La refonte des dépenses d'investissement mondiales dans les semi-conducteurs : l'impact profond des procédés de pointe pilotés par l'IA, de l'encapsulation avancée et de la géopolitique

Introduction

In recent years, the global semiconductor industry has been undergoing a structural transformation driven by AI. On one hand, the explosion of generative AI has fueled an explosive demand for high-performance GPUs, ASICs, and large-scale data center solutions, directly pushing the R&D and manufacturing needs for the most advanced chips (such as 2nm, 3nm) to historic highs. On the other hand, rising geopolitical risks and protectionism in trade have fundamentally changed the direction of semiconductor capital expenditure—shifting from simple cost optimization to "de-risking" and "localization" strategies. This report will go beyond simple capacity news to deeply analyze the technological drivers, the logic of industry chain reshaping, and the evolution of regional competitive landscapes behind these investments.

We will not only focus on how the AI chip demand from giants (such as NVIDIA, AMD) drives investment in upstream equipment (such as ASML, Applied Materials) and materials (such as photoresists, specialty gases), but also examine how downstream packaging (Advanced Packaging) is evolving from simple contract manufacturing to a key technological barrier determining chip performance. Therefore, this paper will conduct a panoramic analysis from four dimensions: technological roadmaps, industry chain impact, competitive landscape, and regional competition.

Background

Industry Background The global semiconductor market is at a crossroads under the dual pressures of "demand-driven" and "supply reshaping." AI and HPC (High-Performance Computing) are the biggest growth engines currently, and their demands for computational power far exceed those of traditional applications, forcing all participants to accelerate towards more advanced process nodes and more complex system integrations. Simultaneously, governments worldwide, through policies like the CHIPS Act, are intervening in industry layouts with unprecedented vigor, aiming to build a safer and more resilient semiconductor ecosystem, which gives the geographical distribution of capital expenditure a highly politicized character.

Technological Background The core of competition in technological roadmaps has shifted from simple "process node miniaturization" to "system-level integration" and "heterogeneous computing." Breakthroughs in advanced processes like 2nm and 3nm are not just about performance enhancement; they are a prerequisite for efficiently running specific AI algorithms (such as neural networks). At the same time, advanced packaging (Advanced Packaging), such as Chiplet technology and 2.5D/3D integration, has become the key technology for overcoming traditional chip manufacturing bottlenecks and achieving breakthroughs in system-level computing power. This marks a shift in the industry chain's focus from "miniaturization of single transistors" to "intelligent interconnection of multiple chips."
