ISO 9001
The general international standard for quality management systems, specifying requirements for documented processes, customer focus, risk based thinking, internal audit and management review that an organisation must meet to be certified.

Notes
It certifies that a company follows its own defined processes, which is necessary but far from sufficient for semiconductor quality.
Overview
ISO 9001 is the international standard that sets the requirements for a quality management system: the organised way a company plans, runs, checks and improves its work so that it reliably meets customer and regulatory requirements. It is the only standard in the ISO 9000 family that organisations can be certified against, and it applies to any sector and size. The sixth edition, ISO 9001:2026, was published in September 2026 and replaced the 2015 edition.
How it works
The standard rests on quality management principles: customer focus, leadership, engagement of people, the process approach, improvement, evidence based decision making and relationship management. Its requirements cover understanding the organisation's context, leadership commitment, planning for risks and opportunities, resources and competence, control of products and services, monitoring and measurement, internal audit, management review and corrective action.
ISO itself certifies no one. Independent certification bodies, accredited by national accreditation bodies, audit an organisation and issue a certificate for a stated scope. Certification is pass or fail, major nonconformities must be corrected first, and certificates are usually renewed every three years with audits in between.
The 2026 edition keeps the framework but aims to make the requirements easier to understand, puts more weight on quality culture and leadership, treats risks and opportunities separately, and aligns more closely with other ISO management system standards. Certified organisations move from the 2015 edition over a transition period.
Examples
- A fabless chip company certified to ISO 9001 for design, product engineering and supply chain management, with manufacturing at certified partners.
- An internal audit that finds test program changes released without the required review, leading to corrective action.
- A materials supplier presenting its ISO 9001 certificate as a basic requirement when qualifying with fab customers.
- A certified company planning its move from the 2015 edition to ISO 9001:2026 before its next recertification audit.
Why it matters
ISO 9001 certification is a common baseline that customers expect across the semiconductor supply chain, from materials and equipment vendors to chip companies, assembly and test subcontractors and distributors. Quality systems managers, internal auditors and process owners maintain it day to day, and sector schemes build on it: the automotive standard IATF 16949 is applied together with ISO 9001, and the IATF is preparing a second edition of its own.
In the chip lifecycle, ISO 9001 underpins how a company controls design and development, purchasing, manufacturing, test, release and the handling of complaints, so it touches every stage from product definition to end of life.
It matters most to: Audit and Certification Coordinator, Quality Director, Semiconductor Manufacturing, Quality Management System Lead Auditor, Quality Systems Engineer, Quality Systems Manager
Common confusions
- Not the same as IATF 16949
- IATF 16949 is the automotive sector standard that adds requirements on top of ISO 9001. It is applied together with ISO 9001 rather than replacing it. ISO 9001 vs IATF 16949
- Not the same as ISO 9000
- ISO 9000 is the companion standard covering fundamentals and vocabulary. Organisations are certified to ISO 9001, not to ISO 9000.
- Not the same as product certification
- An ISO 9001 certificate says the organisation runs a conforming management system. It does not certify that any particular product meets its specification.
