TSMC claims 40 nanometre breakthrough

TAIWANESE FOUNDRY TSMC said it’s tweaked its 45 nanometre process technology to 40 nanometres. It has shown off general purpose and a power efficient versions of the technology.

The firm said the 40 nanometre process will produce the smallest SRAM cell size in the industry, with the chips incorporating active power down scaling of a claimed 15 per cent over its current 45 nanometre tech.

The low power version will be used in what TSMC terms “leakage sensitive” apps including wireless and portable devices, while the 40G version will be used for CPUs, graphics processors, and games consoltes. The chips will be fabbed up at TSMC’s 12-inch factories.
