RESEARCH TRIANGLE PARK – Just two weeks after IBM announced the world’s first 2 nanometer semiconductor chip, a consortium including MIT says it’s developed a 1 nanometer chip.
The enws came this week in a report at Nature.
Partners include Taiwan Semiconductor Manufacturing Company (TSMC) – a major chip producer – the National University of Taiwan (NTU) and Massachusetts Institute of Technology.
According to the report, ” the use of semi-metal bismuth (Bi) as the contact electrode of the two-dimensional (2D) material can greatly reduce the resistance and increase the current. This can achieve energy efficiency close to the existing physical limits of semiconductor sizes,” says U.K. news site Verdict.
Current size on many chips is 5 NM and 7 NM.
IBM said its 2 NM design would deliver more processing power and lower energy use in a wide variety of devices.
The world faces a shortage of chips as demand grows for everything from autos to internet of things devices, and the search for smaller more powerful chips has intensified.
