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 > within a single semiconductor body or layer in a solid phase; between different semiconductor bodies or layers, both in a solid phase

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 > within a single semiconductor body or layer in a solid phase; between different semiconductor bodies or layers, both in a solid phase
