先进封装的新竞争

Core Viewpoint - The semiconductor industry is experiencing a shift in competitive dynamics, driven by the demands of the AI era, where performance bottlenecks are increasingly occurring outside the chip itself [1] Group 1: Industry Trends - The rise of heterogeneous integration structures, such as chipsets and 2.5D/3D stacking, is crucial for extending Moore's Law in semiconductor packaging [2] - The focus on "power density" is growing due to higher integration levels in semiconductor packaging, leading to increased thermal flux in smaller areas [2] - Advanced packaging is now more about "material design" than "assembly technology," with critical questions surrounding heat dissipation, stress absorption, signal integrity, and maintaining performance during mass production [3] Group 2: Material Requirements - Key materials for semiconductor packaging include high thermal conductivity and insulation materials for bottom filling, which must balance flowability, curing performance, and thermal properties [4] - Multifunctional EMC materials are evolving from simple protective materials to functional materials that control heat, electromagnetic waves, and environmental stress [5] - Fine-pitch metal wiring materials compatible with TGV technology are essential for ensuring electrical reliability and interface adhesion [5] - High-reliability, low-temperature bonding materials are necessary to reduce thermal stress on chips and substrates while maintaining long-term reliability [5] Group 3: Strategic Recommendations - A clear national solution is essential, with public sectors leading in establishing verification and reliability assessment infrastructures [6] - AI should be central to the material development process, leveraging AI to develop materials for AI chips through predictive modeling and simulation [6] - Strategic technology recognition from a supply chain perspective is critical, as advanced packaging materials are core assets linked to strategic industries [7] - The development of specialized talent is vital, requiring a workforce skilled in materials, chemistry, mechanics, electronics, and computer science [7]
