The Si/ | The Si/Al<sub>2</sub>O<sub>3</sub>/BARC/DUV stack was first processed in Pegasus 2 to etch the BARC layer, and the alumina was etched in the III-V ICP, using a BCl<sub>3</sub>/Ar recipe. With pillars and holes, the BARC was etched for 12 min on Pegasus 2, followed by 90 minutes on the III-V ICP. The nanoholes had two different approaches, starting with 260 minutes on the III-V ICP. However, it was seen that after the III-V ICP process, the leftover resist on the sample was removed during the CORE process on Pegasus 2. | ||
