Chosun University Semiconductor Chemistry Department Succeeds in Commercializing HBM Packaging Materials
Professor Son Hongrae Leads Project with Academia-Industry Partners
Academic Achievements Stand Out, Including Publication in International Journal (IF 6.4)
The research team at the Department of Semiconductor Chemistry at Chosun University is gaining attention for achieving world-class research results in the commercial application of next-generation semiconductor packaging materials and in the field of advanced photonanomaterials, based on the convergence of semiconductor technology and chemistry.
According to Chosun University on August 12, the PNL (Photo Nanomaterials Laboratory), led by Professor Sohn Hongrae of the Department of Semiconductor Chemistry, is actively conducting research on semiconductor and optical materials, as well as chemical sensor technology, based on organosilicon polymers and photofunctional nanomaterials.
From 2022 to 2025, the laboratory successfully carried out a project titled “Technology Development for Commercialization of Bonding and Debonding Equipment and Adhesives for Ultra-Thin Wafer Handling for HBM Manufacturing,” in collaboration with industry-academia-research institutes, including SK Materials Performance.
The PNL research team, which participated in the development of temporary fixing adhesives for bonding and debonding ultra-thin wafers, made a decisive contribution by securing functional adhesive technology that can be immediately applied to the manufacturing process of HBM, the core of AI semiconductors, and by establishing the foundation for commercialization.
The team has achieved not only technical support for the industry but also significant academic accomplishments. The PNL team recently published a study titled “Thermo-Optical and Mechanical Testing of High-Refractive Index Omnidirectional Polysiloxane Hybrimers for Optical Encapsulation” in the international journal Polymer Testing (IF 6.4). According to the JIF index, this journal ranks within the top approximately 4.1% in its field globally.
In addition, the team achieved another milestone by publishing research on “real-time detection of high-performance explosive vapors such as TNT, RDX, and PETN using energy transfer and aggregation-induced emission characteristics of multicomponent silicon nanowires” in the Chemical Engineering Journal (IF 12.5, top approximately 4.0%).
