    Abstract: Dishing is known to be a problem after CMP of dielectric layers in which the distribution of embedded metal is non-uniform. This problem has been solved by populating those areas where the density of embedded metal is low with unconnected regions that, instead of being uniformly filled with metal, are made up of metallic patterns whose combined area within a given region is about half the total area of the region itself. Two examples of such patterns are a line stripe pattern (similar to a parquet flooring tile) and a checker board pattern. Data is presented comparing the parasitic capacitances resulting from the use of patterns of this type relative to conventional solid patterns. The effect of aligning the regions so as to reduce their degree of overlap with wiring channels is also discussed.

    Abstract: An improved dual damascene structure, and process for manufacturing it, are described in which the via hole is first lined with a layer of silicon nitride prior to adding the diffusion barrier and copper. This allows use of a barrier layer that is thinner than normal (since the silicon nitride liner is an effective diffusion barrier) so that more copper may be included in the via hole, resulting in an improved conductance of the via. A key feature of the process that is used to make the structure is the careful control of the etching process. In particular, the relative selectivity of the etch between silicon oxide and silicon nitride must be carefully adjusted.

    Abstract: The present invention discloses a hybrid polysilicon/amorphous silicon TFT device for switching a LCD and a method for fabrication wherein a n.sup.+ doped amorphous silicon layer is advantageously used as a mask during a laser annealing process such that only a selected portion of a hydrogenated amorphous silicon layer is converted to a crystalline structure while other portions retain their amorphous structure. As a result, a polysilicon TFT and at least one amorphous silicon TFT are formed in the same structure and the benefits of both a polysilicon TFT and amorphous silicon TFT such as a high charge current and a low leakage current are retained in the hybrid structure.

    Abstract: A method of fabricating a polycrystalline silicon thin-film transistor having two symmetrical lateral resistors is disclosed. Two sub-gates are formed along with a gate in the gate metal or polysilicon layer of the thin-film transistor. The two sub-gates that are located symmetrically on the two sides of the gate have equal distances to the gate. One sub-gate is near the drain of the thin film transistor and the other near the source. Two sections in the polycrystalline silicon layer of the thin film transistor are blocked by the two sub-gates and no impurity material is doped. The two undoped sections form the symmetrical lateral resistors of this invention. The lateral resistor near the drain decreases the electric field in the nearby depletion area when the thin-film transistor is switched off. The current leakage is reduced.
