摘要:
a central reference clock is placed in a substantially middle chip of a 3-D chip-stack. The central reference clock is distributed to each child chip of the 3-D chip-stack, so that a plurality of clocks is generated for each individual chip in the 3-D-stack in a synchronous manner. A predetermined number of through-silicon-vias and on-chip wires are employed to form a delay element for each slave clock, ensuring that the clock generated for each child chip is substantially synchronized. Optionally, an on-chip clock trimming circuit is embedded for further precision tuning to eliminate local clock skews.

Programmable fuse-type through silicon vias (TSVs) in silicon chips are provided with non-programmable TSVs in the same chip. The programmable fuse-type TSVs may employ a region within the TSV structure having sidewall spacers that restrict the cross-sectional conductive path of the TSV adjacent a chip surface contact pad. Application of sufficient current by programming circuitry causes electromigration of metal to create a void in the contact pad and, thus, an open circuit. Programming may be carried out by complementary circuitry on two adjacent chips in a multi-story chip stack.

An apparatus is provided for implementing an enhanced hand shake protocol for microelectronic communication systems. A transmitter and a receiver is coupled together by a transmission link. The transmitter receives an idle input. The idle input is activated when the transmitter is not transmitting data and the transmitter applies a first common 10 mode level to the receiving unit. The idle input is deactivated when the transmitter is ready to transmit data and the transmitter raises the common mode level to the receiving unit. Responsive to the receiver detecting the common mode level up-movement, then the receiver receives the transmitted data signals. After the desired data has been sent, the 15 transmitter terminates communications, drops the common mode level with the idle input being activated.
摘要:
A design structure for an impedance matcher that automatically matches impedance between a driver and a receiver. The design structure for an impedance matcher includes a phase-locked loop (PLL) circuit that locks onto a data signal provided by the driver. The impedance matcher also includes tunable impedance matching circuitry responsive to one or more voltage-controlled oscillator control signals within the PLL circuit so as to generate an output signal that is impedance matched with the receiver.
摘要:
Design structure embodied in a machine readable medium for designing, manufacturing, or testing a design. The design structure includes an interconnect structure with a liner formed on roughened dielectric material in an insulating layer and a conformal liner repair layer bridging that breaches in the liner. The conformal liner repair layer is formed of a conductive material, such as a cobalt-containing material. The conformal liner repair layer may be particularly useful for repairing discontinuities in a conductive liner disposed on roughened dielectric material bordering the trenches and vias of damascene interconnect structures.

Embodiments of the invention generally relate to methods, systems and design structures for semiconductor devices and more specifically to forming partially silicided and fully silicided structures. Fabricating the partially silicided and fully silicided structures may involve creating one or more gate stacks. A polysilicon layer of a first gate stack may be exposed and a first metal layer may be deposited thereon to create a partially silicided structure. Thereafter, a polysilicon layer of a second gate stack may be exposed and a second metal layer may be deposited thereon to form a fully silicided structure. In some embodiments, the polysilicon layers of one or more gate stacks may not be exposed, and resistors may be formed with the unsilicided polysilicon layers.

Embodiments of the invention generally relate to methods, systems and design structures for semiconductor devices, and more specifically to interconnecting semiconductor devices. A silicide layer may be formed on selective areas of a fin structure connecting one or more semiconductor devices or semiconductor device components. By providing silicided fin structures to locally interconnect semiconductor devices, the use of metal contacts and metal layers may be obviated, thereby allowing formation of smaller, less complex circuits.

摘要:
Design structure embodied in a machine readable medium for designing, manufacturing, or testing a design. The design structure comprises an insulating layer of a dielectric material, an opening having sidewalls extending from a top surface of the insulating layer toward a bottom surface of the insulating layer, and a conductive feature disposed in the opening. The design structure includes a top capping layer disposed on at least a top surface of the conductive feature and a conductive liner layer disposed between the insulating layer and the conductive feature along at least the sidewalls of the opening. The conductive liner layer of the design structure has sidewall portions that project above the top surface of the insulating layer adjacent to the sidewalls of the opening.
