INTEGRATED CIRCUIT SECURITY
First Claim
1. A semiconductor product comprising:
- a substrate having a self-assembly (SA) pattern, wherein the SA pattern has been initially created using a block copolymer (BCP) which has been annealed on the substrate, wherein the SA pattern is an information carrying security mark having a set of features with corresponding locations within the information carrying security mark which uniquely identify the semiconductor product.

Abstract
A semiconductor product includes a substrate having a self-assembly (SA) pattern. An initial SA pattern is created using a block copolymer (BCP) which has been annealed on the substrate. The initial SA pattern and/or an enlarged SA pattern derived from the initial SA pattern is incorporated into the semiconductor product. The SA pattern is an information carrying security mark having a set of features with corresponding locations within the information carrying security mark which uniquely identify the semiconductor product. In other embodiments of the invention a method and system for creating the semiconductor product are described.
