Abstract:
A method for transferring substrates in a system, comprising:a) retrieving a first substrate with a robot blade: b) supporting the first substrate on a first substrate supporting surface of the robot blade, wherein a primary orientation of the first substrate is in a first plane; c) retrieving a second substrate on a second substrate supporting surface of the robot blade, wherein a primary orientation of the second substrate is in one of the first or a second plane, the second plane being substantially perpendicular to the first plane; and d) delivering one of the substrates supported on one of the substrate supporting surfaces while supporting the other substrate on the other substrate supporting surface, wherein at least one of the first or second substrates is rotated to a secondary orientation between retrieval and delivery, the secondary orientation being substantially perpendicular to the primary orientation of the at least one substrate.
