Display device

Within one pixel element 200, two display circuits corresponding to the analog display mode and the digital display mode are disposed such that they are adjacent to each other. One of these two display circuits can be selected through the circuit selection circuits 40 or 43. Since the high voltage power line 150 of the retaining circuit 110, which is used under the digital display mode, also performs as the signal selection line 88, it is possible to have the high density integration of the pixel element 200. Also, the bias voltage Vsc supplied through the selection storage capacitor line 81 is same as the signal A. Therefore, the storage capacitor line 81 is connected to the drain of the TFT 122 of the signal selection circuit 120 so that the signal line 82 for supplying the signal A can be omitted. Thus, the high-density integration of the pixel element 200 can be achieved.

Reverse mask and nitride layer deposition for reduction of vertical capacitance variation in multi-layer metallization systems

Excessive variation in vertical (i.e., inter-level) capacitance of multi-level metallization semiconductor devices resulting in poor RC time constants of finished devices, and over-etching of borderless vias leading to inter-level short-circuits, are simultaneously eliminated or substantially reduced by selectively providing an etch-resistant masking material at thinner, i.e., recessed, portions of a first, low k gap fill material blanket-deposited over spaced-apart features of a metallization pattern and in the spaces therebetween. The surfaces of thicker, non-recessed portions thereof are etched so as to be substantially co-planar with the feature surfaces and the recessed portions. The etch-resistant mask is then removed, and second and third dielectric layers deposited over the planarized surface. The second and third dielectric layers are selected such that the second dielectric layer etches at a substantially slower rate than the third dielectric layer, thereby serving as a partial etch stop layer preventing deleterious over-etching of the borderless via.
