Title: DEVICE AND METHOD FOR GENERATING IDENTIFICATION KEY BY USING SEMICONDUCTOR PROCESS
Abstract:
Provided are a device and a method for generating an identification key by using process variation in a semiconductor process. A semiconductor is manufactured by adjusting the gate side edge position of a contact such that a difference between the probability that the gate of a transistor is short-circuited from a drain or a source by the contact and the probability that the gate is not short-circuited is less than or equal to a predetermined critical value. 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 through the reading unit is detected, and the identification key is provided.
