Core Viewpoint - The article discusses the ongoing global AI wave and the resulting shortage of storage chips, which is driving an expansion in production capacity, particularly in high-end storage products like HBM (High Bandwidth Memory) [3][4]. Group 1: Storage Shortage and Expansion Expectations - The current upcycle in storage chips is primarily driven by the explosive demand from AI servers and multimodal applications, leading to shortages and price increases [5]. - In October, prices for various storage models surged, with increases ranging from 40% to 100%. Major manufacturers like SanDisk announced a 50% price hike for NAND flash memory due to heightened demand and tight wafer supply [6]. - The shift of international manufacturers away from low-end markets to focus on high-end products has exacerbated supply shortages, particularly affecting consumer electronics like smartphones and PCs [6][7]. Group 2: Performance of Domestic Semiconductor Equipment - The semiconductor equipment sector has shown strong performance, with the total revenue for the sector reaching 85.21 billion yuan in the first three quarters of 2025, a year-on-year increase of 31.54% [8]. - Companies like拓荆科技 reported a revenue of 4.22 billion yuan, up 85.27%, and a net profit increase of 105.14% [8][9]. - Inventory and contract liabilities are at historical highs, indicating strong order visibility and future revenue potential for equipment manufacturers [9]. Group 3: Domestic Equipment Manufacturers' Growth - Domestic storage leaders like Yangtze Memory Technologies and Changxin Memory are expected to enhance their production capacity post-IPO, further boosting the demand for domestic equipment [7]. - The semiconductor equipment market is benefiting from the expansion of storage production, with key equipment types like etching and deposition devices seeing increased demand [9][10]. - Companies such as北方华创 and中微公司 are achieving significant milestones in equipment delivery and product development, positioning themselves well in the high-end semiconductor equipment market [10].
