Embodiment Construction

[0023] The substantive features and remarkable progress of the present invention will be further described below through the elaboration of specific embodiments.

[0024] Al-doped ZnO film (AZO) is selected as the electrode layer, and the general molecular formula is Al x Zn 1-x O, (0.02-4 ~9×10 -4 Ohm cm; Mg-doped ZnO thin film (MZO) is selected as the resistive layer, and the molecular formula is Mg y Zn 1-y O, (0.13 times. A zinc oxide-based homogeneous structure transparent RRAM component constructed from the electrode layer and the resistive switch layer is characterized in that the bottom electrode layer AZO (2) is sequentially deposited on the substrate (1), and the middle resister Variable layer MZO (3), top electrode AZO (4). Made by pulsed laser deposition (PLD), the specific process steps are as follows:

[0025] 1) The substrate is made of quartz glass (1), which is ultrasonically cleaned with acetone, ethanol and deionized water;

[0026] 2) Using a ZnO cer...

Abstract

The invention relates to a zinc oxide-based homogeneous structure transparent resistive random access memory (RRAM) component and a manufacturing method. The storage element is composed of a sandwich structure of "electrode layer / resistance variable oxide layer / electrode layer" prepared in sequence on a quartz glass substrate. Wherein, the material of the electrode layer is a ZnO-based doped transparent conductive film, and the material of the resistive switch oxide layer is ZnO or a ZnO-based doped resistive thin film. On the premise of maintaining the transparency of the material, by adjusting the components of the ZnO-based thin film, the conductivity and resistance transition performance of the thin film material are controlled, so as to achieve the purpose of stable storage. The biggest advantage of the memory cell structure of the present invention is that it is based on low-cost zinc oxide-based homogeneous structure film materials, and a homogeneous RRAM memory cell structure with stable performance and good transparency is obtained through doping control, which is beneficial to RRAM memory devices Develop towards low-cost, high-performance transparent devices.
