The device comprises a semiconductor substrate, and a source electrode, a drain electrode, a source doping region, a tunneling insulator layer and a metal layer positioned on the semiconductor substrate; an MIS (Management Information System) structure consists of the metal layer, the tunneling insulator layer and the semiconductor substrate; and the device further comprises a grid insulator layer and a grid electrode positioned on the grid insulator layer for surrounding the MIS structure in a circle. In the invention, the fence-type grid-controlled metal-insulator device based on electronic tunneling effect is manufactured with platform technology, and the grid electrode surrounds the metal-insulator structure in a circle for enhancing the control ability of the grid electrode; and simultaneously, proper bias voltage is applied on the fence-type grid-controlled metal-insulator device so as to control the tunneling efficiency, decrease the leakage current and improve the sub-threshold swing amplitude performance.

Description

technical field [0001] The invention belongs to the technical field of quantum effect devices, and in particular relates to a gate-enclosed gate-controlled metal-insulator device based on electron tunneling. 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 nanomete...
