A worst-case temperature calculation unit calculates, based on heat value information of each layer of a three-dimensional integrated circuit to be designed and stack structure information of the three-dimensional integrated circuit, a worst-case temperature of a layer during operation that is targeted for logic synthesis. A logic synthesis library selection unit selects a library appropriate for the calculated worst-case temperature. A logic synthesis unit performs logic synthesis on the targeted layer with use of the selected library.

An integrated circuit is provided with a substrate, an electrode, two diffusion areas, and a resistance heater. The substrate includes a first surface and second surface that are substantially parallel to each other. The electrode is laminated onto the first surface. The two diffusion areas are disposed within the substrate in the vicinity of the electrode to form one transistor with the electrode. The resistance heater is located on an area of the second surface across the substrate from the electrode. The resistance heater produces heat by allowing electric current to flow.

Each chip in a three-dimensional circuit includes a pair of connections, a test signal generation circuit, and a test result judgment circuit. The connections are electrically connected with an adjacent chip. The test signal generation circuit outputs a test signal to one of the connections. The test result judgment circuit receives a signal from the other of the connections and, from the state of the signal, detects the conducting state of the transmission path for the signal. Before layering the chips, a conductor connects the connections to form a series connection, and the conducting state of each connection is detected from the conducting state of the series connection. After layering the chips, the test signal generation circuit in one chip outputs a test signal, and the test result judgment circuit in another chip receives the test signal, and thus the conducting state of the connections between the chips is tested.
