[0043] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices and / or systems described herein. However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, which is not limited to the order set forth herein, but in addition to the operations that must occur in a specific order, changes that will be apparent after understanding the disclosure of the present application can be made. In addition, in order to improve clarity and brevity, the description of features known in the art can be omitted. The features described herein can be implemented in different forms and should not be construed as being limited to the examples described herein. More specifically, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application. Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements between them. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements between them. As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more items. Although terms such as "first", "second", and "third" may be used here to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. More precisely, these terms are only used to distinguish a member, component, region, layer or part from another member, component, region, layer or part. Therefore, without departing from the teaching of the example, the first member, component, region, layer or part referred to in the example described here may also be referred to as the second member, component, region, layer or part. For ease of description, spatial relationship terms such as "above ... ", "upper", "below ... " and "lower" can be used here to describe the relationship between an element and another element as shown in the drawings. Such spatial relationship terms are intended to include different orientations of the device in use or operation in addition to being included in the orientation depicted in the drawings. For example, if the device in the drawings is flipped, the element described as being "above" or "upper" relative to another element will then be located "below" or "lower" relative to another element.Therefore, the term "above" includes two orientations, "above" and "below" according to the spatial orientation of the device. The device can also be positioned in other ways (for example, rotated 90 degrees or in other orientations), and the spatial relationship terms used here will be interpreted accordingly. The terms used here are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "include", "comprise" and "have" list the stated features, quantities, operations, components, elements and / or their combinations, but do not exclude the existence or addition of one or more other features, quantities, operations, components, elements and / or their combinations. Due to manufacturing technology and / or tolerances, changes in the shapes shown in the drawings may occur. Therefore, the examples described here are not limited to the specific shapes shown in the drawings, but include changes in shapes that occur during manufacturing. The features of the examples described here can be combined in various ways that will be obvious after understanding the disclosure of the present application. In addition, although the examples described here have various configurations, other configurations are possible as will be obvious after understanding the disclosure of the present application.
