Patent ID: 11901402
Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 16:
17. A method of manufacturing an electronic device, the method comprising:
fabricating a capacitor die, including:
forming a first dielectric layer above a semiconductor layer of a wafer;
forming a lower-bandgap dielectric layer above the first dielectric layer, the lower-bandgap dielectric layer having a bandgap energy less than a bandgap energy of the first dielectric layer;
forming a conductive first capacitor plate above the lower-bandgap dielectric layer;
forming a second dielectric layer above the first capacitor plate; and
forming a conductive second capacitor plate and a conductive third capacitor plate above the second dielectric layer; and

separating the capacitor die from the wafer.
