These defects can develop over time, leading to Entegris proposes a New Collaborative Approach to examine failures that can result in safety hazards and expensive recalls. the role of chemical, air, and gas contamination in the formation of defects undiscovered in the semiconductor manufacturing TOWARDS THE PPB LEVEL process. Electronic defects are already a costly problem, but a number of factors could make them a much more significant problem in the future. The value of electronic components in vehicles is rising and largely attributable to digital control and comfort systems, advanced driver assistance systems (ADAS), and the continued development of fully autonomous vehicles. As vehicle cost increases, so does the expectation of “excellence” among buyers, as drivers and passengers become more reliant on embedded systems to guide and control their travels. With electronics increasingly incorporated into safety systems and with the advent of self-driving vehicles, electronic system failures can be potentially life-threatening. This will intensify demand for recalls when problems arise. And as the usage patterns of vehicles increases, there will be more time for costly latent defects to develop. According to Electroiq*, a typical vehicle today contains between 5000 and 8000 microchips (chips). A manufacturer producing 25,000 vehicles per day with a parts-per-million (PPM) chip failure rate may produce 125 vehicles per day with lurking chip Read the paper to learn more quality issues. If nothing changes, that number will multiply as www.entegris.com/automotive more electronics are added to vehicles. In order to overcome these challenges, chipmakers will need to find ways to either economically identify or prevent the creation of less reliable chips and remove them from the supply chain * Process Watch: The Automotive Problem with Semiconductors.
