METHOD FOR USING A MODIFIED POST-ETCH CLEAN RINSING AGENT

摘要

The present invention provides a method for manufacturing an integrated circuit. In one embodiment, the method includes etching one or more openings within a substrate using an etch tool, and subjecting the one or more openings to a post-etch clean, wherein a delay time exists between removing the substrate from the etch tool and the subjecting the one or more opening to the post-etch clean. This method may further include exposing the substrate having been subjected to the post-etch clean to a rinsing agent, wherein a resistivity of the rinsing agent is selected based upon the delay time.
