Bare wafer stockers with integrated sorting and metrology for fab inventory management — NADAtech automation

Automated Stockers for Bare Wafer Handling

Smart Storage for Production-Ready Workflows

NADAtech Wafer Stockers provide automated, space-efficient storage and transfer solutions for bare wafers in cleanroom environments. Designed to replace traditional wire racks and reduce manual handling, these systems increase throughput, improve yield, and streamline flow management. With integrated sorting, OCR, and environmental controls like N₂ purging, ionization, and optional temperature/humidity regulation, stockers help prevent contamination and ensure wafer traceability. NADAtech also supports just-in-time WIP delivery and integration with automated material handling systems (AMHS), making these inline process buffers a critical component of modern fab efficiency.
