EUV Light Source Makes Progress


EUV Lithography light source maker, Gigaphoton has developed a laser-produced plasma (LPP) light source prototype model that can produce a maximum of 92 watts. This is more than double the 43 watts produced using a traditional LPP light source. Figure 1 conceptual diagram of EUV exposure.

Billions And Billions Invested


Over the years, next-generation [getkc id="80" kc_name="lithography"] (NGL) has suffered various setbacks and delays. But until recently, the industry basically shrugged its shoulders and expressed relatively little anxiety about the NGL delays. After all, optical lithography was doing the job in the fab and NGL would eventually materialize. Today, however, the mood is different. In fact, th... » read more

EUV Reaches A Crossroads


[gettech id="31045" comment="EUV"] (EUV) [getkc id="80" comment="lithography"] is at a crossroads. 2014 represents a critical year for the technology. In fact, it may answer a pressing question about EUV: Does it work or not? It’s too early to make that determination right now, but there are more uncertainties than ever for the oft-delayed technology. Originally aimed for the 65nm node in... » read more

Week In Review: Manufacturing, Design, Test


Reports have surfaced that IBM’s semiconductor unit is on the block, and there has been discussion about the reasons and the aftermath. Sources say there are at least two potential buyers for the unit—Samsung and TowerJazz. Apparently, the talks between IBM-Samsung and IBM-TowerJazz have been going on for some time. Multiple sources believe that Samsung is interested in buying IBM’s advan... » 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

Reaching For The Reset Button In Lithography


By Mark LaPedus Amid ongoing delays and setbacks, extreme ultraviolet (EUV) lithography and multi-beam e-beam have both missed the 10nm logic node. So for the present, chipmakers must take the brute force route at 10nm by using 193nm immersion with multiple patterning. Now, it’s time to hit the reset button. For the 7nm node, chipmakers currently are lining up the lithographic competition... » read more

Laser pulses illuminate downturn and recovery


[caption id="attachment_7313" align="alignnone" width="728"] Laser pulses per month for Gigaphoton's KrF and ArF lasers[/caption] I thought this image was a nice illustration of exactly what happened in the most recent industry downturn. The graphic shows the number of pulses per laser, per month, for Gigaphoton's installed base of ArF and KrF lasers. A stepper processing 1,000 wafers per mo... » read more
