High-selectivity etching! Optimization of radical supply by adjusting the spacing between the ICP source and the substrate electrode.
The "SI 500" is an ICP-RIE that controls ion density through ICP power. It achieves a high etch rate with a high plasma density of 10^12 [ions/cm3] using the unique PTSA200ICP source. Additionally, it features low-damage etching through control of ion energy via bias power. 【Features】 ■ Control of ion density through ICP power ■ Control of ion energy through bias power ■ Optimization of radical supply by adjusting the distance between the ICP source and the substrate electrode ■ Low-damage etching ■ High selectivity etching *For more details, please refer to the PDF document or feel free to contact us.
