    摘要: A method of manufacturing a semiconductor device using shallow trench isolation is provided, wherein a plurality of protrusions are formed in the exposed surface of the mask layer overlying the active area of the device. The protrusions are preferably formed by forming a photo-resist layer on the surface of the mask layer and patterning the photo-resist layer such that the photo-resist layer defines a plurality of protrusion areas and a depression area within the defined active area. A portion of the mask layer is removed in the defined depression area to form a plurality of protrusions in the mask layer. Thereafter, a dielectric layer is deposited on the exposed surface of the mask layer and in the shallow trench and evenly planarized.

    摘要: A halo implant (42, 44) for an MOS transistor (10) is formed in a semiconductor substrate (12) at a shallow implant angle, relative to normal to the substrate surface (29). A polysilicon gate structure (32, 33) is formed over a gate oxide (28) and then a hard mask (70), such as a TEOS-generated layer of silicon oxide, is deposited on an upper surface (68) of the gate. The mask is etched with a blanket anisotropic etch to form a cap-shaped mask (72). The shape of the cap causes the dopant for the halo implant to penetrate to a depth which follows the contour of the cap. Thus, halo implants may be formed which extend under the gate structure without the need for large angle implants and resultant shadowing problems caused by adjacent devices.

    摘要: A method for manufacturing a semiconductor wafer uses a reticle having a plurality of spaced apart circuit images of identical patterns or images of a common level of a single integrated circuit formed on the reticle and arranged in columns and rows about its central point. At least one column of spaced apart test images are formed outside of and adjacent an outermost column of circuit images. Radiation is projected through the reticle for exposing the patterns on the reticle onto an underlying wafer. A reticle holder having a pair of shutter elements aligned parallel to the columns of images selectively blocks the projection of radiation through the columns of the test images but are exposed in order to form test circuits on the wafer at selected locations.

    摘要: A contactless, self-aligned local interconnect structure provides a continuous silicide film electrically coupling an upper silicon structure to a lower silicon structure. The upper silicon structure overlaps the lower silicon structure and is insulated from the lower silicon structure by an insulating layer formed between the structures. The continuous silicide film electrically couples the two structures by bridging the gap formed by the insulating layer in the overlap region. The associated process for forming the local interconnect structure includes forming a lateral edge of the upper silicon structure extending over the lower silicon structure, forming a blanket metal film, then heating the metal film such that the metal film reacts with the exposed silicon of the upper silicon structure and the lower silicon structure to form a continuous silicide film which bridges the gap formed by the insulating layer which is formed of a thickness chosen to be suitably low. After the silicide film is formed, unreacted portions of the metal film are removed.

Each memory cell includes a pillar comprising a lower source/drain region for a cell access transistor electrically connected to the connection line, an upper source/drain region for the cell access transistor, and at least one channel region extending vertically between the lower and upper source/drain regions. Each memory cell further includes at least one lower dielectric layer vertically adjacent the substrate and laterally adjacent the pillar and at least one upper dielectric layer vertically spaced above the at least one lower dielectric layer and laterally adjacent the pillar. Further, each memory cell includes at least one gate for the at least one channel of the cell access transistor between the lower and upper dielectric layers so that the vertical spacing therebetween defines a gate length for the cell access transistor. A storage capacitor is also included in each memory cell adjacent the upper source/drain region of the cell access transistor and is electrically connected thereto.
