Abstract

The invention provides a Schottky rectifier tube manufacturing method and a Schottky rectifier tube, the Schottky rectifier tube comprises a first packaging shell, a second packaging shell, a first terminal, a second terminal, a third terminal and a Schottky chip, the first packaging shell is connected with the second packaging shell in a buckling mode, the first terminal, the second terminal and the first packaging shell are integrally formed, and the Schottky chip is arranged in the first packaging shell. And the third terminal and the second packaging shell are integrally formed. According to the Schottky rectifier tube manufacturing method and the Schottky rectifier tube, the Schottky rectifier tube can be manufactured through the procedures of punching forming, injection molding, chip fixing and buckling forming, the structure is simple, the number of steps is small, and the manufacturing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of Schottky rectifiers, in particular to a method for manufacturing a Schottky rectifier and the Schottky rectifier. Background technique [0002] Schottky rectifier is a metal-semiconductor device made of noble metal (gold, silver, aluminum, platinum, etc.) A as the positive electrode and N-type semiconductor B as the negative electrode. . Because there are a large number of electrons in the N-type semiconductor and only a small amount of free electrons in the noble metal, the electrons diffuse from B with high concentration to A with low concentration. Obviously, there are no holes in metal A, and there is no diffusion of holes from A to B. As electrons continue to diffuse from B to A, the electron concentration on the surface of B gradually decreases, and the surface electrical neutrality is destroyed, thus forming a potential barrier, and its electric field direction is B→A. However, under the action ...
