Professor N Cheung, U.C. Berkeley EE F Lecture 15 1 Reactive Ion Etching (R IE) ~ plasma wafers RF MHz Parallel-Plate Reactor Plasma generates (1) Ions. Reactive Ion Etching is a simple operation, and an economical solution for general plasma etching. Some manufacturers introduce a quartz, graphite or Silicon Carbide plates to avoid sputtering and re-deposition of the lower electrode material. These plates are typically called a "cover-plate” or tray. Plasma Based Dry Etching • RF power is used to drive chemical reactions • Plasma takes place of elevated temperatures or very reactive chemicals •Types: – Physical etching – Chemical etching – Reactive ion etching (RIE) – Deep reactive ion etching (DRIE) Plasma •Plasma= partially ionized gas consisting of equal. Ttfftil thiTemperature effects in plasma etching. ¾Wafer surface temp. depends on: Chuck temperature - I’ dd itIon’s energy and density ¾Reaction probability of radicals depends on substrate temperature. Wet Etching - substrates are immersed in a reactive solution (etchant). The layer to be etched is removed by chemical reaction or by dissolution. The reaction products must be soluble and are carried away by the etchant solution. Dry Etching - Substrates are immersed in a reactive gas (plasma). pdf.
