Product Specifications

Technical details and manufacturing context for Load Port

Definition
A load port is a critical interface component in semiconductor wafer fabrication systems that provides automated, controlled access for wafer cassettes (FOUPs, SMIF pods) to be loaded into and unloaded from processing equipment. It serves as the entry/exit point where cassettes are transferred between the factory automation system and individual process tools, maintaining the clean environment required for semiconductor manufacturing.
Working Principle
The load port typically consists of a docking mechanism that aligns and secures the wafer cassette, a door opener that interfaces with the cassette's environmental seal, and sensors that verify proper positioning. When a cassette is presented, the load port verifies its identity, opens the cassette door, and transfers wafers to the equipment's internal handling system while maintaining nitrogen purge or vacuum conditions to prevent contamination.
