Why Wafer Bumps Are Suddenly So Important


Wafer bumps need to be uniform in height to facilitate subsequent manufacturing steps, but a push for 100% inspection in packaging in mission-critical markets is putting a strain on existing measurement technologies. Bump co-planarity is essentially a measure of flatness. Specifically, it measures the variation in bump height, which may have a target, for example, of about 100 microns. As a ... » read more

Week In Review: Manufacturing, Test


Chipmakers Intel has re-entered the foundry business after a failed attempt several years ago. In its new efforts, Intel is establishing a new standalone business unit called Intel Foundry Services. As part of those efforts, Intel has announced plans to build two new fabs in Arizona. This build-out represents an investment of approximately $20 billion. “INTC hosted a strategy update with ... » read more

Defect Challenges Grow For IC Packaging


Several vendors are ramping up new inspection equipment based on infrared, optical, and X-ray technologies in an effort to reduce defects in current and future IC packages. While all of these technologies are necessary, they also are complementary. No one tool can meet all defect inspection requirements. As a result, packaging vendors may need to buy more and different tools. For years, p... » read more

Week In Review: Manufacturing, Test


Chipmakers At its Architecture Day this week, Intel disclosed its roadmap for the company’s next-generation microprocessors, graphics chips, FPGAs and other products. As part of the event, Intel announced some new enhancements for its existing 10nm finFET technology. Basically, it’s a mid-life kicker for the technology. Intel calls it the 10nm SuperFin technology, which is a redefinitio... » read more

Better Analytics Needed For Assembly


Package equipment sensors, newer inspection techniques, and analytics enable quality and yield improvement, but all of those will require a bigger investment on the part of assembly houses. That's easier said than done. Assembly operations long have operated on thin profit margins because their tasks were considered easy to manage. Much has changed over the past several years, however. The r... » read more

Finding Defects In IC Packages


Several equipment makers are ramping up new inspection equipment to address the growing defect challenges in IC packaging. At one time, finding defects in packaging was relatively straightforward. But as packaging becomes more complex, and as it is used in markets where reliability is critical, finding defects is both more difficult and more important. This has prompted the development of a ... » read more
