Samsung breaks ground on $4.5 B high‑bandwidth memory packaging plant in South Korea

Samsung Electronics announced the start of construction on a high‑bandwidth memory (HBM) packaging facility at its Onyang campus in Asan. The project involves a ₩6 trillion ($4.48 billion) construction spend and a total planned investment of ₩46 trillion (about $34 billion) for equipment and build‑out. The plant, covering roughly 31,000 m² of clean‑room space, is slated to begin operations in June 2028, a year earlier than previously expected.

The company says the new line will expand its HBM packaging capacity, but because it will not be operational until 2028 it will not ease the current memory shortage. The large equipment spend benefits semiconductor‑equipment suppliers that provide the specialized tools for HBM stacking and bonding.

  • 1Construction investment is ₩6 trillion ($4.48 billion).
  • 2Total planned HBM packaging investment is ₩46 trillion (approximately $34 billion).
