Samsung Electronics

Samsung Electronics commands the top spot as the world’s largest manufacturer of smartphones, memory chips, and OLED displays, with its semiconductor division alone contributing over 20% of South Korea’s total export revenue. The Suwon and Hwaseong chip fabs are among the most advanced semiconductor manufacturing facilities ever built, producing cutting-edge 3nm process nodes that outperform #2 LG Electronics in fabrication scale and efficiency. Samsung generates approximately $200 billion in annual revenue, over 50% more than its nearest domestic rival.
