Abstract:
1. A system for electrostatic discharge protection, the system comprising: a first transistor coupled to a first system and including a first gate, a first dielectric layer located between the first gate and a first substrate, a first source, and a first drain, the first system including or coupled to a core transistor, the core transistor including a second gate, a second dielectric layer located between the second gate and a second substrate, a second source, and a second drain; wherein: the first transistor is selected from a plurality of transistors, the plurality of transistors including a plurality of gate regions, a plurality of source regions, and a plurality of drain regions; each of the plurality of gate regions intersects a polysilicon region, the polysilicon region being separated from the first substrate by a third dielectric layer, at least a part of the polysilicon region located on an active area; the polysilicon region is adjacent to a first doped region and a second doped region, the first doped region and the second doped region being associated with opposite charge polarities; the second dielectric layer and the third dielectric layer are associated with the same composition and the same thickness; the second gate and the polysilicon region are associated with the same composition and the same thickness.
