Embodiment Construction

[0061] In order to illustrate the present application more clearly, the present application will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present application.

[0062] It should be noted that "on", "formed on" and "arranged on" mentioned in this article may mean that one layer is directly formed or set on another layer, or that a A layer is indirectly formed or disposed on another layer, ie there are other layers between the two layers. In this document, unless otherwise specified, the term "on the same layer" used means that two layers, parts, members, elements or parts can be formed by the same patterning process, and that the two layers, parts, members, Elements or parts...
