Combinations of enhancement-mode IGFETs and depletion-mode IGFETs

Introduced: January 2025

Full Title

Full titles differ between systems:

IPC:

Integrated devices formed in or on semiconductor substrates that comprise only semiconducting layers, e.g. on Si wafers or on GaAs-on-Si wafers > characterised by the integration of at least one component covered by groups or , e.g. integration of IGFETs > of only field-effect components > of only insulated-gate FETs [IGFET] > Combinations of enhancement-mode IGFETs and depletion-mode IGFETs

CPC:

Integrated devices formed in or on semiconductor substrates that comprise only semiconducting layers, e.g. on Si wafers or on GaAs-on-Si wafers > characterised by the integration of at least one component covered by groups H10D12/00 or H10D30/00, e.g. integration of IGFETs (H10D84/40 takes precedence) > of only field-effect components > of only insulated-gate FETs [IGFET] > Combinations of enhancement-mode IGFETs and depletion-mode IGFETs

No child classifications to compare. This is a leaf node in both IPC and CPC.
