This is an abbreviated educational map, not a single standard path for actual fabrication. Sequences, repetitions, and materials differ between memory and logic, products, and process generations. Oxidation, ion implantation, heat treatment, planarization, interconnect formation, and other operations are not all shown as separate nodes. Companies illustrate roles based on public products and technologies; they are not lists of exclusive suppliers or verified counterparties. Economic significance and watch points are principle-based educational interpretations, not forecasts of earnings or share prices or investment recommendations.
Educational diagram. Actual factory layouts and equipment proportions differ, and many processes repeat.

Process explanation
Deposition forms thin films of conductors, insulators, and other materials at the required locations and thicknesses. Methods such as ALD are selected to suit materials and shapes. Rather than stopping after a single layer, deposition combines with patterning and removal to create multiple layers.
Industry perspective
Why it matters
Examining film quality and processing speed—not merely process counts—shows why material and equipment choices affect productivity.
Indicators to watch
Is film thickness uniform even in complex structures?
Can new materials be used with existing processes?
