Introducing the Surfscan SP3 450


The Surfscan® SP3 450 is the first of KLA-Tencor’s process control systems capable of handling and inspecting 450mm wafers. As a new configuration of the market-leading Surfscan SP3 platform, these fully-automated unpatterned wafer inspection systems feature unique deep ultra-violet (DUV) sensitivity and unique high-resolution SURFmonitorTM surface quality characterization to support sub-20nm node requirements. The Surfscan SP3 450 enables manufacturing process control for 450mm polished silicon and epitaxial silicon substrates and also delivers critical capability for manufacturers of 450mm process equipment, such as wet clean tools, CMP pads, slurries and polishers, film deposition tools and annealing systems.
13th Annual Lithography Users’ Forum


Lithography Challenges for (Sub 20nm) Semiconductor Technology Nodes

This LUF keynote presentation explores various technologies for scaling IC devices to follow Moore’s law. Several advanced patterning and layout optimization techniques for continued geometrical scaling in 193i lithography are discussed, including self aligned double patterning (SADP), directed self assembly and the move toward local interconnect layouts in advanced logic and SRAM devices. In addition, a comprehensive overview on the status of EUV lithography is presented, including an update on EUV resists, line width roughness and EUV masks. EUV lithography benefits are also examined, including its intrinsically higher resolution for printing patterns such as holes, trenches and high resolution cuts.
