Big Changes In Patterning


Aki Fujimura, CEO of [getentity id="22864" comment="D2S"], sat down with Semiconductor Engineering to discuss patterning issues at 10nm and below, including mask alignment, the need for GPU acceleration, EUV's future impact on the total number of masks, and what the re-introduction of curvilinear shapes will mean for design. SE: Patterning issues are getting a lot of attention at 10nm and 7n... » read more

Battling Fab Cycle Times


The shift from planar devices to finFETs enables chipmakers to scale their processes and devices from 16nm/14nm and beyond, but the industry faces several challenges at each node. Cost and technical issues are the obvious challenges. In addition, cycle time—a key but less publicized part of the chip-scaling equation—also is increasing at every turn, creating more angst for chipmakers and... » read more

Deploying Multi-Beam Mask Writers


Elmar Platzgummer, chief executive of IMS Nanofabrication, sat down with Semiconductor Engineering to discuss the company’s deal with Intel, photomasks, multi-beam mask writer technology and other topics. What follows are excerpts of that conversation. SE: This has been a significant year for IMS for two reasons. First, Intel recently announced plans to acquire IMS. Second, at the recent ... » read more

7nm Fab Challenges


Leading-edge foundry vendors have made the challenging transition from traditional planar processes into the finFET transistor era. The first [getkc id="185" kc_name="finFETs"] were based on the 22nm node, and now the industry is ramping up 16nm/14nm technologies. Going forward, the question is how far the finFET can be scaled. In fact, 10nm finFETs from Samsung are expected to ramp by ye... » read more

Multi-Beam Market Heats Up


The multi-beam e-beam mask writer business is heating up, as Intel and NuFlare have separately entered the emerging market. In one surprising move, [getentity id="22846" e_name="Intel"] is in the process of acquiring IMS Nanofabrication, a [gettech id="31058" t_name="multi-beam e-beam"] equipment vendor. And separately, e-beam giant NuFlare recently disclosed its new multi-beam mask writer t... » read more

Taming Mask Metrology


For years the IC industry has worried about a bevy of issues with the photomask. Mask costs are the top concern, but mask complexity, write times and defect inspection are the other key issues for both optical and EUV photomasks. Now, mask metrology, the science of measuring the key parameters on the mask, is becoming a new challenge. On this front, mask makers are concerned about the critic... » read more

Mask Metrology Challenges Grow


Photomasks are becoming more complex at each node. In fact, masks are moving from traditional shapes to non-orthogonal patterns and complex shapes, such as curvilinear mask patterns. To measure patterns and shapes on the mask, photomask makers use traditional critical-dimension scanning electron microscopes (CD-SEMs). In general, the CD-SEM, the workhorse metrology tool in the mask shop, use... » read more

Mask Supply Chain Preps For 10nm


As the semiconductor industry gears up for the 10nm logic node—now likely to begin in the second half of 2017—the photomask supply chain is preparing to grapple with the associated challenges, including dramatic increases in photomask complexity, write times and data volumes. The 10nm node will require more photomasks per mask set, the ability to print smaller and more complex features, ... » read more

Challenges Mount For Patterning And Masks


Semiconductor Engineering sat down to discuss [getkc id="80" comment="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 execu... » read more

Is Multi-Patterning Good for You?


I think we can all remember growing up and our parents making us take nasty-tasting medicines, or eat foods we didn’t like, or endure painful things like shots, all under the banner of “It is good for you!” We didn’t like it then, and we still don’t like it as adults. We would all prefer a way to lose weight while eating anything we want, or building strong muscles and aerobic health ... » read more
