Overview
IEC 60748-21:1997 is an international standard developed by the International Electrotechnical Commission (IEC) specifically for semiconductor devices, focusing on film integrated circuits (ICs) and hybrid film integrated circuits. This sectional specification serves as a technical framework aimed at ensuring quality through qualification approval procedures for both catalogue and custom-built film IC products. The standard defines preferred values for ratings and characteristics, selects appropriate tests and measurement methods, and outlines general performance and environmental test requirements.
As a sectional specification, IEC 60748-21 provides essential guidelines to be incorporated within detailed product specifications, helping manufacturers and stakeholders maintain consistent quality and reliability standards in the production and assessment of film and hybrid film ICs.
Key Topics
-
Scope and Application
Applies to film integrated circuits and hybrid film integrated circuits manufactured as catalogue items or custom designs where quality is assessed by qualification approval.
-
Preferred Characteristics and Ratings
Establishes preferred values for operational limits and physical characteristics of film ICs to ensure standardized quality. These values guide both manufacturers and testers in assessing device performance.
-
Qualification Approval Procedures
Describes structured methods to qualify product batches through rigorous testing, including environmental and electrical performance tests. This approval procedure ensures product reliability before broad market release.
-
Testing and Measurement Methods
Provides comprehensive test schedules and methodologies including environmental severity levels and acceptance criteria aligned with industry best practices, ensuring consistency in evaluation.
-
Compliance and Quality Control Levels
Details various assessment levels, criteria for resubmission of rejected lots, and quality control inspections to enforce ongoing compliance with the qualification requirements.
-
Manufacturing Considerations
Covers scenarios involving manufacturing stages in factories located in countries that are not IEC members, introducing procedural adjustments for qualification continuity in global supply chains.
Applications
IEC 60748-21 is highly relevant for:
- Semiconductor Manufacturers producing film and hybrid film integrated circuits aiming to achieve international quality certification.
- Quality Assurance Teams requiring a standardized framework to conduct qualification tests and ensure product reliability.
- Product Designers and Engineers developing custom or catalogue film IC products and needing precise guidelines for specification drafting and testing.
- Supply Chain Managers overseeing manufacturing and quality processes across different regions and ensuring compliance with global standards.
- Electronic Component Distributors and Buyers seeking assurance of product integrity through IEC qualification approval marks.
The standard's focus on qualification approval helps reduce product failures, optimize manufacturing reliability, and streamline market acceptance globally, making it indispensable for semiconductor device quality assurance and standardization.
