The purpose of this Specification is to establish basic physical dimensions for the Panel FOUP intended to be used to transport and store panels, as specified by SEMI 3D20 for 510 mm × 515 mm panel size and 600 mm × 600 mm panel size.
 

This Specification is intended to define the reference planes for the dimensions of the Panel FOUP and the panel load port.
 

This Specification is intended to define a set of requirements to ensure interoperability of load ports and Panel FOUP without limiting innovative solutions.

This Standard specifies the external features and dimensions of the Panel FOUP, however, individual dimensions related to panel size and number of stored panels are specified by the Subordinate Standards.
 

This Standard specifies the interior exclusion volumes for supporting and restraining panels in the Panel FOUP, however, individual dimensions related to panel size and number of stored panels are specified by the Subordinate Standards.
 

This Standard defines three orthogonal reference planes as references for Panel FOUP dimensions.
