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

Evaluate MEMS Devices out-of-fab Before Fabrication
MEMS design and fabrication is highly complex in the sense that the fabrication process heavily depends on the design, unlike IC fabrication which has a standard set of processes. A slight change in MEMS design can alter its fabrication steps to a large extent. For example, setting device parameters such as capacitance or linear… Read More
