IBM

IBM has engineered up a new pilot line for making chips.

The gates are just 7nm wide and 30nm apart.

Which allows them to make processors with 22 billion transistors.

At 7nm this means the gate is about 14 atoms wide.

In silicon this number of atoms just couldn’t carry enough current for the rest of the chip to function properly so they have moved to Silicon Germanium wafers.

For those of us that have done R&D in wafer fabs this is beyond belief. Really!
