Abstract:
1. A semiconductor device comprising: a substrate having dopant material of a first conductivity type; a plurality of trenches disposed within the substrate; a diffusion region disposed proximate to the plurality of trenches, the diffusion region having dopant material of a second conductivity type; an isolation region disposed adjacent to the diffusion region; and a metal-insulator-metal (MIM) capacitor formed within each trench of the plurality of trenches, wherein the plurality of trenches have an aspect ratio ranging from about one hundred and twenty-five to one (125:1) to about one hundred and fifty to one (150:1) such that the metal-insulator-metal capacitor comprises a capacitive density ranging from three hundred femtoFarads per square micrometer (300 fF/um
