Abstract
Some implementations described herein provide techniques and apparatuses for forming a semiconductor device including a metal-insulator-metal capacitor. The metal-insulator-metal capacitor includes a dielectric pad layer having a portion between a capacitor bottom metal electrode layer and a portion of an insulator layer. The dielectric pad layer may preserve a thickness of the insulator layer to reduce a likelihood of a leakage between a capacitor top metal electrode layer and the capacitor bottom metal electrode layer. The dielectric pad layer may also enable a reduction in a thickness of the insulator layer to increase a capacitance of the metal-insulator-metal capacitor.
