Question

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?

Explanation / Answer

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
