Laying out two metal wires directly next to each other, and with minimum spacing, for a long distance increases the capacitance between the two conductors, C_m. If the two conductors are VDD and ground, is this a good idea? Why or why not?

Propose, and lay out, a test structure to measure the sheet resistance of metal3. Comment on the trade-offs between accuracy and layout size. Using your test structure provide a numerical example of calculating sheet resistance for metal3.
