Beijing time on July 17th news, a South Korean research team has successfully achieved a more energy-efficient ternary metal oxide semiconductor on large-size wafers.

Kyung Rok Kim, a professor in the Department of Electronic and computer Engineering at Ulshan University of Science and Technology in Korea, and his team have successfully developed a semiconductor that operates on a ternary logic system rather than an existing binary logic system. The study was published in Natural Electronics.

The research team said that the use of a ternary system consisting of 0, 1, 2 reduces the amount of information that semiconductors need to process.Improve information processing speed and thus reduce energy consumption. It also helps to further reduce the chip size.

For example, using a binary representation of the number 128 requires 8 "bits" of data; with ternary, only 5 "bits" of data are required.

Current leakage is a major obstacle to further reducing chip size. Encapsulating more circuits in a smaller space can make tunneling more serious, increasing the leakage current, which means that the device consumes more power.

Kyung Rok Kim said that if this semiconductor technology is commercialized, it will not only mark a fundamental change in the chip industry, but also positively affect industries that rely heavily on semiconductors such as artificial intelligence, driverless cars, Internet of things, biochips and robots. influences.

Since September 2017, Samsung has been funding Kyung Rok Kim's research through the Samsung Science and Technology Foundation. The Samsung Science and Technology Foundation supports promising technology projects.

Samsung has already validated this technology in the chip foundry business unit.
