Choose a foundry by matching a specific process, design ecosystem, qualified manufacturing site, schedule, cost and supply plan to your chip—not by picking the smallest advertised node or the best-known supplier. Shortlist candidates against the same requirements, then ask each for evidence tied to the exact process revision, site and production stage you would use.
What should you compare when choosing a foundry?
Start with a consistent scorecard. For each candidate, record the evidence you have, what is still unconfirmed, and how important that factor is to your product. Weight the factors according to the chip’s needs; a design that depends on high-voltage analog, for example, should not treat that capability as interchangeable with an advanced logic node.
| Dimension | Evidence to compare |
|---|---|
| Process fit | Performance, power, area, analog/RF/memory and voltage options, plus expected product lifetime |
| Design readiness | PDK release, supported EDA flows, libraries, IP, verification collateral, engineering help and packaging options |
| Manufacturing maturity | Qualification stage, reliability evidence, process controls, yield learning and failure-analysis support |
| Execution | Customer-available capacity, allocation, ramp schedule, cycle time, delivery and escalation process |
| Economics | Wafer, mask and NRE charges, yield-adjusted cost, packaging, test, logistics and future transfer or redesign costs |
| Resilience and commercial fit | Qualified sites, continuity plans, forecast flexibility, contract terms, support model and IP/confidentiality arrangements |
Use a consistent evidence standard for every candidate. Public capability descriptions are useful for identifying questions, but they are not independent benchmarks or substitutes for customer-specific commitments. Public information does not establish comparable foundry pricing, process-specific yield or contract allocation; request those details directly under appropriate confidentiality terms.
Which process is right for your chip?
Translate the product into manufacturing requirements
Before asking for proposals, document the chip’s end use, performance and power targets, die-area and cost constraints, forecast volume, reliability needs, design schedule and expected product lifetime. Convert those into process requirements: logic node or specialty technology; memory and analog needs; operating voltage; RF, image-sensor or power-management features; and packaging or integration requirements.

A smaller node is not automatically the better choice. It may add cost and design complexity without improving the product enough to justify them. Samsung Foundry’s public portfolio, which includes logic processes and specialty options such as embedded non-volatile memory, RF, CMOS image sensors, high-voltage and BCD technologies, illustrates why process fit is broader than node naming. Those are Samsung’s capability descriptions, not a comparative ranking.
Confirm the exact process and revision
Ask each candidate: “Which exact process and revision meet our requirements, and what is their qualification and production status at the intended site?” A process family name alone does not establish that the needed options are available, qualified or in production where your wafers would be made.
Can your design team tape out on the process in time?
Design enablement can determine whether a nominally suitable process is practical for your schedule. The process design kit (PDK) supplies process-specific design rules and other information used in the design and verification flow. The OECD describes EDA tools as using PDK design rules to check whether a design can be manufactured on a process; TSMC describes EDA certification and ecosystem components through its Open Innovation Platform.

Check that the materials and support you need exist for the actual tape-out date—not only on a roadmap. Ask: “Which PDK version, EDA flows, libraries, IP blocks and verification collateral will be available and supported by our tape-out date?” Confirm the status of each item, who supports it, and whether any critical components remain in development.

If your chip relies on advanced packaging, chiplets or other heterogeneous integration, confirm those services and design interfaces as part of the same feasibility check. TSMC describes advanced packaging within its service ecosystem; that does not independently establish how its offering compares with another supplier’s.
How do you judge process quality and maturity?
Request qualification evidence and reliability data relevant to your product and application. For a new or recently ramped process, identify the qualification stage and establish whether the evidence applies to the precise process revision and manufacturing site in your proposal. A supplier’s general quality credentials do not by themselves answer those product-specific questions.

Ask what controls are used in production and how the supplier handles defects, nonconforming material, failure analysis and corrective actions. Samsung’s published quality policy describes an IATF 16949-based quality system, statistical process control, nonconforming-product controls and supplier assessments that consider technology, quality, delivery, cost and improvement. These are Samsung’s statements about its own systems, not a guarantee across the industry. TSMC also describes qualification and quality controls across technology development and production.
Ask the supplier: “What yield, reliability and process-control evidence can you provide for designs and production stages comparable to ours?” Establish what “comparable” means for your design class and process maturity rather than treating an unattributed or broad yield figure as a forecast for your chip.

Can the foundry meet your volume and schedule?
Request evidence for the specific process and site: expected wafer starts available to your program, allocation policy, ramp assumptions, cycle time, delivery performance and escalation path. Distinguish capacity announced for a facility or process from capacity committed to your customer program. Ask: “What capacity and schedule can you commit to, and how will allocation, cycle-time changes and ramp risks be handled?”

Scale figures need careful interpretation. Taiwan Semiconductor Manufacturing Company reported annual manufacturing capacity above 17 million 12-inch-equivalent wafers in 2025. That is a company-wide figure, not a commitment or availability estimate for a particular process, fab or customer. TSMC also lists capacity response, cycle time, yield ramp, delivery and supply assurance as manufacturing strengths; these are vendor descriptions, not independent performance comparisons or guarantees for a buyer.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What is the full cost of manufacturing?
Compare proposals on the same assumptions: forecast volume, die size, process option, packaging route and schedule. Look beyond wafer price to masks and non-recurring engineering (NRE), engineering support, expected yield, assembly and test, logistics, inventory, qualification effort, and the cost of a redesign or later transfer. Ask which items are included in the quote, which are separate, and what assumptions could change the total.
Operational visibility can affect execution as well as administration. TSMC describes online engineering and logistics collaboration that can include pilot-lot, yield, wafer-acceptance-test, quality/reliability and lot-status information. Ask what comparable information your team would actually receive, when it would be available, and who can act on it; the public description is not evidence that another supplier offers the same service.

How should location and supply continuity affect the decision?
Map the proposed process to the actual manufacturing site. Ask whether that same process is qualified at another site and what continuity plan applies if a facility or region is disrupted. Consider how location affects shipping, customer requirements, access to engineering support and applicable regulatory or contractual restrictions.
TSMC lists operations in Taiwan, Nanjing, Arizona and Japan, and says a specialty-technology fab was under construction in Dresden. A list of locations does not mean every process is available or qualified at every one. Ask: “Is this process qualified at another site, and what continuity plan applies to a site or regional interruption?”
What extra checks apply to automotive and other reliability-sensitive chips?
Verify qualification and reliability evidence for the particular process, application and design collateral your product requires. Do not infer that one process’s qualification applies to another process or supplier. As a specific example, TSMC reported that its N3A automotive process completed automotive-grade qualification and offered an automotive design-enablement platform in 2025. That example does not establish the qualification status of other processes.
What should you get in writing before choosing?
Make the decision on supplier-specific evidence and commitments, not a score based on public claims alone. For each finalist, resolve the open items below with the people responsible for process, design enablement, manufacturing, quality and commercial terms.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors- Which process revision and manufacturing site are covered, and what is their qualification and production status?
- Which design files, flows and support resources will be available for the planned tape-out?
- What product-relevant manufacturing and reliability evidence can the supplier provide?
- What capacity and delivery schedule are committed, and how are allocation changes and escalation handled?
- What costs are included or excluded, and what assumptions underlie the quote?
- What failure-analysis, engineering-change, quality-incident and production-ramp support is available?
Keep the comparison tied to your requirements: record each supplier’s evidence, unresolved assumptions and contractual commitments separately. That makes it easier to distinguish a genuine fit from an attractive but unverified capability description.
