发明名称 METHOD FOR DEEP AND VERTICAL DRY ETCHING OF DIELECTRICS
摘要 <p>A method of etching a dielectric, such as SiO2, to produce vertical sidewalls is disclosed wherein the process is carried out at a high etch rate, using low energy ion bombardment, using C4F8 as a main etchant gas. The SiO2 sidewall profiles are controlled by varying the temperature of the temperature of the sample.</p>
