A dielectric material is placed between two parallel lines T

A dielectric material is placed between two parallel lines. The length L = 1 cm, width W = 0.28 mum, thickness T = 0.3 mum, and spacing S = 0.36 mum. 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?
