Publication number: 20230361164Abstract: Some implementations described herein provide a semiconductor device and methods of formation. The semiconductor device may include a photodiode device electrically connected to a metal-insulator-metal deep-trench capacitor. The metal-insulator-metal deep-trench capacitor includes a layer of an amorphous material between an insulator layer stack of the deep-trench capacitor structure and a capacitor bottom metal layer of the metal-insulator-metal deep-trench capacitor. The amorphous material includes a bandgap energy level that provides a conduction band offset and lowers a probability of electron tunneling from the capacitor bottom metal electrode layer to the insulator layer stack. In this way, leakage associated with grain boundaries, crystal defects, and interfaces of a bottom layer of the insulator layer stack may be overcome to improve a lag performance of the semiconductor device including the metal-insulator-metal deep-trench capacitor.Type: ApplicationFiled: May 9, 2022Publication date: November 9, 2023Inventors: Min-Ying TSAI, Chih-Ping CHANG, Ching I LI
