Measuring Reflective Surfaces


Manufacturers are adopting automated optical inspection (AOI) systems based on phase shift profilometry (PSP) for applications in advanced packaging processes. Many of these processes use front end-like techniques to create connections among die within a package and from the packaged die to the outside world. The technique offers fast, precise measurements of the 10µm to 100µm features that a... » read more

NanoResolution MRS Sensor Delivers Fast, Precise 3D Inspection And Measurement For Advanced Semiconductor Packaging Applications


The semiconductor packaging industry continues to advance, with new designs adding more layers, finer features and more I/O channels to achieve faster connections, higher bandwidth and lower power consumption. As packaging technologies have evolved, manufacturers have adapted old processes and adopted new processes to connect chips to each other and to the outside world. Often these new process... » read more

The Need for Speed


We’ve previously identified the convergence occurring between surface mount technologies (SMT), used to connect packaged semiconductor devices on printed circuit boards, and advanced packaging (AP) technologies, in which connections between the semiconductor devices and to the outside world are incorporated in the packaging process using front-end-like, wafer-or panel-based manufacturing proc... » 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

Extending 3D MRS Sensor Technology To Address Challenging Measurement And Inspection Applications


There is an increasing need for highly accurate 3D inspection and measurement capabilities for applications in SMT, semiconductor and metrology markets. 3D Multiple Reflection Suppression (MRS) sensor technology has been effectively combined with Automated Optical Inspection for several years and is now being utilized for many SPI applications such as microelectronics and sub-100-micron sold... » read more
