Reticle Inspection And Metrology


Pattern defects and contamination on a reticle can cause yield issues in every die of every wafer printed. We take it for granted today, but it started out with people looking through a microscope and manually scrolling back and forth looking for defects on photomasks that originally were hand cut, and later on made by machines. Fast forward to the present and we're able to find the equivale... » read more

Flash Dance For Inspection And Metrology


Chipmakers are moving from planar technology to an assortment of 3D-like architectures, such as 3D NAND and finFETs For these devices, chipmakers face a multitude of challenges in the fab. But one surprising and oft-forgotten technology is emerging as perhaps the biggest challenge in both logic and memory—process control. Process control includes metrology and wafer inspection. Metrolo... » read more

Manufacturing Bits: April 14


Monster waves of light The FOM Institute AMOLF has observed what researchers call monster waves of light. In this phenomenon, monster waves of light appear from nowhere and then disappear again. Researchers have shown that it is possible to influence the probability of this phenomenon. As a result, the technology could lead to faster telecommunication systems or more sensitive sensors, acco... » read more

Searching For 3D Metrology


In the previous decade, chipmakers made a bold but necessary decision to select the [getkc id="185" kc_name="finFET"] as the next transistor architecture for the IC industry. Over time, though, chipmakers discovered that the finFET would present some challenges in the fab. Deposition, etch and lithography were the obvious hurdles, but chipmakers also saw a big gap in metrology. In fact,... » read more

Manufacturing Bits: Feb. 24


EUV progress report At the SPIE Advanced Lithography conference in San Jose, Calif., ASML Holding said that one customer, Taiwan Semiconductor Manufacturing Co. Ltd. (TSMC), has exposed more than 1,000 wafers on an NXE:3300B EUV system in a single day. This is one step towards the insertion of EUV lithography in volume production. During a recent test run on the system, TSMC exposed 1,022 w... » read more

All Together Now!


Consolidation is changing the face of our industry. It is tempting to think that a narrower more consolidated industry is easier to navigate and might require less facilitated coordination and collaboration. However, it turns out the reverse is true. With fewer, but much bigger companies, the bets become exponentially bigger.  At the same time technical challenges — such as advanced tra... » read more

Gaps In Metrology Could Impact Yield


For some time, chipmakers have been developing new and complex chip architectures, such as 3D NAND, finFETs and stacked die. But manufacturing these types of chips is no simple task. It requires a robust fab flow to enable new IC designs with good yields. In fact, yield is becoming a more critical part of the flow. Yield is a broad term that means different things to different parts of the ... » read more

Blog Review: April 2


Mentor’s Nazita Saye compares roadway roundabouts to networked systems. One roundabout works fine, but add in a bunch of them and you have a massive traffic jam. How many roundabouts are in your design? Cadence’s Richard Goering interviews Stan Kroliskoski, chair of the IEEE Design Automation Standards Committee, about four working groups on EDA standards and what’s ahead. Speaking ... » read more

Challenges Mount In Inspection And Metrology


Chipmakers are moving full speed ahead toward smaller process nodes, thereby driving up the costs and complexities in chip manufacturing. The migrations also are putting enormous stress on nearly all points of the fab flow, including a critical but unsung part of the business—process control. Process control involves 20 or so different segments in the inspection and metrology arena. Genera... » read more

Manufacturing Bits: Aug. 27


Growing tubes Single-wall carbon nanotubes could one day be used in electronics, optoelectronics, biomedical imaging and other applications. But the synthesis of nanotubes with defined chiralities has been a stumbling block. A chiral molecule is a molecule that has a non-superposable mirror image. The University of Southern California has shown that chirality-pure short nanotubes can be use... » read more
