DRIE Etcher
Overview
Our DRIE(Deep Reactive Ion Etching) Etcher conducts fine cycling & non-cycling etching process of silicon substrate by utilizing high-density plasma. It is applicable for various etching process such as deep trench, isotropic profile with its high-speed etching capability and high aspect ratio.
This machine is stand-alone type(1 chamber) and suitable for mass production line and R&D center that fabricate 4"~ 8" wafer.
Industry Opportunity
- • Increase in DRIE-applicable fabricating & packaging processes in semiconductor industry that were limited to MEMS device
- • DRIE-applicable processes for 3D TSV, 2.5D interposer, PMIC, CIS and other analog devices arose due to 'Micro to Macro' trend in semiconductor industry
- • Expansion of applicable field beyond silicon substrate such as polyimide, Quartz, SiC and so on
Core Competency
