Part is etched, and partially remains on substrate, to keep contact area of the sinter layer when substrate package is in cover board larger；Using
Wet-etching technology carries out laterally etched on third interlayer insulating film, and to form sidewall notches, sinter layer and third interlayer are exhausted
The contact area of the side wall of edge layer is larger, thereby may be ensured that sinter layer using ordinary sinter material be packaged can reach it is pre-
Fixed adhesive strength solves due to the agglomerated material without higher bond degree and is easy cracking at the encapsulation of display equipment
And the problem that service life is lower.
For example, the second interlayer insulating film is single layer film quality structure, and the material of single layer film quality structure is moisture-resistant liquid etching
Material can be etched during wet etching to avoid insulating layer between the second layer.It is appreciated that in other embodiments, the
Two interlayer insulating films can also be lamination film quality structure, and one layer of insulating layer between the second interlayer insulating film adjacent first layer
Material be moisture-resistant liquid etching material, can be etched completely during wet etching to avoid insulating layer between the second layer.Example
Such as, the moisture-resistant liquid etch layer is with the structure sheaf for resisting wet liquid etching corrosion.For example, the material of wet liquid etching liquid includes
But it is not limited only to hydrofluoric acid.
For example, the third interlayer insulating film is lamination film quality structure, and the top layer of the third interlayer insulating film is anti-
Wet liquid etch layer, the material of moisture-resistant liquid etch layer be the material of moisture-resistant liquid etching, i.e. third interlayer insulating film deviates from the second layer
Between one layer of the insulating layer material layers for moisture-resistant liquid etching, can be complete during wet etching to avoid insulating layer between third layer
Full etching.For another example, the material of wet liquid etching liquid includes but are not limited to hydrofluoric acid.
