RIE(reactive ion etcher)

Model RIE-10NR
Manufacturer (Country) SAMCO (Jap)
Purchase Date 2019-04-05
Purpose of Use A device used in nanoscale processes with the following functions and characteristics: Selective dry etching by generating a chemically reactive plasma by applying RF frequency electromagnetic field; Capable of anisotropic etching, unlike wet etching processes which are mostly isotropic etching; Suitable for fabricating nanoscale devices overcoming the limit associated with etching bias; Free from damage likely to occur during the drying process after being taken from reagents; Mainly used for etching Si-based material layers; Applicable to a wide range of material types such as semiconductor materials, carbon-based materials such as graphene, dielectric materials, and organic materials.
