China’s semiconductor landscape is undergoing a decisive structural shift as the leading manufacturers and packaging firms on the Shanghai STAR Market report a return to full capacity. Following a period of sluggish demand and inventory corrections, the industry is riding a new wave of growth anchored by the global artificial intelligence (AI) boom. During a recent collective earnings briefing, industry titans including CR Micro and SJ Semi revealed that their production lines are humming at maximum utilization, signaling a robust recovery for the domestic supply chain.
This resurgence is not a simple return to the status quo but a calculated pivot toward high-value sectors. While traditional consumer electronics show only signs of a 'weak recovery,' the demand for AI servers, high-performance computing (HPC), and new energy vehicle components is explosive. CR Micro, a major integrated device manufacturer, reported that its power management chips are now being integrated into top-tier AI server ecosystems, with the value per unit potentially representing up to 60% of power solution costs. This transition from low-margin consumer chips to sophisticated industrial and server components marks a maturing of China’s domestic capability.
In the realm of Outsource Semiconductor Assembly and Test (OSAT), SJ Semi is leading the charge into advanced packaging technologies like 2.5D and 3D integration. These technologies are critical for the performance of modern AI accelerators, acting as the bridge between logic and memory. As major Taiwanese packaging firms shift their focus toward high-end international AI orders, Chinese firms are capturing the overflow, successfully validating new production lines for domestic clients. This 'overflow effect' combined with aggressive R&D is allowing Chinese firms to rapidly climb the technology ladder.
Looking ahead, the strategic focus for these firms has moved beyond mere survival to scaling for the next technological cycle. Companies like Jinghe Integration and Yanmai Technology are doubling down on 'intelligent manufacturing' and specialty processes for automotive microcontrollers and silicon photonics. By aligning their capital expenditure with the '15th Five-Year Plan' objectives, these STAR Market entities are positioning themselves as the indispensable backbone of China’s self-reliance strategy in an increasingly bifurcated global tech market.
