[0027] The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related content, and not to limit the present disclosure. In addition, it should be noted that only parts related to the present disclosure are shown in the drawings for ease of description.

[0028] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Unless otherwise indicated, the exemplary implementations / examples will be understood to provide exemplary features of various details of some ways in which the inventive concepts of the present disclosure can be implemented in practice. Thus, unless otherwise indicated, the features of the various implementations / examples can be combined, separated, interchanged, and / or rearranged, additionally, without departing from the inventive concepts of the present disclosure.

[0030] The use of cross-hatching and / or shading in the drawings is generally used to indicate different regions within the same component and is not intended to indicate specific materials, material properties, dimensions, ratios, etc. Moreover, the use of same reference numerals in different figures indicates similar and / or identical components.

[0031] When a component is referred to as being "on" or "over", "connected to", or "coupled to" another component, it can be directly on, connected, or coupled to the other component, or intervening components can be present. When a component is referred to as being "directly on", "directly connected to", or "directly coupled to" another component, there are no intervening components present. By the term "connected" is meant to include physical or electrical connections, with or without intervening components.

[0032] For descriptive purposes, the disclosure can use spatial or directional adjectives, such as "under", "below", "lower", "on", "above", "upper", "over", "higher", and "side" (e.g., in "sidewall"), to describe the relationship between one component and another (s) as shown in the drawings. The spatial or directional adjectives are intended to encompass different orientations of the device in use, operation, and / or manufacture, other than the orientation depicted in the drawings. For example, if the device in the drawings were turned over, then a component described as "below" or "under" another component would then be oriented "above" the other component. Thus, the exemplary term "below" can encompass both an orientation of above and of below. Moreover, the device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatial or directional adjectives used herein interpreted accordingly.

[0033] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. 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. Furthermore, to the extent that the terms "comprise," "include," "contain," and / or "comprising," "including," and / or "contain" are used in the detailed description and / or claims, such terms are intended to be inclusive in a manner similar to that of the terms "comprise" and / or "include" and / or "including" as an open transition term without limiting. It is also noted that, as used herein, the terms "substantially," "approximately," and other similar terms are used as synonyms for "about," and are intended to mean that a value is within a reasonable expected range of values (i.e., a range that would be understood by one of ordinary skill in the art to be acceptable under the circumstances) when used in a description of a parameter, property, or condition.
