Abstract
Some examples described herein relate to protecting an integrated circuit (IC) structure from imaging or access. In an example, an IC structure includes a semiconductor substrate, an electromagnetic radiation blocking layer, and a support substrate. The semiconductor substrate has a circuit disposed on a front side of the semiconductor substrate. The electromagnetic radiation blocking layer is disposed on a backside of the semiconductor substrate opposite from the front side of the semiconductor substrate. The support substrate is bonded to the semiconductor substrate. The electromagnetic radiation blocking layer is disposed between the semiconductor substrate and the support substrate.
