    摘要: A memory includes a phase-change memory cell and a circuit. The phase-change memory cell can be set to at least three different states including a substantially crystalline state, a substantially amorphous state, and at least one partially crystalline and partially amorphous state. The circuit applies a first voltage across the memory cell to determine whether the memory cell is set at the substantially crystalline state and applies a second voltage across the memory cell to determine whether the memory cell is set at a partially crystalline and partially amorphous state.

    摘要: A selectively silicided semiconductor structure and a method for fabricating same is disclosed herein. The semiconductor structure has suicide present on the polysilicon line between the N+ diffusion or N+ active area and the P+ diffusion or active area at the N+/P+ junction of the polysilicon line, and silicide is not present on the N+ active area and the P+ active area. The presence of this selective silicidation creates a beneficial low-resistance connection between the N+ region of the polysilicon line and the P+ region of the polysilicon line. The absence of silicidation on the N+ and P+ active areas, specifically on the PFET and NFET structures, prevents current leakage associated with the silicidation of devices.

    摘要: A method of forming retrograde n-wells and p-wells. A first mask is formed on the substrate and the n-well implants are carried out. Then the mask is thinned, and a deep p implant is carried out with the thinned n-well mask in place. This prevents Vt shifts in FETs formed in the n-well adjacent the nwell-pwell interface. The thinned mask is then removed, a p-well mask is put in place, and the remainder of the p-well implants are carried out.

    摘要: Vertical field effect transistor semiconductor structures and methods for fabrication of the vertical field effect transistor semiconductor structures provide an array of semiconductor pillars. Each vertical portion of each semiconductor pillar in the array of semiconductor pillars has a linewidth greater than a separation distance to an adjacent semiconductor pillar. Alternatively, the array may comprise semiconductor pillars with different linewidths, optionally within the context of the foregoing linewidth and separation distance limitations. A method for fabricating the array of semiconductor pillars uses a minimally photolithographically dimensioned pillar mask layer that is annularly augmented with at least one spacer layer prior to being used as an etch mask.

    摘要: A process for manufacturing a PCM device comprises forming a dielectric, producing a via in the dielectric starting at an area on the surface of the dielectric by forming a via opening in the area and extending the opening into the dielectric toward and then terminating at an electrode comprising a first electrode in the dielectric. We form a spacer layer contiguous with the side walls of the via and fill the via with a PCM. We then remove the surface of the dielectric to leave a PCM cusp at the opening of the via, cap the PCM cusp with a low density capping film; densify the PCM and capping film to obtain a high density capping film that exerts compressive pressure on the high density PCM in a direction toward the first electrode to enhance electrical contact between the PCM and the first electrode.
