Abstract
A silicon wafer storage box must be secured by a functional and convenient latch during the fabrication and transportation of silicon wafers. The present invention encompasses such a functional, convenient latch adaptable for either manual or automated manipulation. The invention includes a rigid upper tab having a peg adapted for interaction with a robot arm of an automated process. The invention also includes a resiliently flexible bottom bight having a horizontally extending rigid lower tab, adapted for manual manipulation. The invention permits convenient, efficient manipulation of the latch by either a person or by an automated process.
