Major tech companies, including Apple, are competing for limited supplies, with Nvidia's CEO personally visiting suppliers to secure materials [5][12]. Group 1: Supply Shortage - The shortage of high-end glass cloth is primarily due to the dominance of Nittobo, which holds over 90% of the market share for Low CTE glass cloth, essential for AI chips and high-end processors [10][12]. - The production of Low CTE glass cloth requires high temperatures and expensive materials, making it a complex and costly process. The stability of glass cloth directly impacts the quality of substrates used in electronic devices [7][10]. - The demand for Low CTE glass cloth has surged not only from Nvidia but also from other companies like AMD, Google, and Amazon, leading to a situation similar to the DRAM chip shortage experienced last year [12][13]. Group 2: Market Dynamics - Nittobo has been the exclusive supplier for Nvidia's AI chips due to its ability to meet stringent quality requirements. The company has a long history in the glass fiber industry, having been established in 1923 [10][11]. - Other companies, such as Taiwan Glass and Taishan Fiberglass, are attempting to enter the market, but Nvidia has been cautious about including state-owned Taishan Fiberglass in its supply chain due to geopolitical sensitivities [15][17]. - Apple has proactively sought alternative suppliers, including Grace Fabric Technology, to secure its supply of Low CTE glass cloth, reflecting the competitive landscape and urgency in the supply chain [19][20].
