These two ETCHing technologies have different application scenarios and advantages in RuneAlpha. Wet ETCH is primarily used for etching metals, oxides, and semiconductor materials, featuring a  simple operation and low cost. On the other hand, dry ETCH is aimed at high-precision and high-purity material etching, boasting a high etching rate and minimal side effects. These two ETCHing techniques complement each other in RuneAlpha, providing users with more diverse options."}]}],"pr":"b3f9968923561ed466d657624e90d5fe2aadd771834c931faa4bde80524b2edf"}
