On Monday, semiconductor equipment stocks in the U.S. market experienced gains. Applied Materials (AMAT.US) surged nearly 10%, reaching a new all-time high, bringing its monthly increase to over 50%. KLA-Tencor (KLAC.US) rose more than 7%, and Lam Research (LRCX.US) advanced nearly 6%.

The positive movement follows an announcement by the South Korean government on Monday detailing its largest-ever investment plan for the semiconductor and artificial intelligence sectors. President Lee Myung-bak presided over the launch event for the "Three Major Super Projects," revealing plans to invest approximately 800 trillion won in building four semiconductor fabrication plants in the southwestern region. Samsung Electronics will construct two of the plants, with the remaining two built by other contractors, aiming to double DRAM production capacity within five years.

The massive capital expenditure required for this expansion will inevitably begin with the procurement of equipment to establish production lines. Both the "front-end equipment" used in wafer manufacturing and the "back-end equipment" critical to the performance of AI chips are poised to benefit. Global leading equipment manufacturers are expected to directly benefit from this wave of capacity expansion.
