Ivy Bridge Settles Old Bet


Think back seven years to 2005. Those were boom times with the housing market rising, the dollar high, 65nm node chips on the horizon and EUV the great future lithography hope. EUVL was late for the next (45nm) node, but a great new idea had appeared to fill the gap—water immersion scanning with 193nm exposure! But how far could wet 193nm lithography go before EUVL or some new thing, such as ... » read more

Revisiting Moore’s Law


Moore’s Law was predicted to end at 1 micron. It was predicted to die off twice by Gordon Moore himself. And it has vacillated between 18 and 24 months on at least a couple of occasions since it was first introduced in 1965. From a technology perspective, there is no reason to assume it will ever die. It has gone from microns to nanometers and it can continue well into the picometer range.... » read more

Why 450mm wafers?


Why is 450-mm development so important to Intel (and Samsung and TSMC)? A few years ago, Intel and TSMC began heavily promoting the need for a transition from the current standard silicon wafer size, 300 mm, to the new 450-mm wafers.  While many have worked on 450-mm standards and technology for years, it is only recently that the larger wafer has received enough attention and support (not ... » read more

DSA Moves To R&D Pilot Lines


By Mark LaPedus Directed self-assembly (DSA), an alternative lithography technology that makes use of block copolymers, is still in the R&D stage for semiconductor production. But as the exotic patterning technology continues to make astounding progress, there are signs the IC industry is accelerating its efforts to bring DSA from the lab to the fab. In fact, DSA suddenly has become a ... » read more

Aloha Lithography!


An excuse to travel to Hawaii?  You don’t have to ask me twice.  Especially if it is the Big Island, my favorite of the Hawaiian isles.  My excuse this time?  The 3-beams conference, also called triple-beams, EIPBN, or occasionally (rarely) the International Conference on Electron, Ion and Photon Beam Technology & Nanofabrication. The conference was held last week (May 29 – June ... » read more

You Nits – a different way to think about nano-lithography


Once in a while, it is fun to go and listen to what the IC guys are up too…its jaw dropping stuff. The trouble with reeling off the capability in industry standard units is that it is impossible to put in any perspective. Units are important, or as my physics teacher used to say when we made a mistake “You nits”. Translation…in England a nitwit is a stupid person ! The 22 nm node ... » read more

If Computers Could Write


I have many titles.  Gentleman scientist.  Consultant.  Husband.  Dad.  Some are self-applied (the advantage of being my own boss), and some are earned.  One that I am proud of, and take seriously, is the title of “writer”.  Writing well is not easy, and I have the somewhat old-fashioned idea that I should only write if I have something worthwhile to say.  So when I do write somethi... » read more

EUV glass still less than half full, but level is rising


EUV first drew the semiconductor industry’s attention in the late 1990s, as lithographers began to consider the “post-optical” future. At that time, the future was expected to arrive with the 100-nm technology node, by 2004. ArF lithography turned out to be far more extensible than anticipated, though, and is still going strong fifteen years later. Which is fortunate given that, as we now... » read more

Lithography: How Slow Can We Go?


Moore’s Law has always been about economics:  if we follow the trend of Moore’s Law, we can reduce the cost per function for our integrated circuits, making chips more powerful for the same cost, or making chips of a given capability cheaper.  Historically, cost per function has decreased by about 29% per year, corresponding to a factor of 2 decrease in cost every two years.  There are s... » read more
