Abstract

The invention provides a bias frequency mixing Schottky diode structure and a semiconductor device, and belongs to the technical field of semiconductor devices. The bias frequency mixing Schottky diode structure comprises a first metal electrode and a second metal electrode, the second metal electrode is divided into an upper sub-electrode and a lower sub-electrode, a first Schottky junction is connected between the first metal electrode and the upper sub-electrode, and the second Schottky junction is reversely connected in parallel between the first metal electrode and the lower sub-electrode. According to the bias frequency mixing Schottky diode structure provided by the invention, the two Schottky junctions are connected in parallel reversely, one ends of the Schottky junctions are connected with the same metal electrode, and the other ends of the Schottky junctions are connected with the two disconnected metal electrodes so that the diode can be biased, and the requirement of a frequency mixer on local oscillation power is reduced; and the difficulty of a local oscillation source is decreased.

Description

technical field [0001] The invention belongs to the technical field of semiconductor devices, and more specifically relates to a biasable frequency mixing Schottky diode structure and a semiconductor device. Background technique [0002] Terahertz (THz) waves refer to electromagnetic waves with a frequency in the range of 0.3-3THz, between millimeter waves and infrared light. THz waves occupy a very special position in the electromagnetic wave spectrum. They have the characteristics of high frequency, wide bandwidth, and good safety. They are widely used in security inspection, communication, radar, and radio astronomy. [0003] The key to researching terahertz electronic systems is terahertz transmitting and receiving technology. In the terahertz frequency band, due to the lack of corresponding low-noise amplifiers, the terahertz mixer has become the first stage of the receiving end of the electronic system, and its indicators directly affect the performance of the entire ...
