An integrated circuit (IC) package includes a substrate, a ground line, and an encoded region. The encoded region provides information based upon selective deposition of solder balls electrically coupled to the ground line.
摘要:
In the manufacturing process of a semiconductor integrated circuit device, a plurality of identification elements having the same arrangement are formed and the relation of magnitude in a physical quantity corresponding to variation in the process of the plurality of identification elements is employed as identification information specific to the semiconductor integrated circuit device.
摘要:
Disclosed is a method for the forgery-proof identification of individual electronic subassemblies. According to said method, the changes in the status of certain storage locations of a memory (2) of an individual electronic subassembly (1) resulting from a specific breakdown of one or several auxiliary functions of said memory (2) are determined, and said changes in status are compared to predetermined memory-characteristic reference changes in the status of specific storage locations of the memory (2) regarding the identity thereof, said reference changes resulting from the specific breakdown of the auxiliary function of the memory (2) of the electronic subassembly (1).
摘要:
The invention concerns the generation of a chip identifier (2) bearing at least one integrated circuit, which consists in providing a cutout of least one conductive path (4) by cutting the chip, the position of the cutting line (3) relative to the chip conditioning the identifier.
