However, various changes, modifications and equivalents of the methods, apparatus and/or systems described herein will be apparent after understanding the disclosure of the present application. For example, the order of operations described herein is merely an example and is not limited to the order set forth herein, but rather than operations that must occur in a particular order, may be made that will become apparent upon understanding the disclosure of the present application change. Also, descriptions of features known in the art may be omitted for increased clarity and conciseness.

The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, 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 an understanding of the disclosure of the present application.

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

As used herein, the term "and/or" includes any and any combination of any two or more of the associated listed 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 are not subject to these terms restricted. Rather, these terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, reference to a first element, component, region, layer or section in the examples described herein could be termed a second element, component, region, layer or section without departing from the teachings of the examples.

For ease of description, spatially relative terms such as "above", "upper", "under", and "lower" may be used herein to describe one element as shown in the figures to another element relationship. 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 being "on" or "upper" relative to another element would then be oriented "below" or "lower" relative to the other element. Thus, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may also be otherwise oriented (eg, rotated 90 degrees or at other orientations) and the spatially relative terms used herein interpreted accordingly.

The terminology used herein is used to describe various examples only, and not to limit the present disclosure. Singular forms are intended to include plural forms as well, unless the context clearly dictates otherwise. The terms "comprising", "comprising" and "having" enumerate the presence of stated features, quantities, operations, components, elements and/or combinations thereof, but do not preclude the presence or addition of one or more other features, quantities, operations, components, elements and/or combinations thereof.
