New Patterning Paradigm?

Chip scaling is becoming more difficult at each process node, but the industry continues to find new and innovative ways to solve the problems at every turn. And so chipmakers continue to march down the various process nodes. But the question is for how much longer? In fact, at 16nm/14nm and beyond, chipmakers are finding new and different challenges, which, in turn, could slow IC scaling or br... » read more

What Happened To Next-Gen Lithography?

Chipmakers continue to march down the process technology curve. Using today’s optical lithography and multiple patterning, the semiconductor industry is scaling its leading-edge devices far beyond what was once considered possible. The question is how far can the industry extend 193nm immersion [getkc id="80" comment="lithography"] and multiple patterning before these technologies become t... » read more

Multi-beam Sees The Light

The multiple-beam electron-beam market is going in two separate directions at once. Multi-beam for photomask writing is set to take off. The other market--multi-beam for direct-write lithography applications—is still in the early stages and remains in flux. In the multi-beam direct-write segment, for example, multiple sources indicate that KLA-Tencor is exiting this market to focus on its ... » read more

DSA, Multi-beam Make Steady Progress

Semiconductor Engineering sat down to discuss current and future lithography challenges with Laurent Pain, lithography lab manager at CEA-Leti. What follows are excerpts of that conversation. SE: CEA-Leti has two major programs in lithography. One is in directed self-assembly (DSA) and the other is in multi-beam e-beam. Let’s start with multi-beam. What is Leti doing in multi-beam and what... » 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
