Claim 12:
13. A method of flipping a substrate, comprising:
receiving the substrate in a load lock chamber, the load lock chamber comprising a module for flipping the substrate, the module comprising:
a clamp assembly for securing a substrate placed in a first plane;
a first motor assembly coupled to the clamp assembly for rotating the clamp assembly around a first direction that is parallel to the first plane;
a second motor assembly coupled to the first motor assembly for raising and lowering the first motor assembly and the clamp assembly in a second direction that is perpendicular to the first plane; and

a slide coupled to the clamp assembly on a side opposite the first motor assembly in the first direction, wherein the slide comprises a bearing support that supports:
rotation of the clamp assembly by the first motor assembly around the first direction through a rotatable bearing; and
raising and lowering of the first motor assembly by the second motor assembly in the second direction; and

flipping the substrate in vacuum.
