Foundry product count measures the number of different customer products a foundry manufactured during a disclosed period.

TSMC said it manufactured 12,682 different products in 2025.

Product breadth was much larger than customer breadth

TSMC served 534 customers in the same year. A simple division gives roughly 24 products per customer, but that average is only a breadth indicator because TSMC does not disclose an even product distribution across customers.

The useful signal is that one customer relationship can encompass many product programs.

Products sit on top of a broad technology stack

TSMC also deployed 305 distinct process technologies. Foundry Process Technology Count describes the manufacturing toolkit, while product count describes how many customer designs used that toolkit.

Do not turn product count into a revenue proxy

A product can be high-volume or low-volume, mature-node or leading-edge, and new or established. Two years with the same product count can therefore have very different revenue and margin outcomes.

Pair the count with Foundry Customer Count and process-node revenue mix.

Where this concept fits

Customer concentration and manufacturing breadthCurrent relationship
Largest, second-largest, and top-ten customer concentration show dependence on major customers, while customer count, product count, and process-technology count show the breadth of the manufacturing ecosystem. Breadth does not negate concentration because a small number of customers can still drive most revenue.

Platform and process-node mix
HPC, smartphone, IoT, automotive, and digital-consumer-electronics revenue mix show where foundry demand originates. Advanced-technology wafer revenue mix and process-node revenue mix show which manufacturing generations monetize that demand without treating end-market categories as process nodes.

Capacity, utilization, output, pricing, and yield
Annual 12-inch-equivalent capacity and wafer manufacturing capacity describe production scale, capacity utilization shows how much of that scale is being used, wafer shipments measure output, wafer average selling price measures realized pricing, and manufacturing yield indicates how effectively processed wafers become usable product.
