Litho Roadmap Remains Cloudy


By Mark LaPedus For some time, the lithography roadmap has been cloudy. Optical lithography has extended much further than expected. And delays with the various next-generation lithography (NGL) technologies have forced the industry to re-write the roadmap on multiple occasions. Today, there is more uncertainty than ever in lithography. Until recently, for example, leading-edge logic chipma... » read more

Keeping EUV Cool


It’s been clear for a long time that EUV lithography sources will be fairly inefficient. The laser-produced plasma (LPP) source concept involves heating a droplet of metallic tin with a high-powered laser to produce a plasma. Only a fraction of the energy of the laser will be converted to light, rather than heat, and less than 1% of the light emitted by the plasma will be at EUV wavelengths. ... » read more

What’s After 3D NAND?


By Mark LaPedus Planar NAND flash memory is on its last scaling legs, with 3D NAND set to become the successor to the ubiquitous 2D technology. Samsung Electronics, for one, already has begun shipping the industry’s first 3D NAND device, a 24-level, 128-gigabit chip. In addition, Micron and SK Hynix shortly will ship their respective 3D NAND devices. But the Toshiba-SanDisk duo are the lo... » read more

450mm Is On Its Way!


By Adrienne Downey Intel finally has taken the big plunge into 450mm manufacturing with the announcement of the start of construction of fab D1X Module 2. The company plans to spend $2 billion on construction of the new development fab this year alone. Its twin fab, Module 1, is 450mm-compatible, but will begin production later this year as a 300mm fab running a 14nm process technology. Intel�... » read more

Japan: Latest Investment Activities


By Dan Tracy and Yoichiro Ando Restructuring and consolidation has led to a new focus for the semiconductor manufacturers in Japan. As a result, the semiconductor equipment market in Japan will experience double-digit growth in both 2013 and 2014, driven by higher spending for memory production and in spending increases planned for the manufacturing of power semiconductors and “More than Moo... » read more

The Week In Review: July 22


By Mark LaPedus ASML Holding has been under pressure to bring extreme ultraviolet (EUV) lithography into mass production. EUV is still delayed. Now, in their latest roadmaps, leading-edge chipmakers are counting on ASML’s 300mm EUV scanner for insertion at the 10nm node. Yet, at the same time, ASML also is working on a 450mm version of the EUV tool. “EUV (on 300mm) is a higher priority th... » read more

Changes And Challenges


At 130nm, the shift to copper interconnects and 300mm wafer sizes was considered to be the most difficult transition in its long and incredibly efficient history. The next chapter will be even tougher. It’s not that change is a foreign concept to semiconductor design and manufacturing. In fact, it’s probably the only constant over the past 50 years. But in the past, those changes tended ... » read more

High NA EUV Litho May Require Larger Photomask Size


By Jeff Chappell With extreme ultraviolet lithography (EUV) potentially being used in pilot production in a few years, it raises the question of larger photomasks sizes—will the industry need them, and if so, when? While there has been discussion of late about the possible need to transition to a larger mask size, veterans of the mask business may feel it's déjà vu all over again. Back... » read more

450mm: Out Of Sync


By Mark LaPedus The IC industry has been talking about it for ages, but vendors are finally coming to terms with a monumental shift in the business. The vast changes involve a pending and critical juncture, where the 450mm wafer size transition, new device architectures and other technologies will likely converge at or near the same time. In one possible scenario, 450mm fabs are projected ... » read more

The Week In Review: July 15


By Mark LaPedus There are more problems surfacing with extreme ultraviolet (EUV) lithography. Yes, the light source remains a problem, but the resists appear to be in decent shape. “The next challenge is the mask blank,” said Stefan Wurm, director of Sematech’s lithography program. The new problem involves ion beam deposition, which apparently is causing defects and overfill on EUV masks... » read more
