EN 61943:1999

• Abstract:

  Defines how to apply the principles and requirements given in IEC 61739 to monolithic integrated circuits. The standard is applicable to those manufacturers of integrated circuits (ICs) who apply for manufacturing line approval. The objective is to establish consistency in the requirements used by manufacturers and auditors for techniques related to integrated circuit manufacturing. Each manufacturer may use his own methods for satisfying the requirements of this standard, provided that the required level of control in the manufacturing line is reached.

Overview

EN 61943:1999 - Integrated circuits: Manufacturing line approval application guideline (CLC) provides guidance for applying the principles and requirements given in IEC 61739 to monolithic integrated circuits (ICs). The standard is intended for IC manufacturers applying for manufacturing line approval and aims to establish consistency between manufacturers and auditors in evaluating techniques and controls used in IC fabrication. Manufacturers may use their own methods provided the required level of control on the manufacturing line is achieved.

Key topics and requirements

EN 61943 focuses on practical elements needed to demonstrate that an IC manufacturing line meets approval criteria. Key topics typically addressed include:

• Manufacturing line control and qualification - showing consistent, repeatable process control across the line.
• Process documentation and records - policies for maintaining process flows, change control and historical evidence for audits.
• Traceability and lot control - linking materials, wafers, and devices through the fabrication and test flow.
• Equipment calibration and maintenance - demonstrating equipment is maintained and calibrated to support process stability.
• Contamination and environmental controls - requirements for contamination prevention, cleanroom practices and monitoring.
• Personnel competency and training - demonstrating appropriate staff qualifications and training records for critical roles.
• Auditability and evidence for approval - preparing objective evidence and metrics that auditors can use when granting manufacturing line approval.

(EN 61943 is aligned with IEC 61943:1999 and references the principles of IEC 61739 for application to monolithic ICs.)

Applications - who uses this standard

EN 61943 is used by:

• IC manufacturers preparing applications for manufacturing line approval or internal qualification.
• Quality and compliance managers who need consistent criteria for process controls and audit evidence.
• Process and fab engineers implementing controls, traceability and documentation to meet approval expectations.
• Third‑party auditors and certification bodies assessing readiness and consistency of IC manufacturing lines.
• Supply chain and procurement teams evaluating supplier manufacturing capability and approval status.

Practical uses include preparing approval dossiers, structuring internal audits, aligning supplier assessments, and demonstrating process maturity to customers or regulators.
