Abstract |
The double layers of SiO_2/Si_3N_4 have superior charge storage stability than a single layer of SiO_2. Many researchers are very interested in the charge storage mechanism of SiO_2/Si_3N_4 [1,2]. In this paper, the electrical characteristics of thermal oxide and atmospheric pressure chemical vapor deposition (APCVD) of Si_4N_4 have been investigated and explained using high frequency capacitance-voltage measurements. Additionally, this paper will describe capacitance-voltage characteristics for double layers of SiO_2/Si_4N_4 by "Athena", a semiconductor device simulation tool created by Silvaco, Inc.vaco, Inc. |
