Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

In the entire specification, when an element such as a layer, region, or substrate is described as being "on," "connected to," coupled to, "on," or "covering" another element, it may be directly "on," "connected to," coupled to, "on," or "covering" another element, or there may be one or more other elements interposed therebetween. In contrast, when an element is referred to as being "directly on," directly connected to, "or" directly coupled to, "another element, directly on," or "directly covering" the other element, there may be no other element intervening therebetween.

As used herein, the term "and/or" includes any one of the listed items of interest and any combination of any two or more.

Although terms such as "first," "second," and "third" may be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections should not be limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first member, component, region, layer or section discussed in examples described herein could also be termed a second member, component, region, layer or section without departing from the teachings of the examples.

For ease of description, spatially relative terms such as "above … …," "upper," "below … …," and "lower" may be used herein to describe one element's relationship to another element as illustrated in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "upper" relative to another element would then be oriented "below" or "lower" relative to the other element. Thus, the term "above … …" includes both orientations "above … …" and "below … …" depending on the spatial orientation of the device. The device may also be otherwise oriented, e.g., rotated 90 degrees or at other orientations, and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting of the disclosure. Singular forms also are intended to include plural forms unless the context clearly indicates otherwise. The terms "comprises," "comprising," and "having" are intended to specify the presence of stated features, integers, operations, elements, and/or groups thereof, but do not preclude the presence or addition of one or more other features, integers, operations, elements, and/or groups thereof.

Variations from the shapes of the illustrations as a result, of manufacturing techniques and/or tolerances, are to be expected. Accordingly, the examples described herein are not limited to the particular shapes shown in the drawings, but include changes in shapes that occur during manufacture.

The features of the examples described herein may be combined in various ways that will be apparent upon an understanding of the present disclosure. Further, while the examples described herein have a variety of configurations, other configurations are possible as will be apparent after an understanding of the present disclosure.
