DEVICE AND METHOD FOR GENERATING IDENTIFICATION KEY |
摘要 |
Provided is a device for generating an identification key using a process variation during a manufacturing process of a conductive layer. The device for generating an identification key may include a plurality of conductive layers designed so as to be formed in a first region within a semiconductor chip, the density in which the plurality of conductive layers are disposed in the first region being at least a first threshold value and not more than a second threshold value, the first and second threshold values being less than a minimum density according to the design rules for ensuring that all of the plurality of conductive layers are formed in the first region; and a reader which provides an identification key by identifying if, among the plurality of conductive layers, a previously designated first conductive layer has been formed. |

1. A device for generating an identification key, the device comprising:
a plurality of conductive layers designed to be formed in a first region in a semiconductor chip, a density of the plurality of conductive layers disposed in the first region being equal to or greater than a first threshold and equal to or less than a second threshold, and the first threshold and the second threshold being less than a minimum density according to a design rule that ensures that all the plurality of conductive layers are formed in the first region; and a reader configured to determine whether a first conductive layer designated in advance among the plurality of conductive layers is formed and to provide an identification key. |
