    摘要: A device and system for thin wafer cleaning is disclosed. A preferred embodiment comprises a spin chuck having at least three holding clamps. A thin wafer with a wafer frame is mounted on the spin chuck through a tape layer. When the holding clamps are unlocked, there is no interference with the removal and placement of the wafer frame. On the other hand, when the holding clamps are locked, the holding clamps are brought into contact with the outer edge of the wafer frame so as to prevent the wafer frame from moving laterally. Furthermore, the shape of the holding clamps in a locked position is capable of preventing the wafer frame from moving vertically.

    摘要: A method includes bonding a wafer on a carrier through an adhesive, and performing a thinning process on the wafer. After the step of performing the thinning process, a portion of the adhesive not covered by the wafer is removed, while the portion of the adhesive covered by the wafer is not removed.
