New integration and patterning schemes used in 3D memory and logic devices have created manufacturing and yield challenges. Industrial focus has shifted from the scaling of predictable unit processes ...

In this article, as in industry, advanced process control (APC) refers primarily to multi-variable control. Multivariable control means adjusting multiple single-loop controllers in unison, to meet ...

Comprehensive process optimization begins with an evaluation to identify the best combination of tooling, fixturing, machines, and cycle times. The Seco Engineered Solutions team evaluates the scope ...

To ensure success in semiconductor technology development, process engineers must set the allowed ranges for wafer process parameters. Variability must be controlled, so that final fabricated devices ...
