Abstract
A semiconductor structure is provided. The semiconductor structure includes a semiconductor substrate, a dielectric layer, a dielectric structure and an electrode structure. The dielectric layer is on an upper substrate surface of the semiconductor substrate. The dielectric structure and the semiconductor substrate have opposing first and second interfaces therebetween. The electrode structure comprises an electrode truck portion and at least one electrode branch portion. The at least one electrode branch portion is extended from the electrode truck portion down into the dielectric structure. The at least one electrode branch portion and the first interface have the smallest gap distance substantially bigger than 300 Å therebetween.
