    • A vacuum chamber used for processing articles, such as integrated circuit wafers, display panels, and the like, has a small load lock chamber formed at an opening in a wall of the chamber by a moveable article supporting surface within the chamber and a cover outside of the chamber. The supporting surface and cover are sealed to the chamber wall when urged against it. Articles placed into the load lock chamber, when the cover is opened, are moved into the vacuum chamber for processing by moving the supporting surface away from the wall after the cover has been closed and a vacuum established in the load lock chamber. Articles are removed from the vacuum chamber in a reverse manner. Various mechanisms are described for moving the articles, including a particular robotic device that simultaneously swaps the positions of two articles between the supporting surface and a processing location within the vacuum chamber by first pulling the articles together and then rotating them in a half-circle. Integrated circuit wafers are preferably carried on a domed surface formed of wedge shaped pieces fit together on a frame, where the wedge shaped pieces and their wafers are individually removable from the frame for transfer to another frame at a different location.
    • 用于处理诸如集成电路晶片,显示面板等的制品的真空室具有通过室内的可移动物品支撑表面形成在室的壁的开口处的小的负载锁定室, 的房间。 支撑表面和盖子在被推压时密封到室壁。 当盖子被打开时,通过在盖子被关闭并且在装载锁定室中建立真空物之后将支撑表面从墙壁移开而将盖子打开时放置到装载锁定室中的物品移动到真空室中以进行处理。 物品以相反的方式从真空室中取出。 描述了用于移动物品的各种机构,包括特定的机器人装置,其通过首先将物品拉在一起,然后以半圆形的方式旋转,同时在支撑表面和真空室内的处理位置之间交换两个物品的位置。 集成电路晶片优选地承载在由楔形块形成的圆顶表面上,所述楔形块在框架上装配在一起,其中楔形片和其晶片可从框架单独移除,以在不同位置转移到另一框架。
