A standardized way to verify integrated circuit designs. The Journal of Micro/Nanopatterning, Materials, and Metrology (JM3) publishes peer-reviewed papers on the core enabling technologies that address the patterning needs of the electronics industry. With the myriad features addressing an ever-expanding array of requirements, today’s power system designer, similar to the conductor of an orchestra, must ensure that each cutting-edge sub-system and feature work together in unison so the performance of the whole exceeds the sum of its parts. As the semiconductor industry strives to catch back up to Moore’s Law cadence, 3D memory will continue adding layers, atomic scale FinFETS will continue to shrink, GAAFET (Gate-All-Around FET) will become a reality, and RF process power will continue to be an ever more critical enabler, “drawing-in” even more of the critical feature patterns.

We will describe dynamics and process implications that are raising the importance of RF process power to the extent it is seen as fundamentally enabling in today’s semiconductor wafer device patterning. Transitions between steps in modern process recipes may involve major changes to power level, gas flows and pressure, and consequently produce sharp changes to the plasma impedance. These lamps produce light across a broad spectrum with several strong peaks in the ultraviolet range. EUV lithography with high numerical aperture optics typically requires very thin layers of photoresists, which are difficult to achieve uniformly. Despite the technical progression, for much of its use in semiconductor manufacturing, RF generators and matching networks were largely seen as “dumb black boxes.” The RF generator power level was selected and expected to simply provide constant output power at that power level. The increase in sophistication is along the lines of the progression from landline phones to analog cell phones to digital network phones to today’s smartphones. A memory architecture in which memory cells are designed vertically instead of using a traditional floating gate. In this basic case, the engine and the transmission can be unaware of each other and act as black boxes to one another.

To form the tall memory stacks in 3D devices or the intricate 3D shapes in logic gate formation, etch and deposition processes increasingly require complex multi-step recipes.
