Dual three-dimensional (3D) resistor and methods of forming
Various embodiments include dual three-dimensional (3D) resistor structures and methods of forming such structures. In some embodiments, a dual 3D resistor structure includes: a dielectric layer having a first set of trenches extending in a first direction through the dielectric layer; and a second set of trenches overlayed on the first set of trenches, the second set of trenches extending in a second direction through the dielectric layer, the second set of trenches and the first set of trenches forming at least one dual 3D trench; and a resistor material overlying the dielectric layer and at least partially filling the at least one dual 3D trench along the first direction and the second direction.
