Scanning an entire 300mm wafer with a single electron beam can take many hours or even days, far exceeding the strict time budgets of modern fabs. “If you want to catch the defects in the fabrication ...

As 3D packages become increasingly complex, so do the challenges in identifying defects within vertically stacked, multiple layers. Focus is now shifting to methods of non-destructive testing such as ...

WALTHAM, Mass.--(BUSINESS WIRE)--Thermo Fisher Scientific Inc., the world leader in serving science, introduced a groundbreaking transmission electron microscope to a packed room of attendees at ...

PVA TePla OKOS, a Virginia-based manufacturer of industrial ultrasonic non-destructive (NDT) systems, claims to have a solution based on scanning acoustic microscopy (SAM). A non-invasive and ...

New acoustic microscopy techniques, such as scanning acoustic microscopy (SAM) and time-of-flight acoustic microscopy (TOF-AM), enable the detection and characterization of very small defects, ...

Figure 6: Scanning acoustic microscopy images of the AMB side and the baseplate side after thermal cycling. The area of each of the substrates is approximately 1,000 mm 2. TCT condition: –55°C/150°C ...

Thus, researchers looked to optical microscopy for more efficient methods that might also work well in the acoustic domain. In optical microscopy, the alternative to scanning is variously called ...

The SMM is very similar to scanning capacitance microscopy (SCM) in terms of the dopant density measurements. However, the SMM provides a broader range of measurements because it does not rely ...

New developments in scanning acoustic microscopy, also known as ultrasonic non-destructive testing, position the quality inspection technology for use by manufacturers of all sizes. Most automated ...
