Gate Runner Contact Layout for Uniform Gate Signal Timing

The patent extracts the gate contact region from the gate runner structure, forming a separate integrated contact structure. This allows the gate runner to be shortened and repositioned such that its end overlaps with the gate frame above the active region, while the gate contact region provides the actual electrical connection. This separation resolves the contradiction by eliminating the need for extensive gate runner coverage while maintaining reliable, timely signal transmission to all unit cells.

The gate contact region acts as an intermediary between the gate runner and the gate frame/unit cells. Instead of the gate runner directly covering and connecting to all areas of the gate frame, the gate contact region serves as the intermediate connection point. This mediator structure enables compact gate runner placement while ensuring uniform signal distribution timing across all unit cells through optimized electrical connection geometry.

The patent applies local quality by concentrating the gate contact region specifically above the active region rather than distributing it uniformly across the entire gate frame. The gate runner is positioned to overlap with the gate frame only in the regions corresponding to active unit cells, where signal transmission is needed. This localized approach maintains signal uniformity for functional areas while reducing overall structural complexity.

The gate runner is designed to extend partially along the gate frame rather than covering the entire perimeter. The runner's end overlaps with the gate frame above the active region, providing sufficient contact for all unit cells without excessive extension. This partial action achieves the necessary signal distribution uniformity while avoiding the complexity of complete gate frame coverage.
