Description: TECHNICAL FIELD The present invention relates to a probe substrate for measuring a semiconductor integrated circuit, and more particularly to a probe for measuring a semiconductor integrated circuit for preventing a malfunction in a function test of a semiconductor integrated circuit due to current noise. It relates to a substrate. [Prior Art] Conventionally, this kind of probe substrate for measuring a semiconductor integrated circuit is a third type.
As shown in the figure, a large number of probes 3 are arranged along the edge of the opening 6 opened in the insulating plate 1, and the connection between each probe 3 and the integrated circuit measuring device is made by the copper foil printed pattern 2 on the insulating plate 1 or The connection was made by connection using a coaxial cable or the like. [Problems to be Solved by the Invention] In the measurement system of a semiconductor integrated circuit using the conventional probe substrate for measuring a semiconductor integrated circuit described above, if the range from the probe substrate to the semiconductor integrated circuit measuring device is included, In many cases, an excessive parasitic capacitance is added as compared with the actual use state. As a result, during the measurement of the semiconductor integrated circuit, noise is generated in the power supply line due to the charging and discharging of the parasitic capacitance, and this noise causes a malfunction of the semiconductor integrated circuit. An object of the present invention is to provide a probe substrate for measuring a semiconductor integrated circuit which has solved the above-mentioned problems. [Differences from the Prior Art of the Invention] In contrast to the above-described conventional probe substrate for measuring a semiconductor integrated circuit, the present invention connects an impedance element to each probe to measure the parasitic capacitance of the measurement system and the semiconductor integrated circuit to be measured. There is a difference in that generation of noise is suppressed by increasing the charge / discharge time constant. [Means for Solving the Problems] The semiconductor integrated circuit measuring probe substrate of the present invention is a semiconductor integrated circuit measuring probe substrate in which a plurality of probes are arranged on an insulating plate. An impedance element is inserted in series with a probe corresponding to an output terminal. Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. Embodiment 1 In FIG. 1, the same components as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted. An impedance element (a resistor 4 in this embodiment) is inserted in series with a probe 3 corresponding to an output terminal of a semiconductor integrated circuit to be measured provided on an insulating plate 1. In this case, assuming that the output impedance of the semiconductor integrated circuit to be measured is R 0 , the charge / discharge time constant T of the measurement system parasitic capacitance C P when the output signal is inverted is T = C P R 0 in the conventional example. In the case of this embodiment, T = C P (R 0 + R). As a result, the peak value of the transient current when the output signal is inverted is reduced, the noise of the power supply line of the semiconductor integrated circuit to be measured is improved correspondingly, and a malfunction during the function test can be prevented. (Example 2) In FIG. 2 (a), in the case of the present example, unlike the aforementioned example, a ferrite beads inductor 5 is used as an impedance element connected in series to the probe 3. FIG. 2 (b) shows an example of the impedance characteristic of the ferrite bead inductor 5. The impedance increases as the frequency increases, and the increase in the impedance is caused by the resistance of the ferrite bead inductor 5 caused by the loss. Since most of the components are used, abrupt changes in device output can be suppressed to prevent malfunction. In this case, unlike the above embodiment, the DC impedance is almost zero, so that there is an advantage that the measurement of the DC characteristics is not affected. [Effects of the Invention] As described above, according to the present invention, in a probe substrate for measuring a semiconductor integrated circuit, by inserting an impedance element in series with a probe, a parasitic capacitance of a measurement system during a functional test of the semiconductor integrated circuit is measured. This has the effect of preventing malfunction due to charging and discharging of.
