    Abstract: A method for forming an interconnect wiring structure, such as a fuse structure, comprises forming an opening in an insulating layer using a phase shift mask (the opening having vertical sidewalls sloped sidewalls and horizontal surfaces), depositing a conductive material in the opening and removing the conductive material from the sloped sidewalls and horizontal surfaces, wherein the conductive material remains on the vertical sidewalls as fuse links.

    Abstract: A integrated circuit device and method for manufacturing an integrated circuit device includes forming a patterned gate stack, adjacent a storage device, to include a storage node diffusion region adjacent the storage device and a bitline contact diffusion region opposite the storage node diffusion region, implanting an impurity in the storage node diffusion region and the bitline contact diffusion region, forming an insulator layer over the patterned gate stack, removing a portion of the insulator layer from the bitline contact diffusion region to form sidewall spacers along a portion of the patterned gate stack adjacent the bitline contact diffusion region, implanting a halo implant into the bitline contact diffusion region, wherein the insulator layer is free from blocking the halo implant from the second diffusion region and annealing the integrated circuit device to drive the halo implant ahead of the impurity.

    Abstract: Methods of manufacturing trench-bounded buried-channel p-type metal oxide semiconductor field effect transistors (p-MOSFETs), as used in dynamic random access memory (DRAM) technologies, for significantly reducing the anomalous buried-channel p-MOSFET sensitivity to device width. In one embodiment, the method comprises the initiation of a low temperature annealing step using an inert gas after the deep phosphorous n-well implant step, and prior to the boron buried-channel implant and 850°C gate oxidation steps. Alternatively, the annealing step may be performed after the boron buried-channel implant and prior to the 850°C gate oxidation step. In another embodiment, a rapid thermal oxidation (RTO) step is substituted for the 850°C gate oxidation step, following the deep phosphorous n-well and boron buried-channel implant steps. Alternatively, an 850°C gate oxidation step may follow the RTO gate oxidation step.

    Abstract: A method for clearing an isolation collar (5) from a first interior surface of a deep trench at a location above a storage capacitor while leaving the isolation collar at other surfaces of the deep trench. A insulating material is deposited above a node conductor (3) of the storage capacitor. A layer of silicon (9) is deposited over the barrier material. Dopant ions are implanted at an angle (11) into the layer of deposited silicon within the deep trench, thereby leaving the deposited silicon unimplanted along one side of the deep trench. The unimplanted silicon is etched. The isolation collar is removed in locations previously covered by the unimplanted silicon, leaving the isolation collar in locations covered by the implanted silicon.
