SEMI Raises 2027 300mm Fab Spending Forecast to $151B as AI Demand Accelerates

SEMI has sharply upgraded its outlook for the equipment needed to build 300mm semiconductor wafers. Its latest forecast calls for global spending of $151 billion in 2027, up 14% from the projected $133 billion in 2026 and roughly 26% above the $120 billion forecast published in October 2025.

The change reflects more than a cyclical recovery. SEMI links the stronger outlook to accelerating demand for AI chips in data centers and edge devices, along with efforts by major regions to build more localized semiconductor ecosystems and resilient supply chains.

Why AI is lifting semiconductor capital spending

AI workloads are increasing demand for both advanced processors and the memory needed to feed them. That is pushing manufacturers to expand capacity across leading-edge logic and high-performance memory rather than concentrating investment in a single part of the supply chain.

Memory is a major part of the increase. SEMI expects 300mm memory-fab equipment investment to reach $52 billion in 2026, the first time the sector is projected to pass $50 billion, before rising another 11% to $57 billion in 2027. DRAM equipment spending is forecast to grow 29% to $37 billion in 2026, while 3D NAND spending is expected to increase 28% to $14 billion.

The practical implication is that AI infrastructure is driving investment throughout the manufacturing stack: advanced process equipment, memory capacity, packaging, interconnects and power-management technologies. The available forecasts support a strong investment thesis, but they remain projections rather than confirmed spending totals.

SEMICON Taiwan 2026 turns that investment story into an industry agenda

The same shift will shape SEMICON Taiwan 2026, which is scheduled for September 2–4 at Taipei Nangang Exhibition Center, or TaiNEX Halls 1 and 2. Related forums begin August 31 during International Semiconductor Week.

The event’s theme, “Transform Tomorrow,” reflects a move from focusing only on smaller process nodes toward broader system-level innovation. The published agenda covers advanced manufacturing, advanced packaging, AI semiconductors, smart manufacturing, quantum technology and collaboration across the semiconductor supply chain.

Organizers expect more than 1,300 exhibitors, approximately 4,300 booths and over 100,000 industry professionals from 65 countries. The scale is significant because the event brings together wafer manufacturers, equipment and materials suppliers, IC designers, system companies and startups in one setting.

The first full-day executive summit focuses on AI deployment

SEMI is expanding the CEO Summit and Ecosystem Executive Summit into a full-day program for the first time on September 2. Its agenda is built around the technologies required to move AI from demonstrations to deployment at scale, including cloud and accelerated computing, memory, interconnects, power management and system co-design.

The focus is notable because AI performance increasingly depends on coordination between multiple parts of the hardware platform. Process technology remains important, but so do memory bandwidth, package architecture, networking, power delivery and the equipment and materials that connect those pieces.

Advanced packaging and chiplets move to the center

Advanced packaging is one of the clearest themes linking SEMI’s spending forecast with the Taiwan event. SEMICON Taiwan 2026 will highlight 3D ICs, chiplets and heterogeneous integration, with a new Chiplet Pavilion and dedicated Smart Fab and Quantum Technology zones.

SEMI has also worked with TSMC and ASE to launch the SEMI 3DIC Advanced Manufacturing Alliance, a partnership intended to strengthen collaboration around advanced packaging manufacturing.

These developments point to a broader change in how the industry is approaching AI hardware: performance gains are increasingly pursued through coordinated improvements in chips, memory, packaging and manufacturing systems—not through process scaling alone.

What to watch at SEMICON Taiwan 2026

For visitors and technology companies, the event’s most relevant themes are:

• AI chips and accelerated computing, including the infrastructure required for data centers and edge systems.
• High-bandwidth memory and memory manufacturing, supported by the sharp rise in projected memory equipment spending.
• Advanced packaging, including 3D ICs, chiplets and heterogeneous integration.
• Smart manufacturing, where AI is applied to factory operations and production systems.
• Quantum technology and emerging architectures, represented by a new dedicated zone.
• Ecosystem partnerships, spanning design, manufacturing, equipment, materials, packaging and system applications.

Taken together, SEMI’s revised forecast and SEMICON Taiwan’s program describe the same market transition: AI is expanding semiconductor investment not only by increasing demand for compute, but also by raising the importance of memory, packaging, power, interconnects and coordinated supply-chain capacity.
