Abstract(in English) | The increases of signal propagation delay and power consumption by interconnections in LSIs make it difficult to achieve a high performance LSI with low power consumption. To solve such interconnection problem, we have developed a three-dimensional (3D) integration technology based on wafer bonding method. We can reduce the pin capacitances and the wiring length by using this 3D integration technology. Therefore, we can increase the signal processing speed and decrease the power consumption. We have fabricated several prototype 3D LSI chips such as image sensor chip, shared memory, artificial retina chip, and microprocessor chip using this technology. In the wafer-on-wafer 3D integration technology, however, the overall chip yield exponentially decreases with an increase in the number of stacked layers. To solve such problem, we have proposed a new super-chip integration technology based on the reconfigured wafer-on-wafer bonding. Many chips are simultaneously aligned and bonded onto lower chips with high alignment accuracy using a self-assembly technique in a super-chip integration technology. |
