- the semiconductor wafer 1 and the thread of 1 are finished, the semiconductor wafer 1 is unloaded from the plasma section by the transfer robot 41 and transferred to the wafer mount section, and the transfer robot 4 After vacuum suction of the back surface of the semiconductor wafer 1 by 7, the vacuum suction surface of the semiconductor wafer 1 is changed and the circuit formation surface is vacuum suctioned.
- a semiconductor wafer 1 is attached to a dicing tape fixed and attached to an annular frame with its circuit forming surface as the upper surface, and then the semiconductor wafer 1 with its circuit forming surface as the upper surface is attached to the dicing tape. Adhere and peel off the adhesive tape BT1. Thereafter, the semiconductor wafer 1 is transferred to the unloader 38 in the wafer mount unit, and the semiconductor wafer 1 is taken out from the wafer mount unit and returned to the hoop.
- the semiconductor wafer 1 can be processed from the back ground to the wafer mount in a short time, and after the stress relief, the semiconductor wafer 1 is continuously applied to the back surface of the semiconductor wafer 1. 3 Since the broken frame layer 3 6 is formed, it is possible to prevent contamination impurities from entering from the back surface of the semiconductor wafer 1.
- the first to fourth methods are exemplified in the second embodiment.
- the present invention is not limited to this, and the method from the back surface of the semiconductor wafer is used.
- Other technologies that can prevent the entry of contaminating impurities can also be applied. 3 ⁇ 4 business availability
- the present invention is performed after a pre-process for forming a circuit pattern on a semiconductor wafer and inspecting each chip one by one, and can be applied to a post-process for assembling a chip into a product.
