Material structures, e.g. crystalline structures, film structures or crystal plane orientations

Introduced: January 2025

Full Title

Full titles differ between systems:

IPC:

Constructional details of devices covered by this subclass > Semiconductor bodies > Material structures, e.g. crystalline structures, film structures or crystal plane orientations

CPC:

Constructional details of devices covered by this subclass (constructional details of integrated devices, or assemblies of multiple devices, comprising at least one element in which radiation controls the flow of current H10F39/00) > Semiconductor bodies > Material structures, e.g. crystalline structures, film structures or crystal plane orientations

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2025.
