[0049] Hereinafter, the embodiments of the present disclosure will be described more comprehensively with reference to the accompanying drawings showing various embodiments. However, the embodiments can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Throughout the specification, similar reference numerals indicate similar elements.

[0050] It should be understood that when an element such as a layer, region, or substrate is referred to as being "on" another element, the element can be directly on the other element, or there can be intervening elements. In contrast, the term "directly" means that there are no intervening elements. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0051] The professional terms used herein are only for the purpose of describing various embodiments and are not intended to be limiting. Unless the content clearly states otherwise, the singular forms "a", "an" and "the" as used herein are intended to include plural forms including "at least one". For the purpose of its meaning and interpretation, in the specification and claims, the phrase "at least one" is intended to include the meaning of "at least one selected from a cluster of..." For example, "at least one of A and B" may be understood to mean "A, B or A and B". Multiple For the purpose of its meaning and interpretation, in the specification and claims, the term "and / or" is intended to include any combination of the terms "and" and "or". For example, "A and / or B" may be understood to mean "A, B or A and B". The terms "and" and "or" may be used in combination or separation, and may be understood to be equivalent to "and / or". It will also be understood that the terms “comprises” and / or “comprising”, when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components and / or clusters thereof.

[0052] Spatially relative terms such as "beneath", "below", "lower", "above", and "upper" may be used herein for ease of description to describe the relationship of one element or feature to another element or feature as shown in the figures. It will be understood that, in addition to the orientations shown in the drawings, spatially relative terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is turned over, the elements described as being "below" or "beneath" other elements or features will then be oriented to be above the other elements or features. Therefore, the exemplary term "below" may include both the orientations of above and below. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0053] It will be understood that, for example, although a plurality of terms first, second and third may be used in this article to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, the first element, component, region, layer or part discussed below may be referred to as the second element, component, region, layer or part without departing from the teachings herein.

[0054] As used herein, "about" or "approximately" includes the stated value and mean within an acceptable range of deviation for a particular value as determined by one of ordinary skill in the art, taking into account the measurements in question and errors associated with measurement of the particular quantity (e.g., limitations of the measurement system).

[0055] Embodiments are described herein with reference to schematic cross-sectional views and / or plan views as exemplary illustrations. In the accompanying drawings, the thickness of layers and regions may be exaggerated for clarity. Accordingly, variations in the shapes of the illustrations resulting from, for example, manufacturing techniques and / or tolerances are expected. Therefore, embodiments should not be interpreted as being limited to the shapes of the regions shown herein, but will include deviations in shapes resulting from, for example, manufacturing. For example, an etched region shown as a rectangle will typically have circular or curved features. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the actual shapes of the regions of the device and are not intended to limit the scope of the embodiments.

[0056] In addition, the term "overlap" or "overlapped" means that the first object may be located above or below the second object or on one side of the second object, and vice versa. Additionally, the term "overlap" may include layers, stacks, facing or facing, extending above, covering or partially covering, or any other suitable terms that a person of ordinary skill in the art will recognize and understand. The terms "facing" and "facing" mean that the first element may be directly or indirectly opposite to the second element. In the case where a third element is between the first element and the second element, although still facing each other, the first element and the second element may be understood to be indirectly opposite to each other. When an element is described as "non-overlapping" or "not overlapping" with another element, this may include elements being spaced apart from each other, offset from each other, or separated from each other, or any other suitable terms that a person of ordinary skill in the art will recognize and understand.

[0057] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. It will also be understood that, unless expressly defined in this specification, terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and will not be interpreted in an ideal or overly formal sense.
