Method and apparatus for storing and transporting semiconductor wafers in a vacuum pod

摘要

Methodology and system for using vacuum pods to store/transport semiconductor wafers to efficiently reduce contamination of the wafers while reducing cost, cycle time, and process steps and tools without the need for a complete reconfiguration of processes/tools in the fabrication facility are disclosed. Embodiments include configuring a wafer pod with an isolated vacuum environment for storing and transporting semiconductor wafers; configuring a load port module with an isolated vacuum environment to interface with the wafer pod; transporting the wafer pod, including semiconductor wafers, to interlock with the load port module; creating a merged vacuum environment including the isolated vacuum environments of the wafer pod and the load port module; increasing a pressure level in the merged vacuum environment for creating a merged ambient atmospheric environment; and transferring the semiconductor wafers through a transfer chamber, with an isolated environment, from the load port module to a semiconductor wafer processing device.
