Skeparovski; D. Spassov; A. Paskaleva; N. Novkovski | Issue Date: | 14-Dec-2017 | Publisher: | IEEE | Conference: | 2017 IEEE 30th International Conference on Microelectronics (MIEL) | Abstract: | Charge trapping properties of Al-ZrO 2 /Al 2 O 3 /ZrO 2 -SiO 2 -Si structures were investigated in attempt to elucidate the instability in their C-V hysteresis. The hysteresis in these structures is mainly due to subsequent trapping of electrons and holes injected from the Si substrate. However the competitive process of electron injection from the gate accompanied by the high leakage introduces instability and compromises the memory window. | URI: | http://hdl.handle.net/20.500.12188/11508 | DOI: | DOI: 10.1109/MIEL.2017.8190073 |
