The semiconductor industry has been closely related to the military and aviation industries for many years. Military and government projects have accelerated the development of technology and rapidly improved the quality and reliability of components. Over the years, the government has been closely monitoring the activities of arms dealers through the Department of Defense Logistics (DLA), the Columbus Defense Supply Center (DSCC), and the Joint Navy and Navy Project (JNA). The above-mentioned government agencies guide the work of semiconductor manufacturers through a series of strict absolute specifications, and any changes in component design, construction or process management must be approved by the relevant departments. The relevant specifications have detailed product compliance and regulatory details, and are submitted to the relevant government authorities for approval before implementation, and no changes are allowed in the relevant details.

In the 1980s, the Department of Defense (DOD) recognized that the business sector is increasingly driving technology, and existing systems are no longer able to continue to function. In addition, coupled with the significant increase in equipment complexity, the cost of qualifying certifications, which are often repetitive, is increasing, which has led to the implementation of the Qualified Manufacturers List (QML) program. According to the QML program, the DSCC has certified manufacturers to verify the quality and reliability of the design, certification, and manufacturing of components such as integrated circuits (ICs). QML IC manufacturers use a range of existing specifications as a guide to design, process, and compliance. However, the focus of its work is shifted to the performance of the product by confirming that the product meets the specifications. The DSCC and DoD allow QML manufacturers' Technical Review Boards (TRBs) to determine which compliance specifications and inspection methods are required to ensure the quality and reliability of the final product. In this way, standard existing components can be used to replace customer specifications and still ensure that the product meets the application requirements.
As far as the environment is concerned, today's automotive electronics industry is very similar to the military electronics industry 10 years ago. Customer specific requirements are gradually increasing and become a supplement to industry standards. Customer specifications are rules, not the exceptions, and a car customer often has more than one design for a vendor's device. The role of existing infrastructure is not only to address general issues and to improve supplier relationships, but to play a more important role in the development and management of relevant documents.
Automotive customers typically have specific requirements for applications or operations that are reflected in the customer's printed materials and general specifications. Equipment specifications often do not fully match the IC supplier's standard products, so a technical dialogue is required between the two parties to revise the printed materials. Standards for compliance are usually based on AEC Q-100. The resulting compliance report (often referred to as the production part approval process, or PPAP) is required to be approved by the customer prior to production. These procedures often result in unnecessary complication of procurement work. Some standard, off-the-shelf automotive products have already met application performance requirements, and their order-to-shipment time is very short, so the above situation is more complicated for these products.
Customer compliance standards and controls are guaranteed under certain circumstances (eg for applications where safety is particularly important) to achieve the automotive industry's goals: highest quality and reliability, and lowest cost, while the entire industry should Adhere to the principles of manufacturer's qualified specifications.
Standard off-the-shelf solution
Texas Instruments defines its standard product portfolio based on QML's and automotive supplier experience to meet the needs of automotive customers to purchase off-the-shelf solutions. The product line combines standards for meeting the best business practices and the AEC Q-100 as a guiding principle. This allows it to respond quickly to customer needs while ensuring that products are delivered to meet the quality and reliability requirements of high-standard automotive applications. At the same time, automotive customers must form partnerships with selected suppliers to minimize unnecessary compliance certification and should be subject to supplier compliance standards based on supplier expertise and customer needs.
Quality system
To be successful, IC suppliers must establish a quality system that ensures they are fully aware of customer needs and that customer requirements are expressed in detail throughout the organization. The standards organization has long recognized that the hierarchical system shown in Figure 1 is optimal. There should be a top-level document, the Quality System Manual, to clarify the broad requirements. This is often referred to as the "what to do" specification. This top quality document then advances to the next level of specifications and standards covering all business practices, from design, wafer fabrication, assembly, testing, quality compliance to customer support and other aspects of product development. These are often referred to as "how to" specifications. As part of the quality system's internal checks and balances, members who are familiar with automotive customer requirements must occupy permanent positions in the entire door team and manage the regulatory system. In this way we can ensure that the quality system and specifications can meet the requirements of automotive customers.
Quality and reliability
Automotive customers propose mandatory specifications to suppliers that meet specific performance requirements. In order to ensure that a particular device or family of devices meets the needs of the customer, the organization must be closely linked to the responsible operator, including device design, wafer fabrication, assembly/test, and application engineering.
In order to ensure the best quality and reliability of the device over extended temperature ranges and in a variety of automotive environments, we need additional evaluation in the following areas:
Semiconductor reliability and electromigration inspection of the target package under the highest recommended operating conditions;
Detect electrical characteristics at different temperatures;
Determine the performance of the package material set over the extended temperature range (eg, some mold compounds are not suitable for operation over extended temperature ranges).
Different levels of quality compliance and reliability testing should be performed. Any new process or device technology should be subject to extensive compliance certification, and existing processes or technologies should be adjusted to meet specific equipment requirements in addition to similar compliance standards. as shown in picture 2.
Various quality and reliability tests should be performed after initial certification. At the wafer fab, we should perform wafer level reliability testing to ensure that the fab's process is fully under control and can be produced according to wafer fabrication specifications.
We should perform package-related testing at the assembly site to ensure that the assembly process is under control and that reliable devices can be fabricated. In addition, external failure rate (EFR) and inherent failure rate (IFR) life test should be performed periodically.
Customer Support
Automotive customers may require additional support even if they purchase standard equipment. Regardless of whether the automotive equipment is modified to require customer approval or a standard off-the-shelf solution, our service commitment to automotive customers is the same. Automotive customers receive the following support for standard products:
Product choice
Application support
180 days advance notice of process changes
Longer product life end purchase support
Confirm customer equipment failure within 24 hours after receiving the faulty device
Suppress the problem within 24 hours after confirming the product problem
Identify the root cause of the problem and take corrective action as appropriate (8D mode)
Car FA support
In conclusion
By partnering with selected suppliers and using standard off-the-shelf components wherever possible, automotive customers can reduce costs and accelerate product delivery. We can shorten the internal design cycle by relying on suppliers to provide off-the-shelf solutions that meet the needs of our customers.
