Achieving Zero Defect Manufacturing Part 3: Prevention Of Defects

The concept of zero defect manufacturing has been around for decades, arising first in the aerospace and defense industry. Since then, this manufacturing approach has been adopted by the automotive industry, and it has only grown in importance as the sector transitions to electric vehicles. Given the role semiconductors play in today’s vehicles, and will play in the future, it is no surprise the industry has adopted a zero defect approach.

However, the quest for zero defect manufacturing goes well beyond the aerospace, defense, and automotive industries. Many companies that have started or are planning digital transformations are pursuing zero defect manufacturing. Accomplishing this requires using data from a wide range of sources, including materials, products, processes, factory subsystems, and equipment. When all of this data is properly integrated, and fabs are able to take complete advantage of the analytics from their monitoring systems, the goal of a zero defect manufacturing environment is achievable.

Before we go any further, we should get one thing out of the way: zero defect manufacturing does not promise zero defects. It is a commitment to properly identifying defects and sources, giving manufacturers the opportunity to detect dormant failures early on and make proactive corrections.
