Although the semiconductor industry has made great progress in the high -tech field, this industry is very vulnerable to the influence of counterfeit products. The global electronic product supply chain is estimated to be as high as the risk brought by counterfeit products each year.2000$ 100 million.The global chip shortage has enlarged this risk, because the shortage of components will force buyers to purchase from the gray market, so it is critical to identify whether the device is the original production.More importantly, since the new crown epidemic, the transaction volume of counterfeit and pirated products has continued to rise in various fields, and Microelectronics is one of the areas.
Fake chips will not be fake like before.Now, counterfeiters can accurately cloned genuine components so that fakes can reach the true level of falseness.Although genuine products will use a variety of anti -counterfeiting technologies, such asRFIDTags and holographic diagrams, but they still cannot stop semiconductor devices being copied.Therefore, the industry urgently needs to develop new methods and improve existing technology.
Below, let's understand some highly reliable authenticity of product authenticity. They are expected to greatly increase the difficulty of fraud.
In the material molecular structure of the production chip, there will be random and uncontrollable micro -defects, so each chip is unique.This uniqueness can be used to prove the authenticity of the product.Physical inaccurate function (PUF) The use of these naturally formed random fluctuations.PUFIt is a device with unique and non -repeated physical characteristics. These physical characteristics can be converted into available information.Use random physical characteristics to perform genuine verificationPUFIt is more advantageous than the existing optical solution (such as holographic chart), becausePUFThe complexity of manufacturing and replication is inherently asymmetric.based onPUFThe genuine verification system uses chips made through inherent random craftsmanship, and such chips are almost impossible to be cloned.becausePUFThe system is difficult to copy, so this method can ensure extremely high security, which is very suitable for anti -counterfeiting applications.
Quantum dot (QD) It is a semiconductor nanoparticles that can show high -efficiency optical glow within a wide range of adjustable colors, so that it can effectively give unique optical characteristics.Therefore, the anti -counterfeiting characteristics based on quantum dots are inherently difficult to copy and can be used to combat counterfeiting behaviors.The randomly deposited quantum dot matrix can be packaged in a transparent polymer to form labels.Quantum computers use light instead of charge to store and carry information.According to the law of quantum mechanics, a photon can exist in two different places at the same time.Therefore, a single photon can act as a quantum position or quantum bit, compared to the binary position (limited to0or1) You can carry more information.
This technology has been practically applied.For example, nanotechnology company headquartered in New MexicoUbiquitous Quantum Dots(Referred toUbiQD) A technology company that specifically produces anti -counterfeiting ink with SwitzerlandSICPA SARecently deepened cooperative relations and jointly developed basedUbiQDAnti -counterfeit ink of quantum dot technology.This cooperation will help the industry's advanced optics and machine readable functions with the combination of counterfeit ink combination as a carrier.
At the same time, the National Standard and Technology Research Institute (NIST) Research and staff also connect the mini -chip quantum dot with miniature waveguide (guide light transmission circuit) without obvious strength loss.This hybrid consists of two devices, which were originally built on one independent chip.其中，第一个yesNISTThe designed and manufactured arsenide semiconductor device, which carries the quantum dot and directly imports the single light produced by the quantum dot into the second device, that is,UCSBDeveloped low -loss silicon nitride waveguide.

FormulateAS6081The purpose of the standard is to cope with the increasingly fake and inferior electronic components in the aerospace supply chain. These components constitute a major performance, reliability and security risk.AS6081The standards stipulate various requirements and practices to reduce the risk of purchasing, receiving and selling counterfeit and inferior components, so that customers can fully trust their supply chain.AS6081是ANAB(National Affairs Commission of the National Standard Society) Foundation in the roster.ANABIt is a non -governmental organization that provides certification services and training for public and private sector organizations, and provides services for global markets.
In order to be able to achieve automatedAS6081External visual inspection and electrical test requirements in anti -counterfeiting standards, startupsChiplyticsAnd many other companies have promised to speed up the weekly rotation and provide more data -driven evaluation.ChiplyticsProprietary technologyChiplytics OneEach chip that enters the key system can be screened to combat counterfeiting behaviors, ensure the safety and compliance of semiconductor products, and enable global electronic component trade and transaction activities to run safely.
This technology is executed by automated semiconductor quality to ensure the product, and analyzes by collecting the unique electronic characteristics and images of each chip to determine whether the chip is genuine and intact.This is also a detection platform that combines electrical and optical testing. It can detect tiny differences by establishing a data set to identify cloning, fake or damaged chips.The company plans to use these data sets and its proprietary software to help companies purchase and test before installing chips into high reliability systems to prevent high -cost recalls, thereby building trust with customers.ChiplyticsTest non -invasive methods to detect abnormalities using machine learning.This product uses power spectrum analysis (PSA) Come widely evaluate homogeneity and identify abnormal values.As long as you need to set up work, you can complete the data collection in a few milliseconds to achieve larger coverage and higher throughput.
Taroz (Taroz (THz) The wavelength of radiation is between microwave and visible light.Non -conductive materials that are often used for components such as semiconductor chips are transparent to Taehzbo.With this principle, Korea Asia University (Ajou University)andPanopticsThe company's researchers have developed a fast three -dimensional (3D) Flying time imaging tools, use Targez (THz) Time -spectrum technology detects packaging semiconductor chips.By using phase information at the same time, this scheme can detect and identify the defects in the packaging chip.
The main challenge of counterfeit electronics is how to find them out.To this end, Israel StartcanceCybordA pure software solution was proposed.This solution uses the existing hardware on the production line to obtain the top and bottom images of the components used in use, and then analyze these images through artificial intelligence software with the help of a huge database to detect whether the components are fraud, damage, corrosion, corrosion, and corrosion, andLoom or other abnormalities.Even if the component is tested and flawless, the company will write down the positioning position of each device and the final installationPCBOr products, and check whether there are counterfeit components during the product assembly process.
CybordThe software solution can be monitored in real timeSMTThe stickers on the production line prevent unqualified electronic components from entering the product assembly process, and at the same timeOEMProvide visibility and traceability.Utilizing artificial intelligence and big data, this scheme can solve the problem of component defects during the sticker and before the return welding, thereby avoiding the repurchase and improving product reliability.
Artificial intelligence has developed to the level of identifying these counterfeit device.CybordVisualized software can verify the authenticity of each component by measurement value, date code, batch code, and batch number.Of course, a major challenge facing this solution is to find enough data.CybordIt claims that its database brings up the data of billions of electronic components, which can be analyzed every month2.5100 million components.
