Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as test instruments rather than semiconductor material
Functional test wafers with embedded sensors may fall under analytical instruments.
If for epitaxial wafers without transistor patterning
Coatings on semiconductor base are chemical preparations before device fabrication.
