CHIP ARRANGEMENT AND METHOD FOR CHECKING WHETHER A CHIP IS ARRANGED IN AN INTENDED CHIP CARRIER |
| 摘要 |
One embodiment describes a chip arrangement having a chip carrier; a chip which is arranged in or on the chip carrier; a light sensor arrangement; a transparent layer which covers the light sensor arrangement, the light sensor arrangement being set up to determine a light pattern of light received by the light sensor arrangement from outside the chip arrangement through the transparent layer; and a test circuit which is set up to check whether the light pattern matches a reference light pattern and to output a signal on the basis of the result of the check. |
