[0024] The features described herein can be implemented in different forms and should not be construed as limited to the examples described herein. Rather, these examples have been provided so that this disclosure will be thorough and complete, and will fully convey the scope of the methods, apparatuses, and / or systems to those skilled in the art. Further, the description should not be interpreted as a general abatement of equivalents or other claims.
[0025] Throughout the specification, when an element (such as a layer, region, or substrate) is referred to as being "on" another element, "connected to" another element, "coupled to" another element, "adjacent to" another element, or "covering" another element, it can be directly on, connected, coupled, adjacent to, or covering the other element or one or more other elements can be interposed therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to," "directly coupled to," "directly adjacent to," or "directly covering" another element, there are no other elements interposed therebetween.
[0026] As used herein, the term "and / or" includes any one of the listed items and any combination of any two or more of the listed items.
[0027] Although terms such as "first" and "second" and "third" can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / 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, elements, components, regions, layers and / or sections described herein as being called a first element, component, region, layer or section can also be called a second element, component, region, layer or section, without departing from the teachings of the examples.
[0028] For ease of description, spatial terms such as "over," "upper," "under," and "lower" can be used with respect to the orientation of one element relative to another element as illustrated in the figures. Such spatial terms can be 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, then an element described as being "over" or "upper" relative to another element would then be oriented "under" or "lower" relative to the other element. Accordingly, the term "over" encompasses both an "over" and "under" orientation depending on the spatial orientation of the device. The device can be oriented in other ways (e.g., rotated 90 degrees or at other orientations) and an appropriate recitation of the spatial terms used herein will be made accordingly.
[0029] The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting of the present disclosure. As used herein, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "includes," "including" and "has," "having" and the like are inclusive of the stated features, numbers, operations, components, elements and / or the like, but do not exclude the presence or addition of one or more other features, numbers, operations, components, elements and / or the like.
[0030] Variations in shapes depicted in the figures can occur as a result of manufacturing processes and / or tolerances. Thus, the examples described herein are not limited to the precise shapes shown in the figures, but include variations in shapes that would occur as a result of manufacturing processes.
[0031] Features of the examples described herein can be combined with one another as would be apparent to one of ordinary skill in the art after having the benefit of the present disclosure.
