Jeong Se-young, CTO of CIT | Photo by AVING NewsAs high-resolution content, virtual reality (VR), augmented reality (AR), autonomous driving, and the Internet of Things (IoT) services dealing with vast amounts of data continue to grow, data production and consumption have surged. To share or transmit this data, high-frequency waves are used. High-frequency waves have short wavelengths, allowing them to transfer massive data quickly. This is why 5th generation (5G) communication uses the 28GHz high-frequency band.
However, the right equipment and materials are necessary to utilize high-frequency waves properly. This is because they are sensitive to obstacles. Let's take water as an example. When water flows through a pipe at low speeds, it is not significantly affected by protrusions or pipe thickness. But when it flows at high rates, its velocity decreases depending on the pipe's thickness or obstacles. High-frequency waves are similar. If there are obstacles, they do not propagate properly or suffer losses.
To address these issues, a South Korean startup, Copper Innovation Technologies (CIT), has developed the next-generation flexible copper-clad laminated film (FCCL) based on materials that reduce signal loss in high-frequency waves and enable fast transmission. AVING News's Jay had a special interview with Jeong Se-young, CTO of CIT, to learn more about this development. The interview script is revised for the best readability while maintaining the original meanings.
Reporter Jay from AVING News interviewing Jeong Se-young, CTO of CIT | Photo by AVING NewsQ. Hello, everyone, I’m Jay with AVING News, and today I am with Dr. Jeong, the CTO of CIT. Dr. Jeong, how are you? Nice to meet you. Can you tell me about your company and what you are working on?
A. I have been working pretty long with copper. My original major was dielectric materials and magnetic material, but from a certain point, I started to study copper because copper is a beautiful material. Copper is a widespread material that everybody knows, but if you make it in a single crystal, then the property of the material changes a lot—single crystal. So, maybe it sounds weird that it becomes a single crystal. Usually, people believe that single crystals look like a gem or diamond. Yeah, that is what people typically imagine, but a single crystal means that the atoms are aligned perfectly in one direction, called a crystal. So, we deposit on sapphire or MgO (Magnesium Oxide) or use silicone as a substrate, and then the film’s structure follows from the substrate. It is tough to control, but our new technology is to develop that single crystal structure from the substrate without influencing the substrate structure.
Metal materials for CIT's products | Photo by CITQ. Is your company based out of Korea?
A. Yeah, yeah. We will establish our workstation this February in Busan, but we plan to extend it more broadly to go international.
Q. So it’s first starting domestically, with the hopes and goals of going international. 3:31 When was your company founded?
A. This year, in March. I have been studying copper for quite a long time, but our company was started this past March.
Q. What inspired you to start your company?
A. I had a friend working in a Teflon company, and then he asked me to deposit copper on Teflon. People always needed to do this, depositing copper on Teflon. Still, we succeeded because we developed a new method to deposit copper on various substrates. After finding it an exceptional technology, we discussed collaborating and opened a new company.
Wire terminals made by CIT | Photo by CITQ. Can you talk about your essential products and technologies? What makes CIT so unique?
A. We can make single crystal cables made of single crystal wire, which can transfer signals without noise. So, grain boundaries scattering over electrons make noise, which people ignored because people had no idea about that. Still, now we understand what happens with single crystals. We will do everything with single crystals in our business.
However, the first topic is whether we can produce the electronic circuit deposited on Teflon. Then, it can be used for flexible PCB boards and flexible FCCL (flexible copper-clad laminate). So, it will be used for flexible PCB, then placed in an iPhone or Galaxy PCB board to be flexible. It has a very low dielectric constant and dielectric loss, allowing the signal to be transferred natively. Therefore, we save power and information. Consequently, we have advantages for that.
Q. Do you see this only applies to phones or various applications? For example, you talked about Galaxy phones, but this flexible PCB board can be used in multiple applications, correct? Anything that requires a flexible PCB board?
A. Yeah, in audio devices or many measurement systems, and if you have extensive facilities, like MRI or other SAM and observation systems, you can apply everywhere. It is flexible to save space in that pattern or design. So it is an advantage.

A. We published a paper in Nature (science journal) regarding this technique. This technology was introduced, and usually, if you deposit a film on different substrates during the sputtering process, people prefer to use MB, PLD, or other costly facilities, but the sputtering system is the cheapest. However, the advantage is that we can deposit it at a wafer scale. We can make larger-scale deposition possible.
So, in this case, the problem was that we had a lot of atoms as a cluster during the sputtering process. Hence, the group comes to the substrate and is deposited arbitrarily, causing the overall adhesion to be very bad. Therefore, it is separated easily. However, if we deposit, at the deposition process, we reduce all noise that can occur during the sputtering process. We eliminated the possibility because we deposit atom by atom one by one. So, it sounds simple, but usually, it is more complicated with that technology. But with 20 years of experience with this technology, we developed a way to deposit atom by atom, allowing particles to go everywhere and adhere to any substrate.
Q. So, who are your target market and potential buyers for this?
A. I oversee the technical part. Therefore, our CEO will do much better than me, but as far as I know, we want to collaborate with some first band companies, so we are working with Samsung and other technology companies. So, the flexible PCB board can be used for iPhone and Galaxy phones, firstly.
Also, in computers, as a flexible PCB board, as well as curved TVs, in this case, it can be applied. In other instances, audio systems are used for medical purposes or in many facilities like MRIs. Specifically for medical purposes, using a single crystal wire as a reactor can improve the signal very well. The medical alert is minimal; if you amplify it, the noise signal at high frequencies becomes much larger than the signal itself.

It basically will replace anything, up until this point, that uses a flexible PCB in any application. This technology can replace it. The higher conductivity, no noise, or reduced noise, anything from our consumer electronics, the public is most interested in going in their cellphones because it’s public. Still, you’re thinking it is more significant than this. Going into medical devices, for example, audio devices, would be great, but medical devices, really helping people with this technology, is your big personal goal, correct?
A. At this moment, we are starting with the target of the electronic circuit using Teflon, but of course, my goal for the future is to extend it to many different areas.
Q. What are your goals for the end of this year?
A. So, this kind of sample, at the size of this scale, 3”, 4”, 5”, is limited in scope because we are working in a laboratory. However, after starting the company, we want to enlarge the size of the product. Therefore, we already ordered a large-scale system, making producing a 50cm x 50cm size deposition possible. Then, when we succeed, we can directly apply this to many cases. So mass production is possible.
Cables made by CIT | Photo by CITQ. Do you have a goal for next year per se? Or do you see the goal at the end of this year and then three years later? What are you considering as a short-term, mid-term, or long-term span? Do you want to start rolling out the product by next year? Is that the goal?
A. Next year we will likely succeed in fabricating our new product next year. And then, after three years, we can extend it to many different areas. Then, the final goal of mine is that all single crystal material we wish to apply to audio systems, MRI, and everywhere. So this is the reason why I am going to Boston next year. I am collaborating with people at Harvard Medical School in the medical imaging department. We decided to collaborate. I just learned that medical school people are working with copper. They said they use copper more than I do. More than us! They need high-quality conductive metals because they work in medical imaging. Therefore, it is a very educated choice.
Q. And you have the highest quality conducting method now.
A. Thank you. I appreciate your kindness. And again, this is Jay with AVING News. We are here with Professor Jeong, who explained the new technology he’s working on. He is the CTO of CIT. Thank you again so much for your time. I appreciate it, and we’ll join you guys next time for another interview. Thank you so much. Thank you for your time.
