Supply chain decisions rarely get more consequential than the choice of who makes your chips. Semiconductors sit at the foundation of nearly every modern product category – consumer electronics, automotive systems, industrial equipment, medical devices – and when the supply goes wrong, everything downstream goes wrong with it.
The shortages of 2020 to 2022 made that point at scale. Companies that had treated semiconductor supplier procurement as a commodity purchase found themselves unable to build products, while those with deeper supplier relationships and diversified sourcing managed to keep lines running.
Choosing well requires more than finding the lowest price per unit. It means evaluating suppliers across several dimensions that don’t always show up on a spec sheet.
Know What You Actually Need Before You Start Talking to Suppliers
The first mistake most procurement teams make is approaching a semiconductor supplier before they have a clear picture of their own requirements. This puts the supplier in the position of defining the solution, which isn’t always in the buyer’s interest.
Before opening any conversations, nail down the following:
- Technical specifications: Voltage tolerances, operating temperature ranges, package type, process node, and any certifications required for your end market
- Volume and cadence: Annual unit requirements, order frequency, and whether demand is stable or seasonal – suppliers price and prioritize differently depending on how predictable your orders are
- Lead time requirements: How much buffer you carry and how quickly you need to respond to demand changes determines how important the supplier’s cycle time and inventory flexibility actually is to you
Going into supplier conversations with this defined gives you a basis for comparison and makes it harder for a sales pitch to substitute for a genuine fit.
Evaluate Manufacturing Capability and Quality Controls
Not all semiconductor supplier manufacture their own products. The industry includes integrated device manufacturers (IDMs) who design and fabricate their own chips, fabless companies that design chips but outsource fabrication to foundries, and distributors who carry inventory from multiple manufacturers.
For most buyers, the key manufacturing questions are:
- Where are the fabs located, and what does that mean for geopolitical exposure? Concentration in a single region – Taiwan, South Korea, or anywhere else – carries risk that diversification across suppliers can partially offset
- What quality certifications does the supplier hold, and how recently were they audited? IATF 16949 for automotive, ISO 9001 for general manufacturing, and JEDEC compliance for reliability testing are worth verifying rather than taking at face value
A supplier that’s reluctant to share quality documentation or audit results is telling you something important.
Look at Track Record During Constrained Periods
A semiconductor supplier’s behavior during normal market conditions tells you less than their behavior when supply is tight. The 2020 to 2022 shortage period created a natural experiment: some suppliers prioritized long-term customers and honored existing contracts; others allocated available inventory to whoever was willing to pay spot prices or simply couldn’t deliver at all.
If you’re evaluating a new supplier, ask directly how they managed allocation during that period. Talk to their existing customers if possible. References from companies in your industry who went through a shortage with that supplier are more informative than any sales presentation.
For suppliers you’re already using, your own history is the data. Look at on-time delivery rates over the last three to four years rather than just the most recent quarter. Supply chain performance has a way of reverting to its norm once a crisis passes.
Pricing Structure and Total Cost of Ownership
Price per unit is the starting point, not the endpoint. The actual cost of a semiconductor supply relationship includes a range of factors that don’t appear on the initial quote:
- Minimum order quantities: A low unit price paired with a high MOQ can result in significant carrying costs if your demand doesn’t absorb inventory quickly
- Pricing tiers and volume commitments: Some suppliers offer meaningful discounts at volume thresholds that are worth understanding before you negotiate
- Reel and packaging fees, obsolescence risk, and engineering change notifications: These administrative costs add up across a multi-year relationship and vary considerably by supplier
The cheapest supplier on paper is frequently not the cheapest supplier in practice. Building a total cost model that accounts for carrying costs, quality escapes, and the cost of supply disruptions gives a more accurate comparison.
Build in Redundancy From the Start
Single-source dependency on any critical component is a risk that tends to feel acceptable until it isn’t. For any semiconductor supplier that sits on your critical path, qualifying a second source during the product design phase is substantially easier than scrambling to qualify one under pressure when your primary supplier has a problem.
This doesn’t mean splitting every order equally between two suppliers. It means having a qualified alternative that can be ramped quickly if needed. That qualification process – testing, validation, approval – takes time measured in months, which is why waiting until a crisis to start it almost never works.
The goal isn’t to eliminate supplier concentration. It’s to ensure that no single relationship has the power to stop your production.
