1 Under-the-Radar AI Semiconductor Stock to Buy Hand Over Fist, According to Wall Street - The Motley Fool

The semiconductor industry lies at the heart of the artificial intelligence (AI) revolution, with advanced chips and data center components being essential for developing and deploying AI models. Whil... Read original →

Cohu’s surge stems from the unavoidable complexity of sub-3nm AI chip manufacturing. Its Neon platform—merging infrared vision with AI-driven defect detection—directly addresses yield bottlenecks in HBM4/5 stacked memory, filling a critical gap left by EUV lithography. Geopolitical export controls from the U.S., Japan, and the Netherlands are inflating localization costs for fabs, yet Cohu benefits as a U.S.-based test equipment vendor deemed supply-chain secure. While Advantest and Tokyo Seimitsu sharpen their knives, Cohu’s Eclipse platform targets data-center-specific testing, turning heterogeneous integration (GPU+CPU+HBM) into a defensible moat. Over the next 12–24 months, as AI chips grow increasingly customized, testing will shift from a cost center to a performance gatekeeper. If Cohu locks in partnerships with TSMC (Taiwan, China) and SK Hynix on advanced packaging lines, its $750M HPC pipeline could materialize ahead of schedule—though earnings remain hostage to semiconductor capex cyclicality.
