We have proposed a wafer stacking technology to integrate various kinds of devices into three-dimensional (3D) SoC[1-6]. In 3D SoC, each circuit layer is stacked and electrically connected vertically using a huge number of vertical interconnection. Hence, we can dramatically increase the wiring connectivity, reduce the number of long wiring and integrate various kinds of devices with different fabrication process sequences into one chip. In this paper, we describe a 3D microprocessor test chip consisting of three circuit layers and demonstrate the basic operation of the 3D microprocessor.
