An integrated circuit (IC) includes a first circuit layer that includes a first wireless power transfer (WPT) device, a first chip electrically connected to the first circuit layer, and a first tracking circuit disposed in the first chip. The first WPT device may be configured to extract energy from an electromagnetic signal and provide an output voltage. The first tracking circuit may be powered by the output voltage of the first WPT device and may output tracking data in response to an instruction extracted from the electromagnetic signal.

Composite integrated circuits and methods for wireless interactions therewith

A composite integrated circuit (IC) includes a first circuit layer, a second circuit layer having a first chip and a second chip, and a first wireless power transfer (WPT) device in the first chip or the first circuit layer. The first WPT device generates a power supply voltage by extracting energy from an electromagnetic signal. A first tracking circuit in the second chip or the first circuit layer is powered by the power supply voltage from the first WPT device and stores or outputs tracking data in response to an instruction extracted from the electromagnetic signal.

A three-dimensional integrated circuit (3DIC) and wireless information access methods thereof are provided. The proposed 3DIC includes a semiconductor structure, and a wireless power device (WPD) formed on the semiconductor structure for wirelessly receiving a power for operating a function selected from a group consisting of probing the semiconductor structure, testing the semiconductor structure and accessing a first information from the semiconductor structure.
