Previum preclean module

Overview

The Previum preclean module is a wafer surface preparation module designed for use with ASM's Previum epitaxy platform to condition wafer surfaces prior to epitaxial deposition. It performs controlled pre-growth cleaning to remove surface contaminants and native oxides, yielding a reproducible surface state for subsequent epitaxial nucleation and layer growth. The module is engineered for integration into automated epitaxy toollines used in industrial semiconductor manufacturing and R&D labs, providing recipe-driven process control and cycle-to-cycle repeatability to support consistent layer quality and yield. Its design emphasizes low particle generation and contamination control so it can be operated in cleanroom production environments and aligned with throughput and automation sequencing of adjacent epitaxy modules. Install the Previum preclean module immediately upstream of epitaxial reactors to prepare wafers for deposition, reducing defectivity and improving nucleation uniformity and film quality. It is suited to semiconductor fabrication and process development contexts where tight control of surface chemistry and contamination is required before epitaxy. The module is operated as part of integrated tool clusters or an epitaxy line to streamline automated wafer transfer, recipe management and yield-sensitive production workflows.
