Semiconductor and advanced electronics represents the largest single cluster of new manufacturing investment in Singapore. Wafer fab expansions, OSAT capacity growth, and equipment manufacturing investments make up an estimated 35 to 40 per cent of the new manufacturing jobs committed through EDB investment announcements, according to Corestaff's analysis of EDB published data. Singapore's RIE2030 plan commits S$37 billion to key advanced manufacturing areas including semiconductors as the anchor cluster, according to EDB.
For the companies that make up this ecosystem, the liability exposure is one that most general insurance programmes are not designed to address. And the gap is not at the edges of the exposure. It is at the centre of it.
The structure of the semiconductor supply chain and where liability concentrates
The semiconductor supply chain in Singapore spans several distinct categories of company, each with a different position in the value chain and a different liability profile.
Wafer fabrication facilities produce silicon wafers with integrated circuits etched onto them. When a wafer lot produces chips that do not meet the electrical specification, the claim flows from the fabless customer back to the fab for the cost of the failed lot and any downstream consequences.
Outsourced Semiconductor Assembly and Test, or OSAT, firms package and test finished semiconductor devices. A packaging or testing error that causes a finished device to fail creates a claim against the OSAT firm for the cost of the failed devices and any production disruption at the customer.
Equipment manufacturers produce the precision tools used in wafer fabrication, packaging, and testing. When a piece of semiconductor equipment underperforms its specification, the fab or OSAT firm that bought it may claim for the cost of production losses attributable to the equipment's underperformance.
Support services firms provide metrology, inspection, chemicals, gases, and other inputs into the semiconductor manufacturing process. A contaminated process chemical that ruins a wafer lot, or a metrology error that causes a production run to proceed with incorrect parameters, creates a claim against the supplier for the resulting production loss.
In each of these supply chain positions, the most significant claims are not claims for bodily injury or property damage. They are claims for financial loss: failed lots, production holds, missed delivery commitments, and the contractual penalties that flow through the supply chain when a semiconductor programme is delayed.
Why standard product liability misses the most significant semiconductor claims
Standard product liability insurance responds to claims for bodily injury or property damage caused by a defective product. For a semiconductor supply chain company, the policy responds if a component causes physical harm to a person or causes tangible damage to another piece of physical property.
But the most common and in aggregate most financially significant claims in the semiconductor supply chain do not involve physical harm. A wafer lot that fails its parametric test and must be scrapped represents a financial loss to the customer. A packaged device that fails its final test and cannot be shipped represents a financial loss at the OSAT stage. A piece of equipment that produces wafers at 95 per cent of its specified yield rather than 99 per cent represents a financial loss over the course of a production run that may extend for months or years.
None of these are bodily injury claims. None are property damage claims in the conventional sense. They are all economic loss claims arising from a product or service that failed to perform as specified. Standard product liability insurance does not respond to them.
Manufacturers Errors and Omissions insurance covers claims for economic loss arising from a product that failed to perform as specified or a service that was not delivered as contracted. For companies at every stage of the semiconductor supply chain, E&O cover is the policy that addresses the claims most likely to arrive.
The yield and specification gap: how semiconductor E&O claims arise
In the semiconductor industry, yield is everything. A fab that achieves 98 per cent yield on a given process node is performing well. A fab that achieves 94 per cent yield on the same node has a problem, and the problem has a financial consequence for the customer whose wafer lot produced fewer conforming chips than the contracted specification.
For an OSAT firm, the equivalent is test yield: the proportion of packaged devices that pass final electrical test. A test yield shortfall against the contracted specification creates a claim for the shortfall in conforming devices.
For equipment manufacturers, the yield implication is embedded in the equipment specification itself. A deposition tool that deposits films at a thickness uniformity outside its contracted specification will affect every wafer processed on that tool, and the cumulative financial consequence can be substantial over a production programme.
These are E&O claims in structure even when they arise from product characteristics rather than professional advice. The product did not perform as specified. The customer suffered a financial loss as a result. The E&O policy responds.
The cyber dimension in semiconductor manufacturing
Semiconductor manufacturing is one of the most data-intensive manufacturing environments in existence. Process recipes for wafer fabrication contain proprietary parameters representing years of process development. Yield data, equipment maintenance records, and quality test results are generated continuously and held on networked systems. Design rule files, mask data, and chip layout files are exchanged between the fab and the fabless customer under confidentiality obligations.
For Singapore semiconductor manufacturers, the cyber exposure operates at three levels.
Operational technology risk is the risk that a cyber attack affects the computer systems controlling the manufacturing equipment. A compromised process controller that modifies a recipe parameter can affect an entire wafer lot before the deviation is detected. A ransomware attack on the manufacturing execution system can halt production across the facility.
Intellectual property risk is the risk that a cyber attack or insider event exposes proprietary process data or customer design data. For a Singapore fab holding chip design files for multiple fabless customers, a data breach affecting those files creates liability to the affected customers.
Supply chain cyber risk is the risk that a cyber attack on a supplier, equipment vendor, or process materials provider propagates into the Singapore manufacturer's systems through the connected supply chain. Semiconductor supply chains are deeply interconnected, and a breach at a supplier can have consequences at the manufacturer level even when the manufacturer's own systems were not directly compromised.
Cyber insurance for a Singapore semiconductor manufacturer needs to address all three levels: OT risk in the manufacturing environment, IP and data security risk in the customer relationship, and supply chain cyber risk from connected third parties.
What to confirm in the insurance programme
For a Singapore semiconductor company at any stage of the value chain reviewing its insurance programme, three questions are worth addressing specifically.
Does the product liability policy cover economic loss claims from customers when products fail to meet yield or specification requirements? If the policy covers only bodily injury and physical property damage, the programme has a gap for the most common category of semiconductor supply chain claim.
Does the programme include Manufacturers E&O cover that specifically addresses yield shortfalls, specification non-conformance, and equipment underperformance? The definition of covered losses in an E&O policy matters, and confirming that yield and specification claims are within scope is a practical step.
Does the cyber policy cover operational technology systems in the wafer fab or OSAT environment, as well as the intellectual property and customer design data held in connected systems?
