Title:
METHOD FOR MANUFACTURING SEMICONDUCTOR INK AND METHOD FOR MANUFACTURING DIODE AND RECTIFIER CIRCUIT USING SEMICONDUCTOR INK
Document Type and Number:
WIPO Patent Application WO/2019/107642
Kind Code:
A1
Abstract:
The method for manufacturing a semiconductor ink according to the present invention comprises the steps of: manufacturing inorganic oxide semiconductor powder by drying an inorganic oxide semiconductor in a gel state, and then sintering same at a preset temperature; and mixing and dispersing the inorganic oxide semiconductor powder in a polystyrene sulfonic acid (PSSA) solution. The PSSA included in the semiconductor ink manufactured according to the present invention functions as an electron activation binder and provides viscosity and colloidal stability to the semiconductor ink, and, at the same time, when being manufactured into a diode, allows mobile interfacial electrons to be transferred efficiently.
