References As computer processor speeds increase, it is necessary for engineers to increase the number of circuit elements packed into a given area. Individual circuit elements are often connected using very small copper wires" deposited directly onto the surface of the chip. In some processors, these copper Interconnects are about 32 nm wide. What mass of copper (In 9) would be in a 10 mi fength of such an interconnect, assuming a square cross section. The density of copper is 8.96 g/cm
