H10F 77/164

Polycrystalline semiconductors

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 > Non-monocrystalline materials, e.g. semiconductor particles embedded in insulating materials > Polycrystalline semiconductors

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 > Non-monocrystalline materials, e.g. semiconductor particles embedded in insulating materials (H10F77/169 takes precedence) > Polycrystalline semiconductors

Of 1 combined children, 0 exist in both systems.

1 codes are CPC-only extensions.
