Production method of high stability trigger diode

Abstract

The invention relates to a production method of a high stability trigger diode, comprising the steps of welding, primary acid washing, high purity water flushing, secondary acid washing, high purity water flushing, two times of high purity water ultrasonic cleaning, two times of anhydrous ethanol cleaning, gluing, plastic injection moulding and the like; an inlet of a welding furnace is designed in an upslope structure form while an outlet thereof is designed in a downslope structure form, so the use quantity of protective gas, i.e., nitrogen during welding is decreased obviously; and the consumption of energy resources is reduced; the traditional scattering method is changed to a method of putting in acid liquid in fixed points in a concentrated manner; thus the consumption of acid is reduced; the pollution to the environment is reduced at the same time; and the corrosion to copper leads is reduced; the impurities can be effectively removed in a manner of flushing through sector nozzles in the cleaning process; and the high temperature performance of products is greatly improved by using two times of high purity water ultrasonic cleaning and two times of anhydrous ethanol cleaning.

Description

technical field [0001] The invention relates to the manufacture of semiconductor diodes, in particular to a method for manufacturing high-stability trigger diodes. Background technique [0002] After retrieving relevant patent documents, a manufacturing method of a highly stable trigger diode identical to the present invention has not yet been retrieved. With the advancement of science and technology, the electrical industry is developing towards high integration and high power, which puts forward higher requirements for the quality of diodes. Existing trigger diodes are generally manufactured by multiple times of glass firing and photolithography. Due to the high requirements on the environment and high cost in the manufacturing process, the performance reliability of the produced trigger diodes is low, and Due to the large amount of protective nitrogen used in the production process, it consumes a lot of energy; at the same time, due to production process problems, the pe...

Problems solved by technology

Existing trigger diodes are generally manufactured by multiple times of glass firing and photolithography. Due to the high requirements on the environment and high cost in the manufacturing process, the performance reliability of the produced trigger diodes is low, and Due to the large amount of protective nitrogen used in the production process, it consumes a lot of energy; at the same time, due to production process problems, the performance of the produced trigger diodes is not stable enough at high temperature, so it is necessary to modify the existing production of trigger diodes.
