We investigated a wafer level Cu/low-k thickness measurement technique and compared it to the electrical and surface profiling techniques. With this optical technique, we can achieve a comprehensive within-die and within-wafer Cu/low-k thickness monitoring which allows for a more accurate Cu CMP process control in advance Cu/low-k damascene structures. |
