Yield Is Top Issue For MicroLEDs


MicroLED display makers are marching toward commercialization, with products such as Samsung’s The Wall TV and Apple’s smart watch expected to be in volume production next year or in 2024. These tiny illuminators are the hot new technology in the display world, enabling higher pixel density, better contrast, lower power consumption, and higher luminance in direct sunlight — while consu... » 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

Speeding Up E-beam Inspection


Wafer inspection, the science of finding killer defects in chips, is reaching a critical juncture. Optical inspection, the workhorse technology in the fab, is being stretched to the limit at advanced nodes. And e-beam inspection can find tiny defects, but it remains slow in terms of throughput. So to fill the gap, the industry has been working on a new class of multiple beam e-beam inspectio... » read more

Wanted: Multi-beam E-Beam Inspection


The IC industry is making a giant leap from planar devices to a range of next-generation architectures, such as 3D NAND and finFETs. But it’s taking longer than expected to ramp up these new technologies in the market. And the challenges are expected to mount for the next round of chips. It’s difficult to pinpoint the exact issues with 3D NAND and finFETs. On the manufacturing front alo... » read more
