In recent years, "STEAM education" has rapidly spread in educational settings, increasing the importance of experimental environments and measurement technologies for experiential learning in science and technology. Among these, spectroscopic techniques that analyze substances and environments using light have gained attention. Not only in cutting-edge research fields such as spectroscopic measurement, laser experiments, and biosensing, but also in universities, technical colleges, and high schools, there has been an increase in experiments utilizing optical technologies. The foundation of these technologies is optical thin films (optical filters) that control the wavelength of light. Optical thin films significantly improve the accuracy of spectroscopic measurements and optical sensing by allowing only specific wavelengths to pass through or by blocking unwanted light. Furthermore, they hold potential as educational materials that enable intuitive understanding of the physics of light through phenomena such as interference and structural colors. 1.

In the medical and healthcare fields, light has already become an indispensable infrastructure. From endoscopes, fluorescence observation devices, blood analyzers, pulse oximeters, and wearable vital sensors to regenerative medicine and phototherapy devices, optical control technologies such as "wavelength selection," "reflection control," "stray light suppression," and "high-sensitivity detection" are required in every scenario. However, in actual design settings, it cannot be said that there are many cases where equipment manufacturers and optical thin film manufacturers engage in sufficient discussions from the early stages. As a result, filters and mirrors are often "added later" in the optical system's post-processing, leaving room for improvements in S/N ratio, miniaturization, and low power consumption that should have originally been achieved. We will redefine the role of optical thin films in the medical and healthcare fields and explore the possibilities from the perspective of "functional co-creation" rather than just "material supply." 1.

In the development of coating materials for semiconductors and functional chemicals, the evaluation of resistance to electromigration and ion migration has become an unavoidable and important theme. On the other hand, migration is not a phenomenon that can be simply determined by material properties alone. The differences in insulating films, protective films, and coating materials interact with wiring materials and current conditions in ways such as hygroscopicity, ion residue, barrier properties, dielectric characteristics, film thickness, film density, and interfacial adhesion, ultimately manifesting as wiring degradation or insulation breakdown. However, in actual evaluation settings: ◆ The wiring structure and material conditions differ with each evaluation. ◆ The effects of materials and structural factors cannot be separated. ◆ Reproducibility and comparability of evaluation results are difficult to achieve.

Electrochemical analysis chips are devices that utilize electrical signals such as voltage and current to read chemical reactions. The chip is equipped with working electrodes, counter electrodes, and reference electrodes, allowing for the highly sensitive detection of redox reactions occurring in solution. In recent years, compact devices combining microfluidic technology and MEMS technology have become widespread, rapidly expanding their use in medical POCT (Point of Care Testing), environmental monitoring, food testing, and life sciences. In these applications, there is a demand for higher sensitivity, miniaturization, multiplexing, and speed of detection, and essential to achieving this are the miniaturization of electrode structures and the formation of high-quality metal thin films, namely thin film metallization technology. ◆ Key to electrochemical analysis: The quality of data is determined by the performance of the electrodes ◆ Thus, "thin film metallization" is necessary ◆ Technical points when performing thin film metallization ◆ Examples of performance improvements brought by thin film metallization ◆ Future trends: Demand accelerating with POCT and wearables ◆ The inseparable relationship between electrochemical analysis chips and thin film technology For more details, please check our company website.
