Abstract
An electrical component is formed with a directed self assembly portion having a random electrical characteristic, such as resistance or capacitance. The random pattern can be produced by using a directed self assembly polymer with guide structures 2 including randomness inducing features. The electrical components with the random electrical characteristics may be used in electrical circuits relying upon random variation in electrical characteristics, such as physically unclonable function circuitry. The electrical components may be resistors and/or capacitors.
