Improvement Of Dopant Concentration Control With Acoustic Control System For B-SiGe Epitaxy Deposition


Currently, SiGe-B epitaxy is a leading technology to induce strain in PMOS channel and improve the hole mobility to achieve better device performance. In practice, we observe that the device performance strongly depends on the dopant concentration, especially boron concentration. It is shown that the Acoustic Control System [ACS] is able to actively respond to instantaneous variations of incomi... » read more

Inspection, Metrology Challenges Grow For SiC


Inspection and metrology are becoming more critical in the silicon carbide (SiC) industry amid a pressing need to find problematic defects in current and future SiC devices. Finding defects always has been a challenging task for SiC devices. But it’s becoming more imperative to find killer defects and reduce them as SiC device vendors begin to expand their production for the next wave of a... » read more

MicroLEDs: The Next Revolution In Displays?


Flat-panel display technology is exploding on several fronts as more screens are required for more devices. But one type of display is generating an enormous amount of buzz in the market—microLEDs. Dozens of companies are working on micro-light emitting diodes (microLEDs), a technology that promises to provide better and brighter displays than current solutions in the market. Apple, Facebo... » read more

Mixed Outlook For Silicon Wafer Biz


After a period of record growth, the silicon wafer industry is off to a slow start in 2019 and facing a mixed outlook. Generally, 200mm silicon wafer supply remains tight. But demand for 300mm silicon wafers is cooling off in some segments, causing supply to move toward equilibrium after a period of shortages. On average, though, silicon wafer prices continue to rise despite the slowdown. ... » read more

Variation At 10/7nm


Klaus Schuegraf, vice president of new products and solutions at PDF Solutions, explains why variability is a growing challenge at advanced nodes, why middle of line is now one of the big problem areas, and what happens when a via is misaligned due to a small process variation. https://youtu.be/jQfggOnxZJQ » read more

Where Is Selective Deposition?


For years, the industry has been working on an advanced technology called area-selective deposition for chip production at 5nm and beyond. Area-selective deposition, an advanced self-aligned patterning technique, is still in R&D amid a slew of challenges with the technology. But the more advanced forms of technology are beginning to make some progress, possibly inching closer from the la... » read more

What Happened To DSA?


Directed self-assembly (DSA) was until recently a rising star in the next-generation lithography (NGL) landscape, but the technology has recently lost some of its luster, if not its momentum. So what happened? Nearly five years ago, an obscure patterning technology called [gettech id="31046" t_name="DSA"] burst onto the scene and began to generate momentum in the industry. At about that t... » read more
