Summary:This invention is a method of fabricating an integrated-circuit device by utilizing a multilevel structure that includes a planerizing layer (e.g.22). Reactive ion etching of the planarizing layer of a multilevel resist structure utilized to make integrated-circuit devices is carried out employing a plasma derived from carbon dioxide. The etching step is characterized by high throughput, good linewidth control, negligible radiation damage and low sensitivity to process parameter variations.
