Semiconductor measurement is considered as an area where ultra-precise science of measurement is concentrated, surpassing precision due to complex five senses. Like OLED displays or solar batteries, McScience boasts Korea’s best measurement technology in semiconductor field. With reliable measuring equipment and systems, it is expanding its scope to small but strong companies.

McScience (CEO Yoon Cheol-oh) develops and supplies measurement equipment to evaluate various performance of displays, semiconductors and energy devices that have electrical and optical characteristics. Relevant measurement components include voltmeter, ammeter, source meter, waveform generator, and photometer measuring devices such as spectrometer and luminometer. By combining these measurement components, Samsung Electronics is constructing a system that evaluates characteristics of high-tech devices such as OLED, organic semiconductors, solar energy, lithium-ion batteries, and microLEDs and supplies them with professional measurement software. In order to understand the excellence of McScience’s measurement technology, it is necessary to understand the concept of OLED (Organic Light Emitting Diodes). OLED display is a device that outputs light as electricity is inputted. Therefore, in order to measure and evaluate performance of OLED displays, characteristics and efficiency of process of converting energy from electricity to light are essential. That’s exactly what McScience is in charge of. OLED that is evolved from LED is fundamentally different in that it has ‘O’, which means organic water. In other words, while LEDs consist of minerals, which are silicon and similar elements, OLED is composed of organic materials like plastic. This is the key to understanding the importance of developing ‘OLED life measurement equipment’ that McScience has localized, Yoon said. “OLEDs are organic, so they can flexibly and synthesize them to create a greater variety of colors and luminance. However, the problem of metamorphosis, which is considered to be a disadvantage of organic materials, was a task that had to be overcome during early development of OLED displays. OLED life measurement equipment that verifies this.” Actually McScience’s ‘OLED life measurement equipment’ has been supplied to OLED display manufacturers since the early 2000s when OLED devices appeared in markets. It is also used by many OLED businesses and research institutes in global markets, so it can check McScience’s technical skills.

CEO Yoon Chul-oh stressed that various small and medium measurement companies in Korea need to cooperate with each other and jointly respond to global competition by combining products.

Development of electronic measurement components, systems, and software

If an OLED display is a semiconductor in which light is output due to electricity input, a solar cell is a semiconductor in which light is inputted and output as electricity. Therefore, McScience’s measurement equipment that measures solar cells is a necessary inspection equipment for measuring characteristics and efficiency in the process of converting energy from light to electricity. McScience has increased accuracy in measuring solar cell performance by applying solar-powered solar-simulating solar-powered solar system. In particular, in the field of electronic instrumentation, precision requires specialized skills to overcome limiting factors, such as power device stability and digital interface resolution. To this end, McScience used a patented technology called DC Candling to accurately measure 5V voltages up to 6 digits below the decimal point with 1uV resolution. In particular, the imaging system of solar cells is an equipment that can verify McScience’s outstanding technology for measuring solar cells. It is an equipment that detects visible internal defects through infrared image images using semiconductor characteristics of solar cells and is currently used as a necessary inspection equipment for mass-production process of solar power modules. McScience also developed an internal resistance measurement system for secondary batteries and prepared a measurement technology that can be used to evaluate characteristics of batteries for electric vehicles that combine large amounts of single batteries directly and in parallel. Yoon also announced that he is preparing to develop various measuring equipment and technologies. “The field of measurement is very broad and applies to a wide variety of factors and technologies depending on what we measure. We have modularized about 50 measurement technologies in the fields of electronics, optics, vision testing, temperature control, and measurement automation, and combined measurement modules for measurement purposes to implement an optimal professional measurement system for evaluation of displays, semiconductors and energy devices. We have developed 46 standard measurement recipes for OLED, solar and secondary battery characteristics.”

The measurement equipment of McScience that assesses the performance of solar cells measures the characteristics and efficiency of solar cells in the process of converting energy from light to electricity.

Create automotive, robot, bio and medical industrial technologies

As such, McScience also has a number of hardware and software-related instrumentation modules that evaluate important characteristics of various high-tech devices. In addition, individual equipment is operated in an integrated manner by combining it with IoT technology.

It also plans to systematically accumulate data from measurement results and eventually develop it into a big data system that can understand the correlation between data. This is because McScience can emerge as a key technology that will lead the fourth industrial era if it improves performance of related inspection equipment such as applying Mchine learning to its video processing technology. If it is connected to major technologies of 4th industries such as IoT, Mchine Vision, Mchine Learning, and Big Titer, it can expand to major industries that future information society requires. However, it is regrettable that related measurement companies in the same industry exist in the form of small, multi-products led by many small and medium sized companies rather than large ones, Yoon said. This means that the domestic market alone is very difficult to grow. To compete with global operators, we need to work together, integrate products, share knowledge and experience, and standardize parts to jointly respond to global competition, Yoon said, stressing the support of the government and related agencies.
