch circuit to latch a voltage in the higher voltage domain representing a logic value of the input data signal in the lower voltage domain in response to a clock signal.

    Abstract: A three-dimensional integrated circuit comprising top tier nanowire transistors formed on a bottom tier of CMOS transistors, with inter-tier vias, intra-tier vias, and metal layers to connect together the various CMOS transistors and nanowire transistors. The top tier first begins as lightly doped regions on a first wafer, with an oxide layer formed over the regions. Hydrogen ion implantation forms a cleavage interface. The first wafer is flipped and oxide bonded to a second wafer having CMOS devices, and the cleavage interface is thermally activated so that a portion of the lightly doped regions remains bonded to the bottom tier. Nanowire transistors are formed in the top tier layer. The sources and drains for the top tier nanowire transistors are formed by in-situ doping during epitaxial growth. After oxide bonding, the remaining process steps are performed at low temperatures so as not to damage the metal interconnects.

    Abstract: A three-dimensional (3D) memory cell separation among 3D integrated circuit (IC) (3DIC) tiers is disclosed. Related 3DICs, 3DIC processor cores, and methods are also disclosed. In embodiments disclosed herein, memory read access ports of a memory block are separated from a memory cell in different tiers of a 3DIC. 3DICs achieve higher device packing density, lower interconnect delays, and lower costs. In this manner, different supply voltages can be provided for the read access ports and the memory cell to be able to lower supply voltage for the read access ports. Static noise margins and read/write noise margins in the memory cell may be provided as a result. Providing multiple power supply rails inside a non-separated memory block that increases area can also be avoided.
