Next, let’s continue to introduce the second equipment system for Dry Etching Process: ICP, which stands for Inductively Coupled Plasma system.
In the ICP system, Radio Frequency (RF) energy is transferred to low-pressure gas through a coil, causing the gas to ionize and form plasma. This plasma is generated under the induction of a radio frequency electromagnetic field, hence the name Inductively Coupled Plasma. This technology provides a high-density plasma, which is crucial for the formation of fine structures in semiconductor manufacturing processes, as it can achieve more precise and uniform etching effects

In next new, we will learn about the CCP system.
