Abstract—Wet chemical processes in integrated circuit (IC) manufacturing are used in many applications, e.g., post-etch residue removal and pre-deposition surface treatment. While advanced single-wafer wet spin tools are part of the critical toolset for advanced IC fabrication, non-optimized tool hardware and/or process may induce different types of wafer surface charging issues. In this pap…
Abstract—Etching of SiO2 films using aqueous HF-based chemistries is widely used in integrated circuit and microelectromechanical device industries. To precisely control film loss during cleaning or etching processes, good control over the contact time between the wet chemistry and the substrate is necessary. An integrated wet etch and dry reactor system has been designed and fabricated by s…
