Semiconductor device and semiconductor production management system

摘要

The present invention provides a semiconductor device furnished with tamper-resistant identification information by forming a circuit pattern 2 B which differs from one semiconductor chip to another in a semiconductor chip 2 packaged in a semiconductor device 1 in addition to an original circuit pattern 2 A and expressing the identification information by this circuit pattern 2 B and the invention further provides a semiconductor manufacturing management system targeted at a product mounted with this semiconductor device, capable of managing the product from the manufacturing to the mode of use of the semiconductor device.
