Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and/or systems described herein that will be apparent upon understanding the present disclosure.

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

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

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.
