Integrated quality concept
According to ISO 9000, Quality is the degree to which a set of inherent characteristics of an object fulfills requirements.
At X-FAB, we understand quality as an ongoing process that covers all the steps needed to develop, realize and maintain our technologies and services along their whole lifecycle. This process is tailored to the following key results:
- Robust design: Built-in robustness and its validation are essential objectives of technology development at X-FAB. Beyond this, we actively support our customers in achieving these objectives for their products as well.
- Reliable technology: Our technologies are created and qualified according to stringent criteria that cover wide-ranging application requirements in terms of performance, operating conditions and lifetime.
- Quality control: The achievement of quality objectives in manufacturing needs to be measurable in order to generate quantitative assessments as a basis for highly effective and efficient quality control.
- Manufacturing excellence: We control and continually improve both productivity and quality in order to achieve excellence in manufacturing with highest quality standards.
- Advanced product quality planning
Our technology development procedure is in line with the Advanced Product Quality Planning (APQP) process. It includes different stages and release levels with defined quality criteria.
- Risk mitigation and safe launch
Along all stages of our technology development projects, we focus on early risk identification and mitigation, supported by a comprehensive application of the Failure Mode and Effects Analysis (FMEA) and Six Sigma (6σ) approaches. This process is continued as new technologies are transferred from development to production. To secure the manufacturing ramp-up of new products, we offer dedicated safe launch programs and services.
- Quality assurance and monitoring
Already during the development of new technologies, based on the identified risks and determined risk mitigation strategies, we define, validate and implement appropriate measures and criteria for quality assurance and monitoring in manufacturing, such as:
- In-process inspections and measurements
- Statistical Process Control (SPC)
- Process Control Monitoring (PCM)
- Wafer Acceptance Testing (WAT)
- Outgoing inspections
- Fast Wafer Level Reliability (fWLR) monitoring and Reliability Conformance Testing (RCT)
The effectiveness and efficiency of these measures are continuously checked and optimized if necessary.
- Failure analysis and problem solving
To ensure fast learning from any quality failures that may occur in the development, qualification or manufacturing phase of a technology, comprehensive failure analytics capabilities are in place at our in-house failure analysis laboratories and in our network of proven external partners.
For further information, please download our X-FAB Failure Analysis Capabilities
Technical problems with the potential to affect quality need to be solved quickly, effectively and sustainably wherever they may occur. This requires the use of systematic and focused methods such as 8 Disciplines Problem Solving (8D), Plan-Do-Check-Act (PDCA) or Define-Measure-Analyze-Improve-Control (DMAIC). To ensure fluency in their application, these methods are key elements of our staff training programs. Lessons Learnt (LL) from successfully solved problems are directly recorded and actively shared throughout the company.
- Continual improvement and zero defects
Based on data and information collected during technology development and manufacturing as well as feedback from our customers, we achieve a steady enhancement of our competencies, capabilities and performance, resulting in continually improving quality.
Especially for automotive electronics, the aim for zero defects is of major importance, since it requires a consequent and consistent use of “best practices […] that are appropriate to drive to zero defects through the phases of process design, product design, production and product/manufacturing improvement” (AEC-Q004). Through a well-established zero defects mindset and framework, we turn innovative ideas into excellence in manufacturing.
- Process change management
To enable continual improvements and extensions of our manufacturing capacities and capabilities and to secure the longevity of our manufacturing processes, changes affecting materials, equipment, methods and technological/logistical aspects are necessary from time to time, which then need to be properly managed. The preparation, validation and implementation of process changes at X-FAB follow the Advanced Product Quality Planning (APQP) process and actively involve affected customers (if appropriate) in order to mitigate risks. We ensure a full traceability of relevant changes along the whole lifecycle of manufacturing processes.
- Multi-site manufacturing and consistent quality management
We have implemented and maintain a fully consistent quality management system across all our manufacturing sites (certified according to the IATF 16949 standard). This enables us to flexibly combine process capabilities and capacities at various sites in order to realize products with advanced functionalities.
- Reliability: Probability that a device will function without failure over a specified time period or amount of usage under stated conditions.
- Qualification: Process of demonstrating that an entity is capable of meeting or exceeding the specified requirements (JEDEC JEP148).
- Reliability qualification: Process of demonstrating that an entity is capable of meeting or exceeding the specified reliability requirements, usually by tests using accelerating conditions and proven models (JEDEC JEP148).
- Process and device reliability characterization
A comprehensive characterization of the reliability performance of technology elements, such as primitive devices, physical layers and functional IP, is part of our development procedure and provides the base for a quantitative description of the achievable reliability performance depending on product-specific mission profiles and failure criteria. Dedicated process reliability specification documents and an interactive lifetime simulator tool (RelXplorer) are accessible through our customer portal my X-FAB.
- Design for reliability and robustness
High manufacturability, reliability and robustness of our customers’ products are important to meet demanding quality objectives stably over a long period of time. That’s why we provide a variety of tools and contents to support our customers in achieving these requirements in product development and design, such as:
- Six Sigma process specification
- Monte Carlo simulation
- Lot-specific SPICE models
- Process corner models
- Process reliability specification
- Safe operating area check
- Design rule check
- Reliability design rules
- Reliability calculator (RelXplorer)
Our embeddable IP solutions for digital and memory applications are designed for manufacturability, reliability and robustness. They also include Design for Test (DfT) and Design for Analysis (DfA) features.
Many of these items are accessible through our customer portal my X-FAB.
- Reliability test methods
The methods we use in Reliability Qualification Testing (RQT) and Reliability Conformance Testing (RCT) follow industry standards and are supplemented by internal know-how. The following standards for reliability test methods in particular are considered at X-FAB, as far as applicable:
- JEDEC JEP001: Foundry Process Qualification Guidelines (Wafer Fabrication Manufacturing Sites)
- AEC-Q100: Failure Mechanism Based Stress Test Qualification for Integrated Circuits
- AEC-Q103: Failure Mechanism Based Stress Test Qualification for Sensors in Automotive Applications
- Robustness validation
Our technology qualification procedure goes beyond the demonstration of minimum reliability requirements, following the Robustness Validation approach, which is based on knowledge about reliability failure mechanisms. This includes stress testing to failure, analysis of obtained failures, determination of physics-of-failure and acceleration models as well as the evaluation of impacts of manufacturing process variability on functional and reliability performance (robustness margin analysis).
