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.
Claims20
An electrical component having a portion with a shape corresponding to a random pattern to give said electrical component a random electrical characteristic.
A method of forming an electrical component with a random electrical characteristic comprising the step of forming at least a portion of said electrical component with directed self assembly to have a shape corresponding to a random pattern.
An electrical component comprising:
- at least one guide structure;
- and
- a directed self assembly portion with a shape controlled by said at least one guide structure, wherein
- said at least one guide structure has one or more randomness inducing features with a size greater than a manufacturing tolerance size for said guide.
