Finally successfully developed the chipset which operates at clock frequency 1 THz

The conventional record was repainted large,1 terahertz(1 THz = 1000 GHz) has been successfully developed, it was announced that it was certified as a world record in the Guinness Book of Records.

Operating frequency1.03 THzIt was the Department of Defense's Department of Agency that developed a chip that operates at ultra-high speedDARPA(National Defense Advanced Research Projects Bureau), this is a numerical value that exceeds 850 GHz (0.85 THz) which is a conventional record at a stretch.

Speaking of the evolution of chipset, it is often thought of as realizing ultra-high speed computing as typified by supercomputer, but DARPA has been promoting the development of extremely short wavelength radio waves (millimeter waves ). The use of millimeter waves realizes the merit of improving the resolution of radar used for military use and dramatically increasing the amount of data to be transmitted on radio waves, You can check the whole body in detail using the introduced millimeter wavesMillimeter wave scannerIt is thought that it will be possible to improve the performance such as radio communication at a speed far beyond the current mainstream 2.4 GHz / 5 GHz radio wave Wi - Fi communication.

When the operating frequency reaches 1 THz, switching ON / OFF of the switch by 1 trillion times in just 1 second, this is obviously impossible with the simple method "just increase the clock frequency and turn it" . The technology developed by DARPA is not yet clearly understood yet, but here we developed it jointly with Northrop GrummanCMOSProcess was usedMonolithicIt seems that chips are loaded, and it is easier to realize high speed and higher output than chip using silicon or gallium for manufacturing chipsIndium phosphideIt is thought that breakthrough technology from the material level, such as using a wafer using the material, has been introduced.

The following image is a drawing of the element that operates at 850 GHz where recording was broken. Elements that realized this time beyond 1 THz are expected to have the same structure.


In the image showing Guinness record renewal, a structure diagram that seems to point to a part of a new element is described, but this time it can be confirmed that this is the limit level.


It is a chip that achieves a speed that is nearly 1000 times faster than the current common sense, but it is too early to expect that the speed of PCs used by ordinary users will improve. This time it is a breakthrough in the element that transmits radio waves, and in order to improve the overall speed, more technical development is required. Furthermore, although it is thought that it is necessary to clear supply electricity problems and measures against heat generation, it is also a fact that it seems that a certain route has been seen in future evolution. It seems that the evolution of the chipset will continue still in the future.
