IBM Pushes Beyond 7 Nanometers, Uses Graphene To Place Nanomaterials on Wafers
An anonymous reader shares a report: Four years ago, IBM announced that it was investing $3 billion over the next five years into the future of nanoelectronics with a broad project it dubbed "7nm and Beyond." With at least one major chipmaker, GlobalFoundries, hitting the wall at the 7-nm node, IBM is forging ahead, using graphene to deposit nanomaterials in predefined locations without chemical contamination. In research described in the journal Nature Communications, the IBM researchers for the first time electrified graphene so that it helps to deposit nanomaterials with 97% accuracy. "As this method works for a wide variety of nanomaterials, we envision integrated devices with functionalities that represent the unique physical properties of the nanomaterial," said Mathias Steiner, manager at IBM Research-Brazil. "We also can envision on-chip light detectors and emitters operating within a distinct wavelength range determined by the optical properties of the nanomaterial." As an example, Steiner explained that if you wanted to modify the spectral performance of an optoelectronic device, you could simply replace the nanomaterial while keeping the manufacturing process flow the same. If you take the method one step further, you could assemble different nanomaterials in different places doing multiple passes of assembly to create on-chip light detectors operating in different detection windows at the same time.Read more of this story at Slashdot.
