Abstract:
In a liquid crystal display (LCD) structure, a plurality thin film transistors (TFTs) and operative interconnections formed on a substrate, comprising:a plurality of active areas of polycrystalline silicon formed on the substrate, each active area including source, drain, and channel regions of a TFT;a gate electrode on said channel region of each said active area, and source and drain electrodes on the respective source and drain regions of each active area; anda plurality of conductive lines formed on the substrate to provide operative interconnections to selected TFTs on the substrate, each of said conductive lines being at least 2 microns wide, said conductive lines including a plurality of first conductive lines operatively connected to the gate electrodes and a plurality of second conductive lines operatively connected to a second electrode of each selected TFT, the second electrode being the source or drain electrode; andsaid first and second conductive lines on the substrate, and the respective gate and second electrodes to which the lines are operatively connected on each TFT, having first/second/third layers as follows: TiN/Cu/TiN.
