At this time, the surface A of the test device is oriented toward the image sensor 22Q. It can be effectively from the front of the chip I60 (front -side) The defect of the integrated circuit is measured. Thus, although the wafer 160 has multiple metal layers, the front and back of the wafer 160 can be detected separately due to the test device provided by the present invention. The test is to effectively analyze the failure of the chip i 60. It is called the reference ..., Figure ^ A, the picture shown by the present invention is provided according to the present invention.

Among them, in a preferred embodiment, more It can be between the open slot area 110 and the solder pad 150, on the surface a of the test device 101, A power ring 6 10 and a ground ring 620 are formed to reduce the complexity of the electrical connection. The ground ring 620 is adjacent to the open slot area 110 and the power ring 61 and serves as the chip 160. The upper component and the circuit are used for grounding; and the power ring 6 10 is located between the plurality of welding rings 150 and the ground ring 6 2 0 and can be divided into at least one section to provide at least one set of voltage. For example, in the sixth diagram A, the power ring 610 can be divided into four sections, so as to provide four different voltages at the same time, and provide components and circuits to be connected on the chip 160. When the voltage required by the component or circuit on the chip 160 is the same as any one of the four voltages, it can be connected to the section of the power ring 610 with the same voltage nearby. This can reduce the complexity and difficulty of connecting the wires 155. As for the sixth diagram B, the structure of the surface B of the test device 101 is shown. The open slot area 1 10 is covered by the supporting plate 140. Compared with the conventional technology, the test device provided by the present invention has many advantages. First, by using the test device provided by the present invention, the front side and back side of the integrated circuit wafer can be directly analyzed for failure, thereby avoiding the cause of the increase in the number of multiple metal layers. Hot spots (hot spots) generated by defects are difficult to detect by image sensors. In addition, for more precise high-integration wafers, using the test device provided by the present invention can effectively detect the extremely small π-piece 4 heating phenomenon, so it can assist in pre-empting possible failures (read first) Note on the back, please fill in this page again) ©! Installation · -β Λ ----: -------- B7 —__ 5. Description of the invention () A chip with a low operating life. In addition, since the size of the open slot area is slightly larger than that of the wafer, the test provided by the present invention can be easily used for various purposes. There is no need to change the design specifications with the size of the chip, so the cost of the process can be saved. In addition, by using the through-hole design of the pad and the probes of the testing machine to perform the electric chip test, compared to the traditional technology, a large number of chips can be subjected to standard functional tests (functional, test) '. Reduce the production of products from the production line 'reducing time into __. This. Although the present invention is explained as above with a preferred example, the spirit and the inventive substance of the present invention are limited to this embodiment. In the present invention, the listed embodiments are compared using this test. However, for those skilled in this field, when using this test procedure, the modifications without departing from the spirit of the present invention should be included in the scope of patent application described below. 11 The size of the test device in the test device. The test load is equipped with a t-connection, which can be light and direct (prototype is not limited to the market when it is prototyped.
