Magnets, Germanium May Allow Chipmakers to Move Beyond 22nm

Maximum PC Staff

While it’s presently believed that 22nm will be the maximum achievable process shrink using silicon, recent discoveries might allow chip makers to cut the 2020 goal set by Moore’s Law loose.

The discoveries come in the form of a manganese-doped germanium substrate, which will allow the creation of nanowires that can be easily magnetized. The magnetizing effect is reportedly showing “the potential of using these nanowires as building blocks for electronic devices,” such as “ferromagnetism above 300 K and a superior performance with respect to the hole mobility of around 340 cm2/Vs and other industrially relevant parameters.”

So what does all this mumbo-jumbo mean? Well, in short there’s a chemical element (number 32 on the periodic table, if you’ve got one handy) that, when mixed with a magnetic field, is showing some promise for chipmakers looking to break the 22nm barrier. With any luck, in the 10 years between today and the marked date for the 22nm barricade, the research will come full circle.
