South Korean giants Samsung and SK hynix have announced plans to invest about 1,350 trillion won, roughly $870 billion at the time of writing, into expanding semiconductor manufacturing capacity and data centers over the next ten years. This ten-year plan includes memory, storage, and logic, which both companies produce. For SK hynix, this investment will cover DRAM and NAND Flash, while for Samsung, it will cover DRAM, NAND Flash, as well as logic for its LSI division. The investment is so comprehensive that it will include more than just creating new fab production capacity for increased wafer output. For example, it will also encompass AI data centers, batteries, display manufacturing, chip-making tools, etching, photomasks, and much more.
