 vendors are Samsung Foundry, and United Microelectronics Corporation (“UMC”). From Samsung Foundry, we currently use 28nm mixed-signal and digital Complementary Metal-Oxide-Semiconductor (“CMOS”) production processes for 4G baseband modem, and 8nm technology for 5G baseband modem products. which are under development. The use of these commercially available standard processes enables us to produce our products more cost-effectively and, by migrating to lower process geometries, we expect to achieve advantages in cost, size and power consumption. Particularly, given the fact that foundry companies, which can provide the leading-edge foundry technology for fabless semiconductor companies to access, are very few and practically limited to TSMC and Samsung Foundry in this market, it is very important for us to establish close relationships with such foundry companies. Currently, the Company and Samsung Foundry enjoy a mutually beneficial foundry relationship providing secure access to leading-edge technology and manufacturing capacity as our 5G business ramps. From UMC, we currently use 110 RF production process for 4G RF only, and 40nm RF, mixed-signal and digital CMOS production processes for 4G baseband, 4G RF and 5G RF. From TSMC, we currently use 40nm RF, mixed-signal and digital CMOS production processes for 4G RF only. We use Hana Micron, Stats ChipPAC, and Advanced Semiconductor Engineering, Inc., (“ASE”) for most of our assembly and testing requirements on a purchase order basis. We conduct extensive simulation, practical application and standardized test bed studies to validate and verify our products. We closely monitor the production cycle from wafer to finished goods by reviewing electrical parameters, manufacturing processes and test yield data. We also run routine reliability monitoring programs to ensure long term product reliability. This enables us to operate certain test processes on demand to reduce the time-to-market for our products and to help ensure their quality and reliability. The Company and all of our outsourcing partners have implemented and adhered to the quality management system and environmental management system as required by ISO 9001:2015 across the organization. This has enabled the establishment of a robust quality assurance system for production and products, securing trust from our customers. We are also proactively responding to the strengthening of international environmental regulations and meeting market demands. Human Resources As of December 31, 2024, we had 121 full-time employees, of whom 96 were located
