Applied Materials (AMAT.US) saw its stock surge nearly 9% on Wednesday following the semiconductor equipment maker's introduction of two new manufacturing tools. These tools are designed for atomic-level precision and are tailored for the next generation of artificial intelligence (AI) chips. Year-to-date, the stock has climbed 50%.
The new systems aim to fabricate the smallest structural features for the most advanced logic chips. Surging demand for AI computing power has driven the industry to adopt gate-all-around (GAA) transistor architecture at the 2-nanometer node. Applied Materials noted that upcoming AI GPUs are expected to integrate over 300 billion transistors in an area the size of a postage stamp. Without proper isolation, electrons can spread to adjacent transistors, causing parasitic capacitance—an unintended resistive effect between transistors that slows signal transmission, increases power consumption, and reduces chip efficiency.
Currently, silicon oxide is used to isolate atomic-scale trenches among billions of transistors. However, these trenches can degrade over time, leading to diminished chip performance. Applied Materials' new Applied Producer Precision Selective Nitride PECVD system deposits a dense nitride layer on top of the silicon oxide, enhancing the isolation layer's resistance to subsequent process steps and preventing material erosion. Leading logic chipmakers have already begun adopting this system for 2-nanometer and smaller GAA process nodes.
The company also unveiled its second new tool, the Trillium ALD system. Highly customized for GAA applications, it offers capabilities for thinner work function metals and zero-volume dipole layer materials, addressing space constraints in GAA structures. Applied Materials indicated that this system is also being used by top logic chip manufacturers for 2-nanometer and beyond GAA nodes.
Prabu Raja, President of Applied Materials’ Semiconductor Products Group, stated, "At the most advanced angstrom-scale logic nodes, chip performance and power efficiency are increasingly determined by materials engineering. Leveraging our foundational leadership in this field, these deposition systems will enable our customers to achieve critical transistor enhancements essential to the AI computing roadmap."
Despite the sharp rise in Applied Materials’ share price, several analysts remain optimistic. Bank of America analyst Vivek Arya believes chip equipment spending will continue to grow, naming Applied Materials as the firm’s top pick in the semiconductor equipment sector. Deutsche Bank recently added Applied Materials to its list of preferred tech stocks for the next 12 months. Analyst Melissa Weathers highlighted that the company stands to benefit from recent strength in the chip industry, a recovery in DRAM demand, and increased capital expenditure from TSMC.
