According to a report from the BBC on April 22, Intel introduced the Ivy Bridge series of processors built with 22-nm 3D transistors to increase computing power and reduce energy consumption.
Kirk Sjögen, director of Intel’s personal computer business, said: "The impact of this system design is quite alarming. There are more than 300 mobile product developments and more than 270 different workstations, many of which are Integrated design. This is the first product in the world to use 22nm 3D transistors."
Sikangen explained that conventional transistors use "planar" two-dimensional gates that open and close as fast as possible, and that they can pass the maximum current when they are turned on, and the current that passes when they are turned off is the smallest. But the problem is that if the speed of opening and closing is not balanced, the smaller the plane gate is, the more energy will leak.
The transistor of the ivy bridge chip is only 22 nanometers long, which means that it can put 4,000 on the width of a human hair. Intel's solution is to replace the planar gate with a three-dimensional ultrathin fin transistor, so that the "lying" drain and source of the transistor "stands" on the silicon substrate. The three gates are wound. Together, one on each side plus one above. So when the gate opens and closes more than 100 billion times per second, the leakage rate drops to near zero, thereby performing the same previous operation with less power.
This innovative chip breaks through the bottleneck that transistors tend to be miniaturized and has limited performance. It not only solves the manufacturing problem, but also brings fairly good performance. For example, it can be driven with a lower voltage, the leakage current is drastically reduced, and the transistor can withstand The upper current limit is higher, and its manufacturing cost has only increased by 2% to 3%.
Scottone said that these chips take an integrated GPU (Graphics Processing Unit) instead of a discrete graphics card, and the processing speed is significantly increased, and will be able to handle high-definition video conferencing. Users can also recode video more quickly to send video clips by e-mail or save it to a smartphone. The chip also offers new hardware-based security features, as well as built-in support for USB 3.0, making it cheaper and providing manufacturers with the standard to allow faster data transfer to hard drives, cameras, and other peripherals.
At present, Intel has established three factories to manufacture this new type of chip, which will be sold online in the fourth quarter of this year. (Hua Ling)
