Problem 2: (Points: 2x6 = 12)
In an integrated circuit, a rectangular piece of aluminum is used as interconnect. The resistivity of
aluminum is $$\rho = 2.7 \times 10^{-8} \Omega m$$. The sheet resistance is found as $$R_â–¡ = 0.1 \Omega/â–¡$$. It is measured that $$\frac{L}{W} = 100$$.
(a) Calculate the thickness H of the sample.
(b) Calculate the total resistance of the sample.
