Buzzy new tech trends including the industrial metaverse, 5G wearables, printed electronics, and satellite-to-cell services may be held back by global market volatility, according to a report from the analyst firm ABI Research. “War, inflation, political upheaval,...

Faced with shortages? Remain vigilant against counterfeit

EMS Now says there are numerous reasons why counterfeit parts surface, and companies need to be particularly vigilant during supply chain constraints, where low levels of required supply increase the pressure to access the open market. "Counterfeits components are...

‘Doping’ to combat counterfeit electronics

Oct 29, 2021

The National Institute of Standards and Technology (NIST) joins the race to thwart a new crop of counterfeiters who are trying to take advantage of the current global chip shortage, writes Source Today.

“Using a technique called ‘doping’, NIST scientists use small clusters of ‘foreign’ atoms of a different element from those in the device. Those foreign atoms are implanted just beneath the surface and alter the electrical properties of the topmost layer without harming it, creating a unique label that can be read by an electronic scanner,” reports the article.

The implanted atoms alter the arrangement of silicon atoms just beneath the surface of the wafer. These silicon atoms, as well as those that reside throughout the wafer, are arranged in a repeating geometric pattern known as a lattice. Each silicon lattice acts like an electrical circuit with a certain impedance, the AC (alternating current) equivalent of resistance in a DC (direct current) circuit, according to the NIST.
