A method of making a secure integrated-circuit system comprises providing a first integrated circuit in a first die having a first die size and providing a second integrated circuit in a second die. The second die size is smaller than the first die size. The second die is transfer printed onto the first die and connected to the first integrated circuit, forming a compound die. The compound die is packaged. The second integrated circuit is operable to monitor the operation of the first integrated circuit and provides a monitor signal responsive to the operation of the first integrated circuit. The first integrated circuit can be constructed in an insecure facility and the second integrated circuit can be constructed in a secure facility.

An image sensor package according to an embodiment of the present technology includes: a solid-state image sensor; a transparent substrate; and a package substrate. The solid-state image sensor has a light-receiving surface including a light-reception unit and a first terminal unit, and a rear surface opposite to the light-receiving surface. The transparent substrate faces the light-receiving surface. The package substrate includes a frame portion, a second terminal unit, and a supporting body. The frame portion has a joint surface to be joined to the transparent substrate and includes a housing portion housing the solid-state image sensor. The second terminal unit is to be wire-bonded to the first terminal unit, the second terminal unit being provided in the frame portion. The supporting body is provided in a peripheral portion of the light-receiving surface or at a center portion of the rear surface and partially supports the light-receiving surface or the rear surface.
