In the previous video, I introduced Generative AI, one of Gartner’s 2022 strategic technologies. In this episode, let’s talk about the latest developments in Terahertz technology, which is widely considered to be one of the top 10 technologies that will change the future of the world.
Terahertz (THz) is a unit of measurement of frequency equal to 1 trillion hertz (1012 Hz). It usually refers to the frequency of electromagnetic waves, which are part of the electromagnetic spectrum invisible to the naked eye and lie between the microwave and infrared ranges.
Terahertz technology is not new. It has been studied since the 1950s, but in the past it had different names-near millimeter, sub millimeter, and extreme infrared. The development of terahertz technology relies heavily on advances in radio astronomy and space science. For example, The Atacama large-scale millimeter/submillimeter array in Chile uses terahertz technology.
In the 1970s, space scientists began to use far-infrared and submillimeter wave spectrometers to investigate the chemical composition of interstellar media and planetary atmospheres.
The Herschel Space Observatory, built and operated by the European Space Agency, which began operations in 2009, carries the world’s largest infrared telescope in history, also utilizing terahertz technology.
Terahertz waves are non-ionizing and non-invasive. Due to its low energy characteristics, terahertz radiation is harmless to humans and animals. And it can penetrate many materials. Even if a person is wearing clothes, the clothes are transparent to terahertz, just like the king in “The Emperor’s New Clothes”.
Terahertz is a kind of electromagnetic wave that exists in the natural world. The human body generates this electromagnetic wave all the time and emits and spreads outward. Therefore, the use of terahertz sensors can detect guns, knives and other “opaque” objects that are not visible to the naked eye, which means that the exact location of the hidden objects can be known without body search.
Terahertz radiation also tends to be very sensitive to a variety of resonances, such as vibrations, translations, rotations, torsions and conformational states, allowing it to provide molecular information that other analysis and imaging techniques cannot obtain. These unique characteristics make it suitable for identifying, analyzing or imaging various materials.
Terahertz (THz) technology is widely used in laboratory research, healthcare, military and homeland security, and industrial non-destructive testing (NDT). The report data shows that in 2021, the laboratory research field will account for 53.11% of the market demand for terahertz (THz) technology.
Terahertz (THz) technology applications are divided into three categories: terahertz imaging, terahertz spectroscopy and terahertz communication systems. Terahertz imaging holds an important position in terahertz technology with a market share of nearly 64.85% in 2021.
The global terahertz (THz) technology market is valued at US$318.6 million in 2021 and is expected to reach US$906.2 million by the end of 2024, with a compound annual growth rate of 23.3% from 2021 to 2024.
Today, I will introduce the world’s leading company that focuses on the application of terahertz technology-TeraView. TeraView is headquartered in Cambridge, England. It was separated from Toshiba Cambridge Research Laboratory sponsored by Toshiba Corporation in April 2001.
TeraView commercialized a revolutionary new spectral imaging method based on terahertz technology. Sales and support are available in Europe, North America and the Far East, either directly or through a network of distributors.
One of the standards in the semiconductor packaging industry is benchmarked against one of TeraView’s products. This product is the Electro Optical Terahertz Pulse Reflectometry (EOTPR), which is touted as the world’s fastest and most accurate fault isolation system.
This product was developed in cooperation with Intel and TeraView, with a fault isolation accuracy of 5 microns, and was launched in 2010. It has been accepted by the semiconductor packaging industry as the de facto standard for isolating faults in advanced IC (integrated circuit ) packaging. TeraView has delivered many systems to major semiconductor and OSAT (Outsourced Semiconductor Assembly and Test) companies worldwide.
TeraView recently announced an agreement with ACE Solution, a Taiwan-based distributor with one of the world’s leading independent failure analysis laboratories. This is the first time the company has sold EOTPR technology to an independent lab.
TeraView has other products, and there are also some noteworthy terahertz technology application companies around the world, which I will introduce later when we have a chance.
