SUMMARY
The sheet resistance of a copper layer in an integrated circuit (IC) can be calculated using the formula R = ρ * (L/A), where ρ is the resistivity. For a copper layer with a thickness of 100 nm and a resistivity of 1.7 μΩ·cm at 27°C, the sheet resistance can be determined by dividing the resistivity by the thickness. This calculation is essential for understanding the electrical properties of interconnecting tracks in ICs.
