State-of-the-art chips will always include some portions which are memory arrays, which also happen to be the densest portions of the chip. Arrayed features are the main targets for lithography evaluation, as the feature pitch is well-defined, and is directly linked to the cost scaling (more features per wafer) from generation… Read More
Plasma Etching, ALE, and RIE (SEMI University)
This course discusses the fundamentals of plasma assisted phenomena and reactive ion etching (RIE) processes. The emphasis is on the physical and chemical processes that determine the consequences of a reactive gas plasma/surface interaction. The role of energetic ions as encountered in RIE systems is discussed in detail … Read More
