A metal line L 20 pm W 025 mu m has a sheet resistance 5 O

A metal line (L = 20 pm, W = 0.25 mu m) has a sheet resistance 5 Ohm/sq. Calculate the resistance of the metal line. A dielectric material is placed between two parallel lines. The length L = 1 cm, width W = 0.28 mu m, thickness T = 0.3 mu m, and spacing S = 0.36 mu m. Calculate the RC time delay. The metal is Al with a resistivity of 2.67 mu ohm-cm and the dielectric is oxide with dielectric constant 3.9. Calculate the RC time delay. The metal is Cu with a resistivity of 1.7 mu ohm-cm and the dielectric is organic polymer with dielectric constant 2.8. Compare the results in (a) and (b). How much can we decrease the RC time delay?

Solution

An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow
