The semiconductor industry's innovation focus is shifting from transistor scaling toward system-level integration. A recent report aggregating research from institutions including Unimicron, Applied Materials, AMD, UCLA, A*STAR IME, Hprobe, Wooptix, and Nexperia outlines eight key technology trends shaping advanced packaging over the next decade.
Co-packaged optics (CPO), hybrid bonding, and wafer-scale integration are emerging as the foundational pillars of this transition. The supply chain is converging on a shared objective: enhancing system performance, reducing power consumption, and achieving higher integration density in the post-Moore era.
Unimicron examines CPO architectures for optoelectronic convergence. Applied Materials reviews recent progress in hybrid bonding. AMD focuses on failure analysis of thermal interface materials in high-performance processors. UCLA presents a roadmap for heterogeneous wafer-scale integration. A*STAR, Hprobe, Wooptix, and Nexperia contribute insights across packaging simulation, sensor testing, advanced metrology, and thermal reliability, respectively.
Key technical figures illustrate cross-sections of fluxless Cu-Cu thermocompression bonding, shear strength variations after 110 thermal cycles, and void formation in thermal interface materials captured via scanning electron microscopy and acoustic micro-imaging. Collectively, these advancements define the trajectory of AI-era advanced packaging, optical interconnects, and thermal management technologies.
