4^th International Conference on Semiconductor Materials and Technology (4^th ICoSeMT 2025) is a biennial event that is jointly organized by Institute of Nano Optoelectronics Research and Technology (INOR), Universiti Sains Malaysia (USM), Universiti Teknologi MARA Cawangan Pulau Pinang (UiTMCPP),  National Nanotechnology Centre (NNC), Ministry of Science, Technology and Innovation of Malaysia (MOSTI), MIMOS Berhad and Collaborative Research in Engineering, Science & Technology (CREST) with the Theme “Innovation Towards A Sustainable Tomorrow”. The primary focus of the conference is to create an effective medium for institutions and industries to share ideas, knowledge, and expertise in the fields related to Semiconductor Materials and Technology.

This year, with the aim to promote positive innovation culture and encourage innovation activities and from different walks of life, a sub-event entitled International Invention, Innovation & Design Expo (INoDEx 2025) is going to be held concurrently. This sub-event will be a great platform in creating opportunities for local and international participants to present their innovations and inventions. Eventually, both events will lead to interaction and future collaboration among the local and international participants.
