Abstract

The invention provides a logic device and a manufacturing method thereof. The logic device comprises a substrate, a heavy metal layer, a ferromagnetic layer, a multiferroic layer and an oxide layer, wherein the heavy metal layer comprises a cross structure of which the outer side is provided with a corresponding electrode; and the resistance of the heavy metal layer is changed by changing the direction of an electric field applied between the oxide layer and the heavy metal layer. Specifically, the substrate is a flexible substrate, and has the advantages of being resistant to extrusion, bendable and the like; and the control of the electric field on a critical current of spin-orbit coupling is realized at the room temperature through a multiferroic material, so that a spin-orbit coupling signal is effectively controlled. The effect of the logic device is changed by using different oxidation state interfaces (oxide layers), and the control of an input voltage on the critical current of the spin-orbit coupling makes a difference, so that an N-type or P-type logic operation function can be achieved; the light, portable and low-power logic device can be obtained; and logic devices can also be combined to obtain a logic assembly integrating N-type and P-type logic functions.

Description

technical field [0001] The invention relates to the technical field of microelectronics, in particular to a logic device based on multiferroic magnetoelectric coupling and spin-orbit coupling effects and a manufacturing method thereof. Background technique [0002] Traditional electronics is based on the charge properties of electrons, and people realize information storage and logic processing through the control of electronic charges. However, with the gradual miniaturization of electronic devices, the influence of quantum effects and energy loss is becoming more and more obvious, and traditional electronic devices can no longer meet the needs of development. [0003] The advantages of spintronic devices such as non-volatility, low energy consumption and high integration make them develop rapidly. The high computing power and low energy consumption of spintronic devices in information processing are incomparable to traditional semiconductor electronic devices. Spin-orbit ...
