Abstract
A semiconductor structure may include a heater surrounded by a second dielectric layer, a projection liner on top of the second dielectric layer, and a phase change material layer above the projection liner. A top surface of the projection liner may be substantially flush with a top surface of the heater. The projection liner may separate the phase change material layer from the second dielectric layer. The projection liner may provide a parallel conduction path in the crystalline phase and the amorphous phase of the phase change material layer. The semiconductor structure may include a bottom electrode below and in electrical contact with the heater and a top electrode above and in electrical contact with the phase change material layer.
