5-1-3 MPI Corporation (6223) and Chunghwa Precision Test Technology (6510)'s Probe Cards —— Safeguarding the Lifeline of KGD Yield
AI's Chiplet drive multiplies multi-chip yield issues, KGD critical. Probe cards, for precise microscopic wafer electrical testing, create a high barrier via precision/materials. Their consumable nature (wear, updates) ensures a stable economic model; MPI & CHPT guard advanced packaging yield.
5-1-2 The Harsh Reality of Testing: This Isn't QA, But a 'Capital Allocation Tool'
Semiconductor testing, in advanced processes, is a 'capital allocation tool'. It prevents sunk costs, intercepting defective bare die pre-costly packaging, saving scarce capacity. Maximizes wafer gross margins via precise chip quality pricing & grading tech. This is a strategic risk control for g...
5-1-1 Overall Perspective: What is Packaging? — The End of the Semiconductor Journey and the "Four Sacred Tasks"
Packaging, the chip's 'physical body,' protects fragile bare die. Evolved into sophisticated 'power armor,' it manages AI chip power for stability, shortens transmission via advanced tech, and breaks the memory wall. Not just a shell, it's a physical battleground critical to AI performance and un...
4-3-8 Commander-in-Chief of the AI Compute Network: Accton Technology (2345)'s System-Level Dominance in 800G/1.6T Switches
Accton, the white-box switch leader, capitalizes on the 800G/1.6T upgrade wave. Its AI accelerator card (AI-NIC) business saw 361% YoY growth, its strongest second pillar. Through L11 rack integration and NPO/CPO pre-research, Accton is the commander-in-chief of the 102.4T compute network.
4-3-7 Igniting the Spark of AI: Epitaxial Leader Arima Lasers (3081) and Packaging Veteran Lingsen Precision (3450)
Arima Lasers (3081), global InP epi-wafer choke point, masters silicon photonics' CW laser 'ignition source'; capacity driven by NVIDIA's 20x expansion. Lingsen Precision (3450) shifts from traditional packaging to high-ASP COS/ELS, achieving 20% operating margin by 2025, a high-end P&T transform...
4-3-6 CPO Packaging Special Forces: The Precision Alignment of InnoLight-KY (6451), Optiworks (3363), and BroadWeb (3163)
Precision is key beyond 1.6T. InnoLight-KY (6451) masters 102.4T SiP P&T. Optiworks (3363) leverages patented ReLFACon™ FAU for TSMC COUPE 1.6T CPO link. BroadWeb (3163) dominates high-density Fiber Harness external optical management, targeting high margins.
4-3-5 Ultimate Combination —— CPO (Co-Packaged Optics) and TSMC COUPE
TSMC's COUPE via SoIC-X enables 3D PIC/EIC vertical stacking, cutting transmission distance. Against laser heat sensitivity, ELS/RLS (External Laser Source) architecture emerged, relocating heat from chassis. This "full-stack" strategy creates a "de-packaging" survival crisis for traditional modu...
The Leading Player in 4-3-4 CPO: Google's Co-Packaged Optics Ambitions and Broadcom's Bailly Platform
Google pushes OCS & CPO tech for power saving in millions of TPU clusters. Broadcom's Bailly platform, the first commercial 51.2T/102.4T CPO system, cuts 70% power. This revolution vertically compresses supply chain, making silicon photonics dominant solution post-2028.
4-3-3: Leading Module Players in Taiwan: E-Da Technology (4977), LuxNet Corp. (4979), and OptiWorks Inc. (6442)'s 1.6T Dividend
Taiwanese firms shifted value in 1.6T era. E-Da Technology deeply partnered with Marvell for co-dev; LuxNet Corp. monopolized US CSP access via 6,912+ core panels; OptiWorks Inc. leveraged global OEM resilience/yield to become Broadcom's key production hub.
