3D transistors from Intel
Since 2002, Intel has been working on a new type of transistor. Its “three-dimensional” design would allow to overcome the limitations of silicon structures.
Restrictions for many seemed to be insurmountable. Many times in a history there were voices that we are approaching the impassable border. The material had reached its limits. Salvation could be a complete change of technology, support building transistors on something other than silicon. However, also as usual, an attempt was made to circumvent this problem. Thus, the idea ofconstructing a 3D transistors was born.
Over that Intel has worked since 2002. Traditional chips currently used include flat gate, with two “sides” of flow. Three-dimensional gates are wrapped so that they are above the silicon plane and have three “sides”. Thanks to this, energy flow is much faster when the processor is running. In turn, when it is turned off, much smaller energy losses are recorded than in previous designs. What’s more, it can quickly move from one state to another. In practice, this means that Intel will be more efficient and will consume less electricity. The enthusiasm of company is big - a new technology is supposed to allow to continue realization of the Moore law, under which the processing power doubles every 24 months
Three-dimensional transistors reach almost 40% more power than the 32nm chips built with flat wickets. On the other hand, when working with the same efficiency, half better balance of energy intake can be achieved. What is interesting and at the same time very optimistic, is that the cost of production of new components will be only 2-3% higher. Such an increase would be almost imperceptible, which together with the benefits of technology sounds very interesting. Many people believe that Intel's technology will bring huge benefits not only for manufacturers of computers, but also for all sorts of mobile devices.
Intel has already introduced the first processor built in 3D technology. It is called Ivy Bridge and is made in 22nm technology.
