Methods of forming capacitors
Implementations of methods of forming capacitors may include depositing a first metal layer over a substrate, forming a photoresist layer over the first metal layer, patterning the photoresist layer, patterning the first metal layer using the pattern of the photoresist layer, depositing a dielectric layer over the first metal layer, and depositing a second metal layer over the dielectric layer to form a metal-insulator-metal capacitor.
1. A method of forming a capacitor comprising:
depositing a first metal layer over a substrate;
coupling a diblock copolymer over the first metal layer;
selectively removing a portion of the diblock copolymer;
patterning the first metal layer using a remaining portion of the diblock copolymer;
depositing a dielectric layer over the first metal layer;
depositing a second metal layer over the dielectric layer to form a metal-insulator-metal (MIM) device; and
coupling a third metal layer between the first metal layer and the dielectric layer, the third metal layer at least partially comprising a lower electrode;
wherein the first metal layer is coupled with the dielectric layer only indirectly through one or more other elements.
2. The method of claim 1 , wherein the first metal layer at least partially comprises the lower electrode.
3. The method of claim 1 , wherein the second metal layer is an upper electrode.
4. The method of claim 1 , wherein the first metal layer is a seed layer.

patterning the first metal layer using a remaining portion of the diblock copolymer;
depositing a dielectric layer over the first metal layer; and
depositing a second metal layer over the dielectric layer to form a metal-insulator-metal (MIM) device.
7. The method of claim 6 , further comprising coupling a third metal layer between the first metal layer and the dielectric layer, the third metal layer at least partially comprising a lower electrode.
