A stark polarization deepens in the Korean labor market. Manufacturing employment in South Korea declined by 140,000 in May from a year earlier, marking the steepest drop in over seven years and the 23rd consecutive month of decline. Conversely, propelled by an AI-driven memory super cycle, the semiconductor industry anticipates a 2.8% employment expansion in the first half of 2026, emerging as the sole clear job growth engine among Korea’s ten major manufacturing sectors. This divergence reveals a palpable ‘semiconductor bias’ within the nation’s job landscape.
SK Hynix has strategically positioned itself at the forefront of this super cycle through early and sustained investment in High Bandwidth Memory (HBM) technology. The company reportedly holds a dominant share of the HBM market, with figures around 62% in Q2 2025 and 58% in Q1 2026. This leadership stems from its pioneering role in HBM development, coupled with robust partnerships with major AI chipmakers like Nvidia and foundry giants such as TSMC.
SK Hynix’s aggressive investment plans further solidify its strategic advantage. The company is investing approximately $13 billion in expanding its advanced packaging facilities in South Korea, with new plants expected to commence operations by the end of 2027. Furthermore, a $3.9 billion advanced packaging plant in Indiana, US, is slated for completion by 2028, signaling a global expansion of its manufacturing footprint. These investments aim to triple its total wafer capacity by 2034, targeting about 1 million monthly DRAM units by 2030.
The fierce competition in the HBM market is evident as rivals like Samsung Electronics and Micron Technology intensify their efforts. Samsung, for instance, is aggressively expanding its HBM back-end processing capacity and expects to increase its market share, particularly as HBM4 enters full-scale supply in 2026. Micron is also shipping HBM4 samples and anticipates selling out its HBM production capacity for 2026.
This intense focus on high-value memory has profound implications for the Korean labor market. While semiconductor exports surge—up 205.8% in the first ten days of June alone—the sector’s capital-intensive nature limits its direct employment-generating capacity. Semiconductors create only about 2.0 jobs per billion won of output, significantly less than the 4.3 jobs generated by the automobile industry. Only about 1.5% of South Korea’s workforce is directly tied to the semiconductor industry.
The ‘Samjeon-nix’ phenomenon, where jobs at leading chipmakers like SK Hynix and Samsung Electronics are viewed as highly prestigious, reflects this bias. High salaries, significant bonuses, and job stability in these firms sharply contrast with the broader manufacturing sector, where employment has been consistently declining. This creates a ‘K-shaped’ recovery, where the IT and semiconductor sectors thrive while other traditional industries face stagnation or decline, distorting the overall employment structure. Youth employment, in particular, has deteriorated, with a 255,000 decline in May from a year earlier, the largest drop since January 2021. This is partly due to companies preferring experienced hires and reduced overall new hiring, even as the semiconductor sector demands specialized talent.
Policymakers must address the widening gap in the labor market. Strategies should focus on diversifying industrial growth beyond memory chips, investing in vocational training programs to re-skill the workforce for emerging high-tech sectors, and supporting traditional manufacturing to prevent further job erosion. For investors, the sustained AI-driven demand for memory chips presents a clear opportunity, but the long-term sustainability of this ‘semiconductor bias’ warrants careful consideration of broader economic impacts and potential policy responses. Monitoring government initiatives to rebalance the industrial structure and labor market will be crucial.
