Lithography for Nano-Technology CMOS ICs
This one-day course describes the state-of-the-art and latest advances in lithography for today’s most advanced CMOS nanotechnology ICs.
Course Description:
This course provides a broad, deep treatment of lithography, the key driver technology in CMOS IC fabrication. It covers all critical lithographic technology elements, from basic concepts to leading-edge technology and applications issues for today’s most advanced CMOS nanotechnology ICs. It will describe the variations in lithographic technology and circuit layout design techniques that are required to optimize performance and control variation in different IC applications for logic and memory. This course is appropriate for professional development of process engineers, applications engineers, device engineers, VLSI design engineers, technical marketing engineers and managers, and process equipment engineers and scientists who wish to improve their understanding of lithography for nanotechnology CMOS ICs. The material is presented using intuitive visual illustrations linked to relevant physics equations, supported by state-of-the-art 2D & 3D graphics and numerous SEM and TEM photographs of real-world, leading-edge CMOS lithographic structures. Key references are provided for independent follow-up studies.
The course begins with a crisp overview of all lithography technology elements and basic concepts. It then describes in detail all leading-edge advances and issues in photoresist masks, resolution enhancement techniques (RET), and exposure tools (steppers, scanners). It has in-depth treatment of the latest advances in double patterning technologies, computational lithography, and design for manufacturability (DFM) techniques. The latest techniques to optimize IC performance and control manufacturing variation for different IC applications (HP logic, SRAM, DRAM & Flash) are explained.
