Abstract
Provided are a device and a method for generating an identification key by using a process variation in a semiconductor process. A semiconductor is manufactured by adjusting a gate side edge position of a contact such that a difference between a probability that a gate of a transistor is shorted from a drain or a source by the contact and a probability that the gate is not shorted is less than or equal to a predetermined threshold. When the manufactured semiconductor does not have a separate process, whether there is a short circuit between the gate and the drain or the source is stochastically generated by the process variation, whether there is a short circuit is detected through a reader, and an identification key is provided.
