PROBLEM TO BE SOLVED: To reduce the resistivity of a copper wire in an integrated circuit.;SOLUTION: Resistivity of a core wire can be reduced by making smooth the sidewall of a trench and a via. An intermediate level dielectric 102 and an intrametal dielectric 104 are formed sequentially on...
A grain boundary constitutes a significant obstacle along the motion of the electrons. This is because the crystal lattice orientation with respect to the wave vector of the incoming electron is different on both sides of the grain boundary [12], so the electron should unavoidably undergo an ap...
As an example of calculating a volume's resistance, consider the drawing to the left. Assume 12 AWG copper wire with a resistivity (from the table) of1.72x10-6Ω·cm, a cross-sectional area (A) of 0.03309 cm2, and a length of 1 meter. Per the given formula, its resistance is:...
In transition metal compounds, due to the interplay of charge, spin, lattice and orbital degrees of freedom, many intertwined orders exist with close energies. One of the commonly observed states is the so-called nematic electron state, which breaks the
the origin of the linear-Tresistivity behavior and its relationship to the strongly correlated superconductivity remain a mystery. Here we report a universal relationℏdρ/dT=(μ0kB/ℏ)λL2, which bridges the slope of the linear-T-dependent resistivity (dρ/dT) to the London penetration dep...
The following introduces a new method for connecting electric furnace wire: take a section (length 2cm) of thick copper wire (if there is no thick copper wire, twist several strands of thin copper wire instead) or aluminum wire, bend the wires separately and wind them...
