In the probe chamber, during the movement of the main jig in the X, Y, Z, and 0 directions, the alignment between the wafer and the probe of the probe card is performed via the alignment mechanism. Then, the main fixture moves in the X and Υ directions, and the initial device is positioned directly below the probe, and then the main fixture rises in the Ζ direction, and the device is in electrical contact with the probe, and the device is inspected. .

And a sub-clamp (not shown) for pre-alignment of the wafer W. In the loading chamber 1 1 , when the wafer transfer mechanism transfers the wafer w, the sub-clamp is pre-aligned, and then the wafer W is transferred between the probe chamber and the probe chamber 12. As shown in FIG. 1, the probe chamber 12 includes a mounting table 14 (hereinafter referred to as a "main jig") that moves a wafer in a horizontal direction and a vertical direction, and is disposed in the main jig 1 A probe card 15 at the top of the 4, and a registration mechanism (not shown) for aligning the probe 15A with the plurality of probe cards 15 and the wafer W on the master jig 14. In the probe chamber 12, after the alignment between the wafer W on the master jig 14 and the probe 15A of the probe card 15 via the alignment mechanism, the plurality of probes 15A and the crystal are made. The wire W is electrically contacted, and the electrical inspection of the wafer w is performed. When the electrical property inspection of the wafer W is performed, it is sent between the tester (not shown) and the probe card 15 via the test head T disposed on the probe card 15 above. The specific signal. Further, the probe card 15 is fixed to the opening of the head plate 16.

The same as -10- 200826213, make the top plate 1 4 A lift. The top plate 14A is formed by an insulating substrate such as ceramics, as shown in Fig. 2, and has a first conductor film 14C formed thereon and a second conductor film 14D formed on the lower surface thereof. The first and second conductor films 14C and 14D are formed, for example, of a gold film. Further, as shown in Fig. 1, a test head T used for measurement is electrically connected to the top plate 14A via a cable 18. As shown in FIG. 3, for example, the cable 18 is provided with a center conductor 18A which is a measurement voltage and a measurement path for measuring current, and a first external layer which covers the center conductor 18A via an insulating material. a conductor (for example, a mesh-shaped first shield conductor) 18B; and a second outer conductor (for example, a mesh-shaped second shield conductor) 1 8C that covers the first shield conductor 18B via an insulating material, and passes through the first The connector 19A is electrically connected to the test head T, and is electrically connected to the top plate 14A side via the second connector 19B. Then, as shown in FIG. 1 to FIG. 3, the center conductor 18 A of the cable 18 is electrically connected to the first conductor film 14C of the top plate 14A, and the first shielding conductor 18B is the second of the top plate 14A. The conductor film 14D is electrically connected. Further, the second shielding conductor 18C of the cable 18 is generally grounded as shown in Fig. 3 . Therefore, the test head T is configured to send a check signal to the wafer W via the probe card 15 when the probe card 15 is in electrical contact with the wafer W, and also via the cable 18 The center conductor 18 A is sent to the first conductor film 14 C on the top plate 14 A to inspect the signal, and the electrical characteristics of the wafer W are inspected. In addition, the static eliminating device 20 of the present embodiment is generally connected to the center conductor 18A and the ground line 2 of the cable 18, as shown in Figs. 1 and 3, as shown in Figs. 1 and 3, respectively. The grounding wiring 22; and the relay switch 23 provided in the diagram of the grounding wiring 22; and the grounding resistor 24 disposed between the grounding line 21 and the relay switch 23; and the supporting relay switch 23 and the grounding a support substrate 25 of the resistor 24; a switch controller 26 for controlling the opening and closing of the relay switch 23; and a housing 27 for accommodating components other than the switch controller 26, and configured to perform the wafer W At the time of inspection, under the control of the switch controller 26, the relay switch 23 is regularly opened and closed, and the static electricity charged to the top plate 14 is removed. The static eliminating device 20 is mounted on the head top plate 16 via the casing 27 as shown in Fig. 1 . As shown in FIG. 3, the relay switch 23 includes a coil 23A, a switch 23B disposed along the axial center in the line 圏 23A, and a case 23C accommodating the coil 23A, and according to the slave switch controller 26 Acting with the signal. Further, the coil 23 is electrically connected to the controller cable 28 via the wiring 23D. Controller cable 28 is electrically coupled to switch controller 26 via I/O port 28A. Further, one end of the switch 23B is electrically connected to the ground wiring 2, and when the coil 23A is biased based on the signal from the switch controller 26, the center conductor 18A of the cable 18 and the ground line The 2 1 is electrically connected, and when the biasing force of the coil 23 A is released, the electrical connection between the center conductor 18 A and the ground is released. The first shielding conductor 18B of the cable 18 is extended to the vicinity of the switch 23B via the wiring 22A, and is electrically connected to the casing 23C. Therefore, the switch 23B and the casing 23C are slightly set. The potential can suppress leakage current or electrical noise from the ground wiring 22 or the switch 23B. -12-200826213, the first shielding conductor 18B of the cable 18 is electrically connected to the second conductor film 18D on the lower surface of the top plate 14, so that the second conductor film 14D can be applied to the first conductor film 14D. The conductor film 14C has a slightly the same voltage. Thereby, the leakage current from the first conductor film 14C can be suppressed, and the measurement accuracy of the device can be improved. The switch controller 26 is constructed as a part of a controller made of a computer. The switch controller 26 is stored in the controller via a recording medium recording a program for carrying out the power-removing method of the present invention. Further, in the casing 27 of the static eliminator 20, the push switch 29 is mounted, and the operator presses the push switch 29 to apply force to the relay switch 23, thereby enabling the static elimination. The push switch 29 is electrically connected to the wiring 23D of the coil 23A via the diode 29A as shown in Fig. 3 . The push button switch 29 is not used when the wafer W is inspected, and is used for, for example, maintenance. Next, a description will be given of one of the embodiments of the static elimination method of the present invention using the static eliminating device 20, with reference to (a) to (c) of Fig. 4 . In the static elimination method of the present invention, the program is stored as a switch controller 26 in the controller via the recording medium as described above. In the case of performing the inspection of the wafer W, in the mounting chamber, the wafer transfer mechanism carries the wafer W out of the accommodating portion, performs pre-alignment at the sub-clamp, and then mounts the wafer W. (l〇ad) is placed on the main jig 1 4 that is in standby in the probe chamber 12. During the period in which the wafer W is placed on the top plate 14 A of the main jig 14 from the accommodating portion, as shown in FIG. 4( a ), the switch controller 2 6 is activated, and the relay switch 2 3 is activated. Force. By the biasing of the relay switch 23 by -13-200826213, the switch 23B is closed, and the first conductor film 14C of the top plate 14A is grounded via the center conductor 18A of the cable 18 and the grounding wiring 22. Thereby, the static electricity charged on the wafer W and the top plate 14A is removed via the top plate 14A. When the wafer transfer mechanism mounts the wafer W on the top plate 14A, the main jig 14 is moved in the horizontal direction after the wafer W is vacuum-absorbed on the top plate 14A. During this period, the main jig 14 operates in conjunction with the alignment mechanism to perform alignment between the wafer W and the probe 15 A of the probe card 15. During this period, the static electricity is charged on the wafer W and the top plate 14A. However, since the top plate 14A is grounded, the crystal is in a period until the wafer W is in contact with the probe 15A. The static electricity of the circle W and the top plate 14A is removed via the top plate 14A, so that no static electricity is charged on the wafer W. After the wafer W is aligned, the first device in the wafer W is positioned directly below the probe 15 A. At this position, the lift mechanism 1 4B of the master jig 14 is driven to make the wafer W Raise and bring the device into contact with the probe 15 A. Simultaneously with this contact, the switch controller 26 operates to eliminate the force applied to the relay switch 23, and the switch 23B is turned on, the ground of the top plate 14A is released, and the wafer W and the top plate 14A are interrupted. In addition to electricity. After the device is in contact with the probe 15A, the wafer W is overdrived via the elevating mechanism 14B of the main jig 14 to electrically contact the wafer W with the probe 15 A and from the tester. The test head T is sent to the probe card 15 for the inspection signal, and is also applied from the test head T to the first conductor film 14 - 200826213 1 4C on the top plate 14A via the center conductor 18A of the cable 18 As the voltage of the inspection signal, the electrical characteristics of the device are checked. At this time, the second conductor film 14D on the lower surface of the top plate 14A is also applied with a voltage which is slightly the same as that of the first conductor film 14C. Thereby, the leakage current from the first conductor film 14C can be suppressed, and the measurement accuracy of the lifting device can be improved. Further, since the second conductor film 14D on the lower surface of the top plate 14 is electrically connected to the casing 23 C via the first shielding conductor 18B and the wiring 22A of the cable 18, it can be provided in the grounding wiring. The switch 23B at 22 and the case 23C are set to be substantially equipotential, and it is possible to suppress leakage current or electrical noise from the ground wiring 22 or the switch 23B. If the inspection of the first device is completed, the top plate 14A is lowered by the elevating mechanism 14B, and the contact between the device and the probe 15A is released. Simultaneously with this falling operation, according to the command signal from the switch controller 26, the relay switch 23 is actuated to close the switch 23B, and the first conductor film 14 C of the top plate 14 is grounded, as shown in Fig. 4 (b). In general, the static electricity charged to the wafer W and the top plate 14A during inspection is removed via the top plate 14A. Then, the main jig 14 moves in the X direction or the γ direction, and the wafer W is indexed and transported. After the next device reaches the probe 15A, the top plate 14A rises through the lifting mechanism 14B, and The device is in electrical contact with the probe 15 5 A. The static electricity charged on the wafer W and the top plate 14A is removed from the top plate 14A during the period from the lower movement of the top plate 4A to the contact operation. Simultaneously with the contact of the device and the probe 15 A, the relay switch 23 is actuated according to the finger -15-200826213 from the switch controller 26, and the switch 23B is opened and interrupted from the top plate 1 4 A The power is removed. In this state, the inspection signal is sent from the test head T via the probe 15 A, and the electrical characteristic inspection of the above device is repeated. If the inspection of the last device in the wafer W is completed, the top plate 14A is lowered. Simultaneously with this falling operation, the switch 23B of the relay switch 23 is turned off in accordance with the command signal from the switch controller 26, and the wafer W and the top plate 14A are neutralized (refer to Fig. 4 (c)). Then, in order to receive the wafer W that has been inspected, the main jig 14 is moved to the side of the loading chamber 1 1 , and the wafer transfer mechanism that is in standby in the loading chamber 11 unloads the wafer W on the main jig 1 4 . After the wafer W is unloaded, the wafer transfer mechanism returns the wafer W to be inspected to the accommodating portion, and then the next wafer W is carried out from the accommodating portion. Further, the wafer transfer mechanism transfers the wafer W that has been pre-aligned by the sub-clamp to the main jig 14 that is waiting in the probe chamber 1 2 . After the wafer W is placed on the main jig 14 , the above operation is repeated to perform the inspection of the wafer W, and at the same time, when the wafer W is not in contact with the probe 15 A, the wafer W is performed. And the power removal of the top plate 14A. Further, a wafer transfer mechanism including two arms of the upper and lower sides may be used, and the wafer W may be carried out from the accommodating portion by one of the arms, and the wafer may be pre-aligned to complete the wafer to be inspected. W Standby, when the wafer W that has been inspected reaches the time of the wafer transfer mechanism, the wafer W is unloaded by the other arm, and then loaded by one of the arms. As described above, except for the time when the wafer W is in contact with the probe 15 A - 16 - 200826213, since the static electricity of the wafer w and the top plate 14 A is removed by 1 4 A, the electrostatic charging is performed on the crystal. The opportunity on the circle W can be the same amount of charge from the initial device to the last device. Therefore, the inspection results between devices are not biased from the beginning of the inspection, and the ability is not High inspection. Moreover, since the amount of charge on the wafer W is such that there is no damage to the device during inspection. As described above, in the present embodiment, the relay switch 23 having the grounding wire for grounding the main jig 14 is provided to the grounding wiring 22, and the switch for opening and closing the 23 is provided. The controller 26, and capable of performing a non-electrical contact with the probe 15 A, grounds the top plate 1 4 A of the main jig 14 by opening the relay, and removes the wafer plate 1 4 A The work of static electricity; and when the wafer W and the probe 15 A, the top plate 14A project is released by turning on the relay switch 23, so that the wafer W is accumulated during the inspection of the wafer W. Static electricity, even in the ultra-fine micro-circle W below the 6 5 nm process, can also improve the reliability of the inspection, and the damage of the wiring structure. Further, according to the present embodiment, the main jig 14A is connected to the test head T and the ground wiring 22 is connected to the center conductor 18A of the cable 18. Therefore, the cable conductor can be used. 1 8 A is used as the grounding wiring for the static elimination device 20, and further, according to the present embodiment, the cable through the top plate is rarely maintained until the last time, and the reliability is small. And the relay switch = the crystal prevention device that is almost unstructured when the wafer S 2 3 is turned off and the ground of the top electrical contact is electrically connected via the cable. 1 Shielding -17- 200826213 Body 18B Since the connection case 23C is electrically connected to the relay switch 23 via the wiring 22A, the switch 23B and the case 23C are set to be substantially equipotential, and the grounding wiring 22 or the switch can be used. The leakage current or electrical noise from 23B is suppressed. Further, since the first shield conductor 18B of the cable 18 is electrically connected to the second conductor film 14D on the lower surface of the top plate 14A, the second conductor film 14D may be applied in the same manner as the first conductor film 14C. The voltage can thereby suppress the leakage current from the first conductor film 14C and improve the measurement accuracy of the device. Further, since the relay switch 23 is connected to the push switch 29 and is configured to be manually operable, when an abnormality due to static electricity occurs during the inspection, etc., the push button switch can be used. The operation is to remove the static electricity of the wafer W by emergency evacuation. Further, in the above-described embodiment, the inspection device for moving the main jig (mounting table) with respect to the probe card has been described. However, the inspection device may be configured to move the probe card with respect to the mounting table. . Further, in the above embodiment, the static eliminator used in the inspection apparatus for inspecting the wafer W has been described. However, the present invention is also applicable to an inspection apparatus other than the wafer. [Industrial Applicability] The present invention can be suitably used in an inspection apparatus in the field of semiconductor manufacturing.
