- Each of the first probe socket 290-1 and the second probe socket 290-2 faces and contacts an individual semiconductor device on the wafer.
- first contact terminal group 281-1 of the second probe socket 290-2 has a configuration to connect to the driver output pin S2 and the comparator input pin R2 through separate lines 102A and 102B. It may be applied to all terminals of the first contact terminal group 281-1.
- the third type semiconductor device must be tested under the condition that the probe 291 of the first probe socket 290-1 is not mounted. Therefore, it is desirable that the probe 291 be provided with a detachable structure.
- the third type semiconductor device is formed only on the position of the second probe socket 290-2 on the wafer, and is not formed at the position of the first probe socket 290-1. Tests can be performed one by one in the configuration shown. Here, it is necessary that the first type semiconductor device, the second type semiconductor device, and the third type semiconductor device existing on the wafer have their respective pads formed in the same positional relation, and that .
- FIG. 8 shows an embodiment in which the connection configuration of the second invention is applied to a probe card.
- the first probe socket 290-1 and the second probe socket 290-2 can be used to test two semiconductor devices of the first type and the second type on the semiconductor device at a time. it can. The reason is the same as that described with reference to FIGS. 2 and 3, and further description is omitted here.
- the third type of semiconductor device can be tested by the second probe socket 290-2 by setting the condition that the probe 291 of the first probe socket 290-1 is not attached.
- FIG. 9 shows a connection configuration proposed in the third invention.
- the connection configuration proposed here is a connection configuration to be applied to the case where the paired terminals of the data input / output terminals of the DUT are differentially switched between the operation mode and the non-operation mode at different timings.
- Such characteristics Semiconductor devices are present in graphics devices.
- connection structure that connects the first contact terminal group 281-1 and the second contact terminal group 281-2 of the second contact tool 280-2 to the pin electronics PE.
- the connection structure that connects the first contact terminal group of the second contact device 280-2 shown in FIGS. 1 to 5 to the pin electronics PE it corresponds to the number of data input / output pins of the DUT. Requires a number of drivers and comparators.
- the number of the driver and the comparator taka may be about half the number of the data input / output pins of the DUT.
- the lines 121A, 121B and 131A, 131B are matched to the characteristic impedance which is about twice the characteristic impedance of the other lines 120A, 130A. Need to be done. That is, if the characteristic impedance of the lines 120A and 130B is 50 ⁇ , the characteristic impedance of the lines 121A, 121B, 131A, and 131B must be about 100 ⁇ . If the characteristic impedance is converted from a 50 ⁇ to a 100 ⁇ parallel connection circuit at the branch point in this way, signal reflection will occur and the waveform quality will be degraded.
- terminals that operate at a time lag with each other by a switching control signal are connected by a crossover wiring, and one terminal is connected to a driver output pin provided in pin electronics. It connects the other terminal to the comparator input pin provided in the pin electronics and claims that the two terminals can be tested on a common line.
- FIG. 9 shows the embodiment. 280 shown in FIG. 9 indicates a contact device.
- Contact CNTs are arranged in this contact tool and provided, for example, by contacting, for example, pin-type external terminals of a DUT (not shown) with the contact CNTs. Each contact terminal is electrically connected.
- the contact terminals V1-1, VI-2, V2-1, V2-2, ..., VN-1, VN-2, and W1-1, Wl-2, W2 of the contact terminal group 281 are shown.
- the contact terminals that contact the pins that operate in pairs with each other are shown.
- These paired contact terminals are commonly connected to each other via crossover wiring 101B1-1-101B1-N and 101B2-1-101B2-N, and one end of each crossover wiring 101B, for example, 101B1-1 is connected to terminal T1-1.
- FIG. 9 shows the connections for two channels (ie, the second IO channel IOCH-2 has a similar connection). All of the input and output pins that operate in pairs with the DUT are connected in this way.
- one of the commonly connected pins of the DUT is controlled to an operating state, and a test pattern signal is applied from the dryno through the line 101A.
- the response signal can be fetched on the comparator side through the line 101C, and one pin can be tested.
- the other pin With one pin inactive, the other pin is switched to the active state. In this state, test the other pin. Then, in parallel with the test of the pair of terminals (for example, VI-1 and VI-2) by the IOCH-1, the test of the other pair of terminals (for example, Wl-1 and W1-2) by the IOCH-2 is performed. Therefore, a DUT with 32 pins can be tested on 16 channels. Since one pin and the other pin are cross-wired, the propagation delay seen from the driver side differs from the driver side, and the propagation delay seen from the comparator side also differs, as described above. For this reason, it is necessary for the semiconductor device test apparatus to determine in advance the difference between the two skews, and to consider the conditions for generating a test pattern corresponding to the difference in skew and the timing determination conditions on the comparator side.
- the lines 101A and 101C and the crossover wiring 101B can all be set to have a characteristic impedance of 50 ⁇ . As a result, there is no portion where the characteristic impedance is discontinuous in the middle of the line, and there is no risk of deteriorating the waveform quality.
- Figure 10 shows an example of waveform measurement.
- FIG. 10A shows the second contactor 280 in the configuration of FIGS. 1 to 8 according to the first or second invention.
- -2 shows the connection structure of the first contact terminal.
- FIG. 10B shows the connection structure proposed in the third invention.
- Figure 10C shows an example of waveform observation comparing these two connection structures. Waveforms a, b, and c shown in FIG. 10C represent the waveforms observed at the observation points (a), (b), and (c) shown in FIGS. 10A and 10B when a rectangular wave is applied from the driver IODR. As is clear from this waveform force, it can be understood that the impedance of the connection structure proposed in the third invention is continuously matched, so that the waveform is less deteriorated.
- the semiconductor device test apparatus and the device interface board according to the present invention are used in a semiconductor device manufacturing department or a semiconductor device development department.
