3D Effects At 20nm And Beyond


At the 20nm process node and below, attenuated phase shift masks (PSM) are used in the photolithography process, which results in approximately 70nm of topography. This now must be accounted for using 3D mask approximation. Aki Fujimura, CEO of [getentity id="22864" comment="D2S"], explained that in terms of [getkc id="80" comment="lithography"], where simulation-based technologies are used,... » read more

Challenges Mount For Patterning And Masks


Semiconductor Engineering sat down to discuss lithography and photomask trends with Uday Mitra, vice president and chief technology officer for the Etch Business Unit at [getentity id="22817" e_name="Applied Materials"]; Pawitter Mangat, senior manager and deputy director for EUV lithography at [getentity id="22819" comment="GlobalFoundries"]; Aki Fujimura, chief executive at [getentity id="228... » read more

Issues And Options At 5nm


While the foundries are ramping up their processes for the 16nm/14nm node, vendors are also busy developing technologies for 10nm and beyond. In fact, chipmakers are finalizing their 10nm process offerings, but they are still weighing the technology options for 7nm. And if that isn’t enough, IC makers are beginning to look at the options at 5nm and beyond. Today, chipmakers can see a p... » read more

More Lithography Options?


Lithographers face some tough decisions at 10nm and beyond. At these nodes, IC makers are still weighing the various patterning options. And to make it even more difficult, lithographers could soon have some new, and potentially disruptive, options on the table. On one front, the traditional next-generation lithography (NGL) technologies are finally making some noticeable progress. For examp... » read more

The Week In Review: Manufacturing


At the SPIE Advanced Lithography conference in San Jose, Calif., there were several takeaways. First, the battle for lithography share is heating up at Intel. “We believe Nikon still holds a decent position at Intel, but with ASML gaining some share at 10nm. Nikon could regain some share with its new platform at 7nm, in our view, but it is early to tell. We believe Nikon has improved its posi... » read more

The Week In Review: Manufacturing


For years, chipmakers have attempted to build fabs in India. So far, however, India has failed to set up modern fabs and for good reason. There are issues in terms of obtaining dependable power and water for a fab in India, according to Will Strauss, president of Forward Concepts, who added that India also suffers from government bureaucracy. India is still trying. Last week, Cricket Semicon... » read more

5 Disruptive Mask Technologies


Photomask complexity and costs are increasing at each node, thereby creating a number of challenges on several fronts. On one front, for example, traditional single-beam e-beam tools are struggling to keep up with mask complexity. As a result, the write times and costs continue to rise. Mask complexity also impacts the other parts of the tool flow, such as inspection, metrology and repair. I... » read more

How To Extend Litho Scaling


IC mask [getkc id="80" comment="lithography"] today is sophisticated and complex. It's also a work in progress with a lot of unknowns as the industry struggles to increase productivity while reducing risk. The bulk of the work currently is focused on trying to figure out what would be a practical scheme for patterning lithography that could be used at 10nm and 7nm, said Gandharv Bhatara, Ca... » read more

Tech Talk: Photomask Challenges


GlobalFoundries' Bob Pack talks with Semiconductor Engineering about new problems experienced by photomask shops and how does lithography affects it all. [youtube vid=8hJwVhaZhFc] » read more
