中东战火下，半导体供应链受阻

Core Viewpoint - The semiconductor industry is facing significant procurement and cost pressures for key materials due to geopolitical tensions, particularly the conflict between the US and Iran, which has raised concerns about supply disruptions and price volatility [4][5]. Group 1: Supply Chain Concerns - Korean chip manufacturers are closely monitoring the situation, fearing that supply interruptions could affect critical raw materials such as helium, diluents, ethanol, and isopropyl alcohol (IPA) [5]. - Helium prices have surged over 50% recently, prompting manufacturers like Samsung Electronics and SK Hynix to prioritize securing inventory at current market prices, with procurement teams actively checking supply and price fluctuations daily [5]. - The rebuilding of the Ras Laffan Industrial City may take years, leading to long-term risks of supply shortages and price volatility, especially since helium is crucial in semiconductor manufacturing and lacks viable substitutes [6]. Group 2: Price Increases in Key Materials - The rise in oil prices has indirectly increased production costs for semiconductor materials, with suppliers notifying price hikes for key components like propylene oxide (PO), which is used to produce diluents [7]. - The price of PGMEA, a diluent, is expected to rise by 40% to 50% due to these cost pressures, affecting suppliers such as DuPont and LG Chem [7]. - Other materials like ethanol and IPA are also seeing price increases, with Korean suppliers announcing double-digit percentage hikes this week [8]. Group 3: Investment Implications - The increasing geopolitical risks are prompting a reevaluation of the semiconductor materials investment logic, which is now driven by a "dual engine" approach [9]. - Short-term supply chain security concerns are accelerating the willingness and urgency of downstream manufacturers to adopt domestic solutions, particularly for critical supply chain segments [9]. - Long-term capital investments are expected to accelerate, with a high certainty of expansion in domestic advanced processes and storage, creating growth opportunities for upstream suppliers [9].
