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.
Claims20
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.
A method for manufacturing a semiconductor product comprising:
- creating a self-assembly (SA) pattern on a substrate, wherein the SA pattern has been initially created using a block copolymer (BCP) which has been annealed on the substrate;
- scanning the SA pattern to capture an image of the SA pattern;
- storing data from the SA pattern in a computer system;
- and
- providing the SA pattern on the semiconductor product;
- 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.
Apparatus, comprising:
- a processor;
- a scanner;
- a computer memory holding computer program instructions executed by the processor, the computer program instructions comprising:
- program code, operative to receive an image of a self-assembly (SA) pattern on a substrate from the scanner, wherein the SA pattern has been initially created using a block copolymer (BCP) which has been annealed on the substrate;
- program code, operative to store data from the SA pattern in a computer system;
- and
- program code, operative to associate the SA pattern data with the semiconductor product;
- 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.
