RENA InEtchSide - automated processing equipment

Single Side Oxide Etching

The RENA InEtchSide automated processing equipment is designed for the single side removal of silicon oxide layers and doped glasses (e.g. PSG or BSG). This can be used in the fabrication of high efficiency cell concepts, e.g. for single side oxide etching using hydrofluoric acid (HF). It is based upon the RENA NIAK inline platform.
