Abstract
Disclosed are embodiments of a method for randomly personalizing chips during fabrication, a personalized chip structure and a design structure for such a personalized chip structure. The embodiments use electronic device design and manufacturing processes to randomly or pseudo-randomly create a specific variation in one or more instances of a particular electronic device formed on each chip. The device design and manufacturing processes are tuned so that the specific variation occurs with some predetermined probability, resulting in a desired hardware distribution and personalizing each chip. The resulting personalized chips can be used for modal distribution of chips. For example, chips can be personalized to allow sorting when a single chip design can be used to support multiple applications. The resulting personalized chips can also be used for random number generation for creating unique on-chip identifiers, private keys, etc.
