Memory device with capacitor and diode

摘要

One embodiment of the present invention relates to an integrated circuit that includes a memory cell. The memory cell includes a capacitor configured to store a charge or voltage. The capacitor includes a first semiconductor fin having a first conductivity type and overlying a semiconductor body, a dielectric overlying at least part of the semiconductor fin, and a gate electrode overlying the dielectric. The memory cell also includes a diode. The diode includes an end portion of the first semiconductor fin and a second semiconductor fin that forms a junction with the end portion of the first semiconductor fin. The second semiconductor fin has a second conductivity type and includes first and second legs in different directions from the junction. Other devices and methods are also disclosed.
