DEFINITION

Classification: 257/528

Passive components in ICs:

(under subclass 499) Subject matter wherein the device is contained in a single, monolithic chip with electrical components which are passive, i.e., which do not have gain, for example, pure capacitors, inductors, or resistors.

379, for a passive component combined with an IGFET device in an integrated circuit.

516, for passive components in an integrated circuit with dielectric in groove and pn junction isolation.

904, for a FET combined with passive components adapted for use as a static memory cell.
