(Press-News.org) KERI succeeded in transferring the ‘Ion Implantation and its Evaluation Technology for the SiC (silicon carbide) Power Semiconductor’ to a Hungarian company.
Power semiconductors are key components in electricity and electronics, acting as the muscles of the human body by regulating the direction of current and controlling power conversion. There are many different materials for power semiconductors. Among them, SiC is receiving the most attention due to its excellent material properties, including high durability and excellent power efficiency. When SiC power semiconductors are incorporated into electric vehicles, they cut down the power consumption of the battery and reduce the body weight and volume of the vehicle, resulting in energy efficiency improvements of up to 10%
While SiC power semiconductors have many advantages, the manufacturing process is also very challenging. Previously, a method was applied to create a device by forming an epi layer (single-crystal semiconductor thin-film) on a highly conductive wafer and flowing current through that area. However, during this process, the surface of the epi layer becomes rough and the speed of electron transfer decreases. The price of the epi wafer itself is also high, which is a major obstacle to mass production.
To solve this problem, KERI used a method of implanting ions into a semi-insulated SiC wafer without an epi layer. Ion implantation, which makes a wafer conductive, is the work that breathes life into a semiconductor.
SiC materials are hard and require very high energy ion implantation followed by high temperature heat treatment to activate the ions, making it a difficult technology to implement. However, KERI has succeeded in securing the relevant technologies based on its 10 years of experience in operating ion implantation equipment dedicated to SiC.
"Ion implantation technology can significantly reduce process costs by increasing current flow in semiconductor devices and replacing expensive epi wafers," said Dr. Kim, Hyoung Woo, Director, Advanced Semiconductor Research Center, KERI. He continued, “This is a technology that increases the price competitiveness of high-performance SiC power semiconductors and contributes greatly to mass production.”
This technology was recently transferred to ‘SEMILAB ZRT (CEO: Tibor Pavelka)’, a semiconductor metrology equipment company located in Budapest, Hungary. With a 30-year history, SEMILAB has manufacturing plants in Hungary and the United States. SEMILAB owns patents for medium-sized precision measurement equipment and material characterization equipment, and has the world's leading technology in semiconductor electrical parameter evaluation system.
They predict that through this technology transfer, they will be able to standardize high-quality SiC. SEMILAB plans to use KERI technology to develop specialized equipment to evaluate the ion implantation process of SiC power semiconductor. Park Su-yong, the president of SEMILAB Korea, said, “Through the development of specialized equipment, we will be able to progress in-line monitoring of implant processes on SiC wafers for immediate, accurate, and low-cost production control of implant systems and in-line monitoring for pre-anneal implant.” He added, “This will be a great foundation for stably securing a high-quality ion implantation mass production process with excellent uniformity and reproducibility.”
The KERI(Korea Electrotechnology Research Institute) is a government-funded research institute under the NST(National Research Council of Science & Technology) of the Ministry of Science and ICT. It has a total of more than 120 intellectual property rights in the field of power semiconductor research. As of the last 10 years, power semiconductor division of KERI has achieved more than KRW 3 billion in technology transfers, the highest level in South Korea. <KERI>

Analysis of heat exposure during pregnancy and severe maternal morbidity
2023-09-07
About The Study: Long- and short-term heat exposure during pregnancy was associated with higher risk of severe maternal morbidity in this study with 403,000 pregnancies from 2008 to 2018 in Southern California. These results might have important implications for severe maternal morbidity prevention, particularly in a changing climate.

Phase I clinical trial shows treatment designed to clear senescent cells in Alzheimer’s disease is safe
2023-09-07
WINSTON-SALEM, N.C. – Sept. 7, 2023 – Alzheimer’s disease is the most common cause of dementia that affects more than 6.5 million Americans, according to the Alzheimer’s Association. To find effective treatments and slow the progression of this debilitating disease, researchers have made much progress in developing new drugs that target beta-amyloid plaques, one of the hallmarks of Alzheimer’s disease.
Beta-amyloid plaques are accumulations of brain protein fragments, which can impact cognition. However, these recent drugs have only yielded modest results.
Now, ...
Ravenous black hole consumes three Earths’-worth of star every time it passes
2023-09-07
A star like our own Sun in a nearby galaxy is gradually being eaten away by a small but ravenous black hole, losing the equivalent mass of three Earths every time it passes close.
The discovery by University of Leicester astronomers is reported today (7 September) in Nature Astronomy and provides a ‘missing link’ in our knowledge of black holes disrupting orbiting stars. It suggests a whole menagerie of stars in the process of being consumed that still lie undiscovered.
The team was supported by the UK Space Agency and the UK Science and technology Facilities Council (STFC).
The astronomers were alerted to ...
MIT engineers design more powerful RNA vaccines
2023-09-07
CAMBRIDGE, MA -- RNA vaccines against Covid-19 have proven effective at reducing the severity of disease. However, a team of researchers at MIT is working on making them even better. By tweaking the design of the vaccines, the researchers showed that they could generate Covid-19 RNA vaccines that produce a stronger immune response, at a lower dose, in mice.
Adjuvants are molecules commonly used to increase the immune response to vaccines, but they haven’t yet been used in RNA vaccines. In this study, the MIT researchers engineered both the nanoparticles used to deliver the Covid-19 antigen, and the antigen itself, to boost the immune response, ...
Genetic tools probe microbial dark matter
2023-09-07
Patescibacteria are a group of puzzling, tiny microbes whose manner of staying alive has been difficult to fathom. Scientists can cultivate only a few types, yet these bacteria are a diverse group found in many environments.
The few types of Patescibacteria that researchers can grow in the lab reside on the cell surfaces of another, larger host microbe. Patescibacteria in general lack the genes required to make many molecules necessary for life, such as the amino acids that make up proteins, the fatty acids that form membranes, and the nucleotides in DNA. This has led researchers ...
Revolutionizing lithium production on a string
2023-09-07
A vital component of the batteries at the heart of electric vehicles and grid energy storage, lithium is key to a clean energy future. But producing the silvery-white metal comes with significant environmental costs. Among them is the vast amount of land and time needed to extract lithium from briny water, with large operations running into the dozens of square miles and often requiring over a year to begin production.
Now, researchers at Princeton have developed an extraction technique that slashes the amount of land and time needed for lithium production. The researchers say their system ...
