Diffusion of dopants within, into or out of semiconductor bodies or layers

Introduced: January 2026

Full Title

Full titles differ between systems:

IPC:

Diffusion of dopants within, into, or out of wafers, substrates or parts of devices > Diffusion of dopants within, into or out of semiconductor bodies or layers

CPC:

Diffusion of dopants within, into or out of wafers, substrates or parts of devices (during formation of materials H10P14/00) > Diffusion of dopants within, into or out of semiconductor bodies or layers

CPC subdivides this area 3x more granularly than IPC with 5 additional codes.

5 codes are CPC-only extensions.

IPC defines codes here since 2026.
