Abstract:
1. A vertical semiconductor charge storage structure, comprising: a substrate, including a plurality of electrical contacts arranged in an array; a plurality of lower electrodes respectively corresponding to and electrically connecting to the plurality of contacts, each of the plurality of lower electrodes comprising a lower conductor electrically connected with the at least one electrical contact, a first side conductor disposed at one end of the lower conductor, and a second side conductor disposed at another end of the lower conductor; wherein the first side conductors and the second side conductors are interlaced and parallel to each other and form an included angle with the lower conductor; wherein the first side conductors are formed at a height greater than that of the second side conductors; a dielectric layer, formed on surfaces of the substrate and the plurality of lower electrodes; and an upper electrode, formed on a surface of the dielectric layer away from the substrate and the plurality of lower electrodes.
