Super chips are expected
Israel, known as "the silicon spring testing machine in the Middle East is mainly a machine Valley used to test the performance of springs", has developed high technology, and its chip industry and semiconductor technology are particularly eye-catching. The annual export volume created accounts for more than 20% of Israel's total Tyvek 40L, which continues many advantages of Tyvek series. At present, Israel is developing super chips that are smaller and 100 times faster than traditional chips. The prospect is full of expectations
it is reported that Uriel levy, a physicist at the Hebrew University in Israel, and his research team have been committed to developing a new chip technology. After more than three years of unremitting efforts, the research work has finally yielded results. Using the "metal oxide nitride oxide silicon" structure (MONOS), they developed a new integrated photonic circuit preparation technology, according to which flash memory technology can be used on microchips, which is expected to make smaller and faster photonic chips a reality, and its operation frequency can even reach the terahertz level, which will increase the operation speed of computers and related optical communication equipment by 100 times
the so-called terahertz (THz) is one of the frequency units. Terahertz wave contains electromagnetic wave with frequency of 0.1thz-10thz, which is an electromagnetic spectrum between microwave and infrared light bands. Compared with the development of microwave technology, people have limited understanding of terahertz band, forming the so-called terahertz gap. Terahertz wave has penetrability and less energy than X-ray, so it will not cause damage to human tissue and DNA. In recent years, terahertz technology has become a highly concerned frontier field of science and technology, and has great potential in the field of microchips
generally speaking, optical communication includes all technologies that use light as an information carrier and transmit through optical cables. For example, Internet, email, SMS, cloud and data center all belong to the category of optical communication. The speed of optical communication is extremely fast, but in microchips, optical communication has become unreliable and difficult to repeat and expand. Specifically, there are two major technical problems that hinder the development and manufacturing of terahertz microchips. One is the overheating of the chip itself, and the other is the non scalability. Scientists pointed out that the ultra-high precision and repeatable preparation of micro photonic devices is an important technical guarantee for the successful development of integrated photonic chips
Levy's scientific research team has made breakthroughs in these two problems. They skillfully bypassed the current technical problems of low micro nano processing accuracy, poor repeatability and scalability of photonic devices, introduced flash memory technology into the processing of silicon-based photonic devices, and successfully achieved the preparation of reliable and repeatable photonic devices. This measure has important foresight and pioneering significance for the advent of integrated photonic chips in the future, which is expected to trigger a revolution in the chip industry. Some analysts said that this discovery will help to fill the terahertz gap and create new and more powerful wireless devices, which can enable the chip to transmit data at a much higher speed than at present. It is a technology sufficient to change the rules of the game in the high-tech field of chips
in fact, the transformation from electronic communication to optical communication is quite attractive to chip manufacturers. Indeed, the lever swing is flexible and the friction force is small, because after breaking down technical barriers, optical communication can significantly improve the computing speed of chips and greatly reduce power consumption. People hope that terahertz microchips, which are hundreds of times faster than traditional chips, can be introduced as soon as possible to better benefit mankind
