Abstract

PURPOSE:To effect the analysis of operation failure at sample production rapidly, accurately and easily by bringing the comb-form metal patterns which are exposed on the uppermost layer part of the element in close approach to each other and energizing with pressure-touching said close approach part from the outside of the element with a probe. CONSTITUTION:The comb-form metal patterns 12a and 13a are the wiring connected with a metal pattern 11a. If the metal patterns 11a-13a are designed at a time of designing masks and are incorporated in the position of a switch 6, a capacitor C can be added in point (d) easily by energizing with pressure-touching the metal pattern with a probe when analyzing failures of IC to deform the metal pattern. Consequently, because there is no need of making a mask newly, days for development and cost for fabrication of masks can be saved and the accurate and rapid analysis of operation failure is possible.

In the static transfer holding circuit shown in Fig. 4, a design error was made when designing the mask, resulting in Q, as shown in Fig. 5(b).
If a section 5 is created where the Q clock signals overlap, a situation will occur in the case where the input data is directly output to the output end. Note that FIG. 5(a) is a time chart when no tube removal condition occurs. In such a case, it is sufficient to widen the interval between the Q clock signal and the Q clock signal to eliminate signal overlap.

However, this method has the disadvantage that it is necessary to make a new mask, which wastes development days and mask production costs. Furthermore, if all failure analysis is performed using the needle wheel method shown in Fig. 2, it is necessary to always keep the probe 1t in contact with the fully bent wiring with the same pressure, and when slight vibrations occur, the probe 1 must always be in contact with the wire. It is difficult to keep gold in contact with the same pressure. Also, when capacitor C1 shown in Figure 2 is connected, terminal 2 is connected to probe 1 and terminal 3 is connected to ground (GND), but since the needle wheel is normally at ground level, , because extra stray capacitance is added between the probe 1 and the IC element, it is impossible to add the desired capacitance value89, and an accurate and quick malfunction analysis cannot be performed.
