    摘要： A method for transferring a pattern from a mask to a substrate (or wafer), comprises dividing a mask generation data file into a plurality of segments. The segments include a main pattern area and a stitching area. Each stitching area contains a respective common pattern. An image of an illuminated portion of the main pattern area is formed. Connection ends of the segments in a substrate area (or wafer area) are illuminated with an illumination beam. An image of the illuminated portion of the main pattern area is formed, and a halftone gray level dosage distribution is produced in the substrate area (or wafer area) corresponding to the common pattern. The common patterns of adjacent segments substantially overlap in the substrate area (or wafer area).

    摘要： A method of correcting, or compensating for errors encountered in the transfer of patterns is disclosed for use with high resolution e-beam lithography. In a first embodiment, optical proximity effects are incorporated into the e-beam proximity effects by superimposing the two effects to arrive at a compensated dosage level database to produce the desired patterns. In a second embodiment, etching effects are also superimposed on the previous driving database by compensating the e-beam proximity data twice, that is, by over correcting it, to further improve the transfer of patterns without the undesirable effects. It is shown that corrections for a number of other process steps can also be incorporated into the database that drives the e-beam lithography machine in order to achieve high resolution patterns of about one-quarter-micron technology.

    摘要： A method for fabricating a high-density array of crown capacitors with increased capacitance while reducing process damage to the bottom electrodes is achieved. The process is particularly useful for crown capacitors for future DRAM circuits with minimum feature sizes of 0.18 micrometer or less. A conformal conducting layer is deposited over trenches in an interlevel dielectric (ILD) layer, and is polished back to form capacitor bottom electrodes. A novel photoresist mask and etching are then used to pattern the ILD layer to provide a protective interlevel dielectric structure between capacitors. The protective structures prevent damage to the bottom electrodes during subsequent processing. The etching also exposes portions of the outer surface of bottom electrodes for increased capacitance (>50%). In a first embodiment the ILD structure is formed between pairs of adjacent bottom electrodes, and in a second embodiment the ILD structure is formed between four adjacent bottom electrodes.
