Description

Can improve coiling mechanism of dyne value of ITO membrane

[ technical field ] A method for producing a semiconductor device

The utility model relates to a technical field of ITO membrane, especially a can improve technical field of the coiling mechanism of the dyne value of ITO membrane.

[ background of the invention ]

An ITO (indium tin oxide) film is an n-type semiconductor material, and has high electrical conductivity, high visible light transmittance, high mechanical hardness, and good chemical stability.

As shown in fig. 1, the conventional ITO film mainly includes a PP or PE protective film a, an ITO plating layer b, a PET main film c, and a PET high temperature protective film d, which are sequentially disposed from top to bottom. The PP or PE protective film a can protect the ITO plating layer b. If the PP or PE protective film a is not coated, the ITO plating layer b may be scratched or stained during slitting, packaging, transportation, or the like, and thus the PP or PE protective film a is required to be coated.

In a process of manufacturing a TP (touch panel) using an ITO film, it is necessary to print silver paste on the ITO surface of the ITO film. Therefore, a higher adhesion between the silver paste and the ITO side is required. The general parameter of low adhesion is the surface tension of the ITO film, i.e., the dyne value of the ITO face. The physical properties of ITO itself are expressed as high dyne values (around 40). However, when the PP or PE protective film a is coated on the ITO film, the small molecules of the glue on the PP or PE protective film a are adsorbed on the ITO surface, and the dyne value of the ITO surface of the ITO film is significantly decreased, and the longer the time, the lower the dyne value. Tests show that the dyne value of the ITO surface of the ITO film is lower than 32 after the PP or PE protective film a is coated for 20-30 days, so that the possibility of silver paste falling off is high after silver paste is printed.
