4-inch GaN Substrates
4-inch GaN Substrates refers to semiconductor materials or substrates within the named composition/process category.

Product & engineering
Understand the product.
Composition, crystal or epitaxial structure, stock dimensions, surface and qualification define inputs; generation/diameter labels do not establish electrical performance.
What turns activity into demand
Purchases need an identified composition or grade, supplied form and accepted specification. Material quantities and purchases of finished equipment are different demand measures; a category label does not establish qualified supply.
The commercial boundary
Use the selected edition’s product level, geography, years and measurement basis. Materials, components, finished systems and services are separate commercial boundaries unless the edition explicitly combines them.
Which composition, supplied form and specification define 4-inch GaN Substrates?
Composition, crystal or epitaxial structure, stock dimensions, surface and qualification define inputs; generation/diameter labels do not establish electrical performance.
