Abstract:
An embodiment of a method for producing traceable integrated circuits includes forming on a wafer of semiconductor material functional regions for implementing specific functionalities of corresponding integrated circuits, forming at least one seal ring around each functional region of the corresponding integrated circuit, and forming on each integrated circuit at least one marker indicative of information of the integrated circuit. Forming on each integrated circuit at least one marker may include forming the at least one marker on at least a portion of the respective seal ring that is visible.
