The difference in shrinkage and expansion between the high-dielectric layer and the upper and lower electrodes in the horizontal direction increases, causing separation between the capacitor section and the printed wiring board, resulting in the wiring of the printed wiring board I guess that it was disconnected.
- Example 10 A cycle test similar to the evaluation test 2 was performed on the printed wiring boards of 0 to 16 for 500 cycles and 100 cycles. After the heat cycle, an IC chip (clock frequency: 3.73 GHz, FSB: 106 MHz) was mounted and the presence or absence of malfunction was confirmed as in Evaluation Test 1. The results are shown in Table 1.
- the present invention is based on Japanese patent application No. 2 0 0 4-1 8 8 8 5 5 filed on June 25, 2004, all of which are incorporated herein.
- the Industrial applicability is based on Japanese patent application No. 2 0 0 4-1 8 8 8 5 5 filed on June 25, 2004, all of which are incorporated herein.
- the printed wiring board of the present invention is used for mounting a semiconductor element such as an IC chip, and is used in, for example, an electrical industry or a communications industry.
