The purpose of this creation is to provide a kind of wafer electro-metal fixture, the second elastic electrical contact element and the conductive layer on the wafer are perpendicular to the wafer conductive coating layer. It is possible to avoid the poor conductivity caused by the uneven plating layer when the horizontal level of the wafer is touched by the conventional technology, resulting in poor quality of the electrographic recording. And the purpose of this mouth--the purpose of providing a kind of wafer ejector, which uses the vacuum adsorption fixed side: the type 'because of fresh pressure measurement' is not easy to cause wafer deformation or damage, in addition, this creation Adding a vacuum detection device to the fixture can confirm that the elastic sealing element is completely in close contact with the wafer before the product is electroplated, so that the leakage of the liquid money does not occur during the electric chain process, resulting in poor yield, which is conducive to mechanization. Self-touch production, simplifying the entire process steps.

A first type of gasket is disposed around the circular opening 32. The periphery B of the W is further disposed with the first elastic sealing member 34. For example, the bottom surface of the upper cover 14 is provided with a conductive recombination %. As shown in FIG. 4, it includes an annular conductive base 38 of the bottom surface of the 14; The element 40 and the plurality of second-and-elastic first elastic-elastic electrical contact elements 42 in the garment-like conductive base (10) can be placed on the wafer carrier 16 A flexible shirt is considered to be a probe. When the upper cover is provided, the elastic electrical contact element 40 will be in vertical contact with the conductive ring 24, and the 7th M357020 second elastic electrical contact element 42 will be in vertical contact with the conductive layer on the wafer (in the figure). Not shown), the conductive ring 24, the first-elastic electrical contact element 4, the annular conductive base 38, and the second elastic electrical contact element form a conductive path. In addition, since the creation is applied to the electroplating process, the material of the wafer carrier and the upper cover are both 采- the text of the corrosion button material. Moreover, the present invention uses an elastic electrical contact element as an electrode, so that it is possible to adjust the stress of the surface resistance of the wafer surface of the component. «Monthly refer to Figure 5 (a) ~ 5 (8), which is a schematic diagram of the electric charge of the wafer key fixture of this creation.

The diameter of the circular opening of the upper cover 14 is smaller than the diameter of the wafer. The surrounding turns of the wafer 44 will be covered by the upper cover 14. Then, by vacuum valve device and through the through hole, the vacuum of the upper cover true jade region 18, the sealing member 22, the first 〇_elastic sealing member 26 and the second 〇_elastic sealing member 34 are vacuumed. The upper cover 14 is vacuum-adsorbed onto the wafer carrier η. At this time, the 'first elastic electrical contact element 4' is in vertical contact with the conductive ring 24, and the second elastic electrical contact element 42 will be in vertical contact with the conductive layer on the wafer 44 (not shown) to form a conductive path. . • Subsequently, the wafer plating jig 10 of the wafer 44 can be immersed in the battery liquid, and the conductive ring 24 is connected to the negative electrode of the power source for electroplating.
