Patent Number: 
Section: claims

1. An operation stage system for edge and backside substrate inspection and review, comprising:a supporting frame to sustain the weight of the system;a stage to adjust variation of a focus of an e-beam image in z (vertical) direction;a station to adjust variation of a focus of the e-beam image in X and Y (horizontal) direction;an electrostatic chuck to hold the substrate by electrostatic force;a pendulum stage to mount the electrostatic chuck, the pendulum stage can swing from 0° to 180° while performing top bevel, apex and bottom bevel inspection or review; anda rotation track for the pendulum stage, which provides support and stabilizes the pendulum stage during the edge inspection and review. 2. The operation stage system of claim 1, wherein the electrostatic chuck has ability to rotate to a desired angle with respect to a substrate notch for edge inspection and review. 3. The operation stage system of claim 1, wherein the electrostatic chuck holds the substrate in such a way that the rotation axis of the pendulum stage consists of the tangent of upper edge of the substrate. 4. The operation stage system of claim 1, wherein the electrostatic chuck is mounted on the pendulum stage. 5. The operation stage system of claim 1, wherein the diameter of the electrostatic chuck is smaller than that of the substrate. 6. A method for edge and side substrate inspection and review comprising:adjusting for variation of a focus of an e-beam image in a vertical direction;holding the substrate by electrostatic force;adjusting the variation of the focus of the e-beam image in a horizontal direction; andswinging the substrate from 0° to 180° while performing top bevel, apex and bottom bevel inspection and review. 7. The method of claim 6, wherein an electrostatic chuck has ability to rotate to a desired angle with respect to a substrate notch for edge inspection and review. 8. The method of claim 6, wherein an electrostatic chuck holds the substrate in such a way that the rotation axis of a pendulum stage consists of the tangent of upper edge of the substrate. 9. The method of claim 6, wherein an electrostatic chuck is mounted on a pendulum stage. 10. The method of claim 6, wherein the diameter of an electrostatic chuck is smaller than that of the substrate.
