Grid-control metal-insulator device based on electronic tunneling

Abstract

The invention belongs to the technical field of quantum effect devices, and in particular relates to a grid-control metal-insulator device based on electronic tunneling. The grid-control metal-insulator device based on the electronic tunneling comprises a semiconductor substrate, a grid, a grid insulator layer, and a source, a drain, a source doping area, a tunneling insulator layer and a metal layer which are positioned on the semiconductor substrate, wherein the metal layer, the tunneling insulator layer and the semiconductor substrate form a metal-insulator-semiconductor (MIS) structure; the grid is positioned on one side of the MIS structure on the semiconductor substrate; and the grid insulator layer is positioned between the MIS structure and the grid. A metallic oxide semiconductorfield effect transistor (MOSFET)-like (MOS-like) device based on a quantum tunneling effect is manufactured by a platform process; and by applying proper biasing pressure on the MOS-like device, the tunneling effect of the MOS-like device can be controlled, reverse current is reduced and sub-threshold amplitude performance is improved.

Description

technical field [0001] The invention belongs to the technical field of quantum effect devices, and in particular relates to a semiconductor device based on the quantum tunneling effect. Background technique [0002] In recent years, microelectronics technology with silicon integrated circuits as the core has developed rapidly. As one of the important indicators to measure the development of integrated circuits, the degree of integration basically follows Moore's law, that is, the degree of integration of semiconductor chips doubles every 18 months, which requires continuous reduction in the size of devices. In the process of shrinking the characteristic size of semiconductor devices, when the characteristic size of the chip is in the micron scale, the electrons in it are mainly particle in the wave-particle duality. At present, most semiconductor devices only use the particle of electrons; when the chip's When the characteristic size is at the nanometer scale, especially wh...
