摘要:
A chemically mechanically polishing method is provided, which includes slide-contacting a polishing film with a polishing pad while feeding a first chemical liquid and a second chemical liquid to the polishing pad. The first chemical liquid contains an electrolyte and bubbles having a diameter ranging from 10 nm to 1000 μm, and the second chemical liquid contains abrasive particles.
