发明名称 Electrochemical Plating
摘要 Methods for use in electrochemical plating processes are described herein. An exemplary method includes determining a wafer electrical property associated with a wafer, wherein the wafer electrical property affects the wafer during an electrochemical plating (ECP) process; adjusting a process parameter to be applied to the wafer during the ECP process based on the determined wafer electrical property, wherein the process parameter specifies at least one of a current or a voltage; and applying the adjusted process parameter to the wafer undergoing the ECP process. In some implementations, the process parameter is adjusted, such that a peak entry current of the ECP process substantially matches a plating current of the ECP process induced following the peak entry current.
