Copper interconnects are used in integrated circuits to reduce propagation delays and power consumption. Since copper is a better conductor than aluminium , ICs using copper for their interconnects can have interconnects with narrower dimensions, and use less energy to pass electricity through them.
In integrated circuits (ICs), interconnects are structures that connect two or more circuit elements (such as transistors) together electrically. The design and layout of interconnects on an IC is vital to its proper function, performance, power efficiency, reliability, and fabrication yield. The material interconnects are made from depends on ...
An electrical wiring interconnect system (EWIS) is the wiring system and components (such as bundle clamps, wire splices, etc.) for a complex system. The term originated in the aviation industry but was originally designated as Electrical Interconnection Systems (EIS). [ 1 ]
A via (Latin, 'path' or 'way') is an electrical connection between two or more metal layers of a printed circuit boards (PCB) or integrated circuit. Essentially a via is a small drilled hole that goes through two or more adjacent layers; the hole is plated with metal (often copper) that forms an electrical connection through the insulating layers.
A split-50 M-type 66 block with bridging clips attached. A 66 block is a type of punch-down block used to connect sets of wires in a telephone system. They have been manufactured in four common configurations, A, B, E and M. [a] A and B styles have the clip rows on 0.25" centers while E and M have the clip rows on 0.20" centers.
There are several methods for 3D IC design, including recrystallization and wafer bonding methods. There are two major types of wafer bonding, Cu-Cu connections (copper-to-copper connections between stacked ICs, used in TSVs) [18] [19] and through-silicon via (TSV). 3D ICs with TSVs may use solder microbumps, small solder balls as an interface between two individual dies in a 3D IC.

The BEOL process deposits metalization layers on the silicion to interconnect the individual devices generated during FEOL (bottom). CMOS fabrication process. Back end of the line or back end of line (BEOL) is a process in semiconductor device fabrication that consists of depositing metal interconnect layers onto a wafer already patterned with devices.
A thermal copper pillar bump, also known as a "thermal bump", is a thermoelectric device made from thin-film thermoelectric material embedded in flip chip interconnects (in particular copper pillar solder bumps) for use in electronics and optoelectronic packaging, including: flip chip packaging of CPU and GPU integrated circuits (chips), laser diodes, and semiconductor optical amplifiers (SOA).
