High-throughput low temperature tungsten deposition process for 0.25 /spl mu/m technology

A new high-throughput, low temperature tungsten deposition process is presented. Excellent step coverage is obtained because of the low temperature and high pressure. No plug seams are observed. Therefore, this process is particularly suitable for post W-CMP processing, as plug seam attack will be m...

Abstract A new high-throughput, low temperature tungsten deposition process is presented. Excellent step coverage is obtained because of the low temperature and high pressure. No plug seams are observed. Therefore, this process is particularly suitable for post W-CMP processing, as plug seam attack will be minimal. Electrical measurements have demonstrated that this new process has the same process capability in terms of electrical performance and yield.
