What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Choose a foundry by matching its exact process, design tools, qualified manufacturing site, delivery commitments, and total cost to your chip and product schedule—not by node name alone. Build a shortlist against defined requirements, then ask each supplier for evidence that applies to the specific process revision and site you would use.
Start with the chip and the manufacturing program
Write down what the product must do and what the manufacturing program must support before comparing suppliers. At a minimum, capture:
- End use, performance, power, die-area and unit-cost targets.
- Expected production volume, ramp timing, design schedule, and intended product lifetime.
- Reliability requirements, including any end-market or customer-specific qualification needs.
- Required process characteristics: logic or specialty technology, memory, analog, RF, voltage, image sensing, power management, and packaging or integration.
Use these requirements to identify viable process options. A smaller node is not automatically a better fit: its cost, design complexity, or supporting ecosystem may not benefit a product that depends more heavily on analog, high-voltage, embedded nonvolatile memory, RF, or another specialty capability. Samsung Foundry’s published portfolio, for example, spans logic and specialty options including eNVM, RF, CIS, high-voltage, and BCD; that illustrates why process fit is broader than node naming, not how Samsung compares with another supplier.
Check that the process is design-ready
A process is only a practical option if your team can design, verify, and tape out against its supported collateral on the schedule you need. The OECD explains that electronic design automation (EDA) tools use a process design kit (PDK) containing process design rules to check whether a design can be manufactured. TSMC describes EDA certification and ecosystem components as part of its Open Innovation Platform. These sources establish why enablement matters; they do not independently rank foundry ecosystems.

- Check availability and support status for the required EDA flows, libraries, qualified IP, verification collateral, and engineering assistance.
- Separate components available now from those in development, and confirm which release the supplier will support.
- If the design depends on advanced packaging, chiplets, or heterogeneous integration, verify that the required packaging and integration path is supported for your product.
Do not treat a roadmap item or general ecosystem description as proof that a specific flow, IP block, or packaging option is ready for your design.
Verify qualification, quality, and reliability
Request qualification and reliability evidence for the precise process revision and manufacturing site under consideration. For a recently introduced or ramping process, establish its qualification stage and what the available evidence covers; do not assume that maturity on another process or at another site transfers automatically.
Review the supplier’s quality system and ask how it handles process control, nonconforming product, failure analysis, corrective actions, and engineering changes. Samsung Foundry’s published description refers to an IATF 16949-based quality system, statistical process control, controls for nonconforming products, and supplier assessments that consider technology, quality, delivery, cost, and improvement. These are statements about Samsung’s systems, not a sector-wide guarantee. TSMC also describes qualification and quality controls across technology development and production.

For automotive and other reliability-sensitive products, check requirements at the process and application level. TSMC reported that its N3A automotive process completed automotive-grade qualification and offered an automotive design-enablement platform in 2025. This is an example of process-specific qualification; it does not establish the status of other TSMC processes or suppliers’ offerings.
Ask for product-relevant yield, capacity, and schedule evidence
Yield depends on the design, process maturity, and manufacturing context, so request evidence relevant to comparable designs and the production stage you expect to enter. Clarify the supplier’s ramp assumptions and how it will report progress. Also distinguish announced capacity plans from capacity committed to your program.
For the intended process and site, establish what wafer capacity is available to your program, how allocation works, what cycle time is expected, and how delivery risks are escalated. TSMC lists capacity response, cycle time, yield ramp, delivery, and supply assurance among its manufacturing strengths. That is a vendor description, not an independent performance comparison or a commitment to an individual customer.
Rank #3
- EVALUATION BOARD: NRF9151-DK development board from Nordic Semiconductor designed for cellular IoT and GNSS applications

TSMC reported annual manufacturing capacity above 17 million 12-inch-equivalent wafers in 2025. This is a company-wide figure, not evidence that a particular process, fab, or customer has that capacity available.
Compare the full cost and operating model
Compare quotes on a like-for-like basis: the same expected volume, die size, process option, packaging route, and schedule. A wafer price alone does not describe the cost of manufacturing a working, delivered chip. Include:
Recommended Free Tools
- Mask and non-recurring engineering (NRE) costs.
- Engineering support, qualification effort, and the likely effect of yield on usable units.
- Packaging, assembly, test, logistics, and inventory costs.
- The cost and risk of a redesign or later transfer to another process or site.
Ask each supplier to state what its quote includes, what is separate, and which assumptions could change the price or schedule. TSMC’s description of online engineering and logistics collaboration gives examples of operational information a buyer may seek, such as pilot-lot, yield, wafer-acceptance-test, quality and reliability, and lot-status information.

Public sources do not establish comparable customer-specific pricing or yield across foundries. Request those details directly under appropriate confidentiality terms rather than substituting industry-wide assumptions.
Evaluate the actual site and continuity plan
Map the process you are considering to the site where it will be manufactured. Ask whether the same process is qualified at another site, what would be required to move production, and what continuity plan applies if a fab or region is disrupted. Location can also affect logistics, engineering access, customer requirements, and contractual or regulatory restrictions.
TSMC lists operations in Taiwan, Nanjing, Arizona, and Japan, and says a specialty-technology fab was under construction in Dresden. Its public location information does not mean every process is offered at every site. Confirm availability and qualification for the exact process and location in your supplier discussions.

Use a consistent shortlist scorecard
Score each candidate against requirements your team has set, and record the evidence behind each assessment. A qualitative rating such as “meets,” “open,” or “does not meet” is more useful than an unsupported numerical score. Keep supplier claims separate from verified evidence and contractual commitments.
| Comparison area | What to assess | Evidence to record |
|---|---|---|
| Process fit | Performance, power, area, analog/RF/memory options, voltage, and lifecycle fit | Exact process and options; supplier confirmation against product requirements |
| Design readiness | PDK, EDA, IP, libraries, verification, engineering support, and packaging | Available versions and release status for the planned tape-out |
| Manufacturing evidence | Qualification, reliability, process control, yield learning, and failure analysis | Process- and site-specific records, with stage and scope identified |
| Execution | Capacity, allocation, ramp schedule, cycle time, delivery, and escalation | Program-specific availability, assumptions, and commitments |
| Economics | Wafer and mask costs, NRE, yield-adjusted cost, packaging/test, logistics, and transfer cost | Comparable quote and stated inclusions, exclusions, and assumptions |
| Resilience | Site location, multi-site qualification, continuity, and supply assurance | Applicable site qualifications and a defined continuity plan |
| Commercial fit | Forecast flexibility, contract terms, support model, and confidentiality/IP arrangements | Written terms that match the program’s requirements |
Public information can explain why these areas matter, but it does not provide an independent cross-foundry comparison. Base any score on supplier-specific evidence and your own product requirements.
