How TSMC Makes Money

Revenue from manufacturing chips at 7nm, 5nm/4nm, 3nm and now 2nm process nodes for customers such as Apple, Nvidia, AMD, Qualcomm and MediaTek. These wafers carry the highest prices and margins in TSMC's portfolio, and AI accelerators plus flagship smartphone processors drive most of the demand. TSMC reports node mix quarterly in its management report.

Revenue from manufacturing at 16nm through 180nm process nodes, serving automotive, industrial, analog, power management, RF, and embedded memory markets. These processes are characterized by long lifecycles, stable demand, and lower per-wafer prices than advanced nodes, but also lower capital intensity due to depreciated equipment. Specialty processes include TSMC's high-voltage, embedded flash, BCD (Bipolar-CMOS-DMOS), and silicon photonics platforms. The automotive segment within specialty processes is growing as electric vehicles require substantially more semiconductor content per vehicle than conventional automobiles. TSMC's 28nm node remains the world's most widely deployed logic process.

Revenue from TSMC's advanced packaging technologies, which physically integrate multiple chips into a single package with high-density interconnects. CoWoS (Chip on Wafer on Substrate) uses a silicon interposer to connect AI compute dies with HBM memory stacks. SoIC (System on Integrated Chips) enables face-to-face chip bonding for extreme density. InFO (Integrated Fan-Out) is used in Apple's A-series chips to reduce package thickness. This segment is growing significantly faster than wafer revenue as chiplet architectures become mainstream, and its revenue contribution is expected to increase materially through 2026 and 2027 as TSMC invests in dedicated packaging capacity.

Revenue from photomask manufacturing, which produces the patterned optical templates used in chip lithography. TSMC manufactures its own photomasks internally for quality control and supply chain security reasons, and provides mask services to certain customers as part of prototype and low-volume manufacturing programs. This revenue stream is small in terms but important as a vertical integration element of the company's overall manufacturing capability. Mask technology, particularly for EUV processes, is an area of ongoing R&D investment as the complexity and cost of leading-edge reticles have increased with each process generation.

Revenue from process engineering services, design enablement, and in limited cases, technology licensing. TSMC provides design support services to customers through its Open Innovation Platform ecosystem, which includes process design kits, standard cell libraries, IP blocks, and co-optimization programs. The company also generates a small amount of licensing income from intellectual property related to its process technologies, though TSMC is generally protective of its manufacturing IP and does not engage in broad licensing of its core process knowledge. This revenue stream is primarily strategic in nature, supporting customer design capability rather than generating material standalone income.
