Deep Learning Secures Chips Against Counterfeits


WEST LAFAYETTE, IN — The semiconductor in- dustry has grown into a $500 billion global market over the last 60 years. However, it is faced with dual challenges: a profound shortage of new chips and a surge of counterfeit chips, introducing sub-


stantial risks of malfunction and unwanted sur- veillance. A team at Purdue University have developed a


patent-pending optical counterfeit detection method for chips used in semiconductor devices. The method is called RAPTOR, or residual at-


tention-based processing of tampered optical re- sponses. It leverages deep learning to identify tam- pering. It improves upon traditional methods, which face difficulty in scalability and discriminat- ing between natural degradation and adversarial tampering.

and says several techniques have been created to affirm semiconductor authenticity and detect coun- terfeit chips. “These techniques largely leverage physical security tags baked into the chip function- ality or packaging,” he says. “Central to many of these methods are physical unclonable functions

SANTA CLARA, CA — TEX- MAC, the exclusive authorized distributor of Takaya flying probe test systems in North and South America, will be exhibit- ing highlights of its advanced technology at SMTA Internation- al 2024. In the booth, a tabletop video will illustrate features of the APT-1600FD system and promote features including Takaya’s FastTrack CAD conver- sion software. FastTrack CAD conversion software is a fully in- tegrated solution from CAD im- port to final test of products. Takaya’s APT-1600FD ad -


vanced flying probe test system for assembled PCBAs provides average head-speed increases of up to 50 percent with throughput improvements of 30 to 50 percent over existing models. As part of the Plus Infinity

suite, FastTrack ODB++ saves time and eliminates unnecessary work. The conversion can be based on various factors includ- ing a comparison of differences


in the files. If an existing test program is generated from an ODB++ file, then FastTrack ODB++ is able to compare a re- vised ODB++ with an existing one and convert only the part


Flexible Circuits with ... Silk?


RICHLAND, WA — After thou- sands of years as a highly valu- able commodity, silk continues to surprise. Now it may help usher in a whole new direction for mi- croelectronics and computing. While silk protein has been


deployed in designer electronics, its use is currently limited in part because silk fibers are a messy tangle of spaghetti-like strands. Now, a research team led by

scientists at the Department of Energy’s Pacific Northwest Na- tional Laboratory has tamed the tangle. They have achieved a uniform two-dimensional (2D) layer of silk protein fragments, or “fibroins,” on graphene, a car- bon-based material useful for its excellent electrical conductivity. “These results provide a re-


producible method for silk pro- tein self-assembly that is essen- tial for designing and fabricating silk-based electronics,” says Chenyang Shi, the study’s lead
