4 Semiconductor Stocks to Buy Right Now to Ride on the AI Capex Boom - Yahoo Finance

As artificial intelligence (AI) becomes one of the most prominent investment themes in the technology sector, the rapid surge in AI infrastructure spending is creating significant opportunities for se... Read original →

The AI capex surge is triggering a deep restructuring across the semiconductor stack: exploding HBM demand is accelerating DRAM scaling to 1β/1γ nodes and boosting utilization of EUV and advanced packaging. TSMC in Taiwan, China dominates 3nm and CoWoS capacity, making it the sole viable foundry for NVIDIA and hyperscalers—but geopolitical friction is spurring the U.S. and Japan to fast-track domestic alternatives. Micron’s early HBM wins face counterpressure from Samsung’s GAA transistors and silicon photonics integration. Meanwhile, Texas Instruments benefits structurally as AI server power complexity drives analog chip demand. Within 18 months, HBM4 standardization will widen the technology gap, sidelining players lacking TSV or hybrid bonding capabilities. Tightening U.S. CHIPS Act compliance scrutiny may also raise operational costs for non-U.S. firms, forcing equipment vendors like FormFactor to reconfigure global support networks.
