. . . 20 nm may represent an inflection point in which it will be necessary to transition from a metal-oxide semiconductor field-effect transistor MOSFET to Fin-Shaped Field Effect Transistors FinFET or 3D transistors, which Intel refers to as tri-gate designs that are set to debut with the companys 22 nm Ivy Bridge product generation.
Three Dimensional transistors in the news again. Previously Intel announced they were adopting a new design for their next generation next smaller design rule for the Ivy Bridge generation Intel CPUs. Now ARM is also doing work to integrate similar technology into their ARM cpu cores as well. No doubt in order to lower Thermal Design Point and maintain clock speed as well are both driving this move to refine and narrow the design rules for the ARM architecture. Knowing Intel is still the top research and development outfit for silicon semi-conductors would give pause to anyone directly competing with them, but ARM is king of the low power semi-conductor and keeping pace with Intel’s design rules is an absolute necessity.
I don’t know how quickly ARM is going to be able to get a licensee to jump onboard and adopt the new design. Hopefully a large operation like Samsung can take this on and get the chip into it’s design, development, production lines at a chip fabrication facility as soon as possible. Likewise other contract manufacturers like Taiwan Semiconductor Manufacturing Company (TSMC) should also try to get this chip into their facilities quickly too. That way the cell-phone and tablet markets can benefit too as they use a lot of ARM licensed cpu cores and similar intellectual property in their shipping products. And my interest is not so much invested in the competition between Intel and ARM for low power computing but more the overall performance of any single ARM design once it’s been in production for a while and optimized the way Apple designs its custom CPUs using ARM licensed cpu cores. The single most outstanding achievement of Apple in their design and production of the iPad is the battery charge duration of 10 hours. Which to date, is an achievement that has not been beaten, even by other manufacturers and products who also license ARM intellectual property. So if the ARM design is good and can be validated and proto-typed with useful yields quickly, Apple will no doubt be the first to benefit, and by way of Apple so will the consumer (hopefully).
