What is Semiconductor Fabrication?
Semiconductor Fabrication manufactures chips through photolithography and chemical processes at nanometer precision, determining chip performance and power efficiency. Fab capacity constrains AI hardware supply.
This AI hardware and semiconductor term is currently being developed. Detailed content covering technical specifications, performance characteristics, use cases, and purchasing considerations will be added soon. For immediate guidance on AI infrastructure strategy, contact Pertama Partners for advisory services.
Semiconductor fabrication constraints directly determine AI hardware availability, pricing, and delivery timelines that affect every company deploying compute-intensive AI workloads. Understanding fabrication supply chains enables mid-market companies to make strategic procurement decisions, securing hardware 3-6 months ahead of anticipated shortage periods that inflate GPU prices by 50-200%. The knowledge also informs build-versus-buy decisions for AI infrastructure, since fabrication-driven hardware cost trajectories determine when cloud API pricing becomes more economical than owned infrastructure.
- Determines chip performance and power.
- Process nodes: 5nm, 3nm, 2nm (smaller = better).
- Massive capital investment (tens of billions).
- TSMC dominates leading-edge fabs.
- Geopolitical considerations (Taiwan concentration).
- Capacity constraints impact AI hardware availability.
- Monitor TSMC and Samsung capacity allocation announcements quarterly, since AI chip production timelines of 6-18 months affect hardware availability and pricing for downstream AI deployments.
- Understand that leading-edge fabrication (3nm and below) is concentrated among 2-3 manufacturers, creating supply chain risks that affect GPU availability and pricing unpredictably.
- Track geopolitical developments around Taiwan semiconductor manufacturing since 90% of advanced AI chip fabrication depends on facilities vulnerable to regional supply disruptions.
- Evaluate mature node alternatives (14nm-28nm) for inference-specific AI accelerators that deliver adequate performance at 60-80% lower cost than leading-edge alternatives.

Common Questions
Which GPU should we choose for AI workloads?
NVIDIA dominates AI with H100/A100 for training and A10G/L4 for inference. AMD MI300 and Google TPU offer alternatives. Choose based on workload (training vs inference), budget, and ecosystem compatibility.
What's the difference between training and inference hardware?
Training needs high compute density and memory bandwidth (H100, A100), while inference prioritizes latency and cost-efficiency (L4, A10G, TPU). Many organizations use different hardware for each workload.
More Questions
H100 GPUs cost $25K-40K each, typically deployed in 8-GPU nodes ($200K-320K). Cloud rental is $2-4/hour per GPU. Inference hardware is cheaper ($5K-15K) but you need more units for serving.
