Semiconductor devices including 3-D structures with support pad structures and related methods and systems

摘要

A semiconductor device may include a semiconductor substrate and a plurality of three-dimensional capacitors on the semiconductor substrate. Each of the plurality of three-dimensional capacitors may include a first three-dimensional electrode, a capacitor dielectric layer, and a second three-dimensional electrode with the first three-dimensional electrode between the capacitor dielectric layer and the semiconductor substrate and with the capacitor dielectric layer between the first and second three-dimensional electrodes. A plurality of capacitor support pads may be provided with each capacitor support pad being arranged between adjacent first three-dimensional electrodes of adjacent three-dimensional capacitors with portions of the capacitor dielectric layers between the capacitor support pads and the semiconductor substrate. Related methods and apparatuses are also discussed.
