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].

Group 1 - The article highlights the potential supply disruptions of critical semiconductor materials such as helium, diluents, ethanol, and isopropanol (IPA) due to the ongoing conflict involving Iran, raising alarms in the industry [1][2] - Helium is identified as the most concerning material, essential for plasma etching and deposition processes in semiconductor manufacturing, with current spot prices having surged over 50% [1][3] - Qatar, which supplies about one-third of the world's helium, has faced attacks on its LNG production facilities, leading to a reported 17% reduction in LNG export capacity, with recovery expected to take 3 to 5 years [1][2] Group 2 - The reliance on Qatar for helium has pushed large companies to their limits, with potential supply interruptions if the conflict persists [2] - Other materials like diluents, ethanol, and IPA are also experiencing price increases due to the surge in oil prices linked to the conflict, with propylene oxide (PO) prices rising over 43% since the beginning of the month [2][3] - Major suppliers of PO, such as DuPont and Dow, have issued price increase notifications, with PGME and PGMEA prices rising by 40% to 50% [3] Group 3 - Ethanol and IPA are also entering a price increase phase, with domestic suppliers in South Korea notifying customers of price hikes exceeding 10% due to rising costs from oil price surges [3][4] - Despite the rising costs of these materials, they constitute a small portion of the overall semiconductor production costs, thus not expected to directly impact chip prices [4] - Companies like Samsung Electronics and SK Hynix are actively managing their inventory in response to market price fluctuations [4]
