具体实施方式
现在将参照附图更全面地描述示例实施方式。提供示例实施方式以使得本公开内容将是透彻的并将其范围完全传达给本领域技术人员。阐述了许多具体细节例如具体部件、设备和方法的示例以提供对本公开内容的实施方式的透彻理解。对于本领域技术人员将明显的是，不需要采用具体细节，就可以以许多不同的形式来体现示例实施方式并且这些不同的形式都不应当被解释为限制本公开内容的范围。在一些示例实施方式中，未详细描述公知的过程、公知的设备结构和公知的技术。
本文使用的术语仅出于描述特定示例实施方式的目且不旨在进行限制。如本文所使用的，除非上下文另外明确指出，否则单数形式“一”，“一个”和“该”也可以旨在包括复数形式。术语“包含(comprises)”，“包含(comprising)”，“包括(including)”和“具有”是包含性的，因此指定存在所述特征、整数、步骤、操作、元件和/或部件，但不排除存在或添加一个或更多个其他特征、整数、步骤、操作、元件、部件和/或其群组。除非明确地标识为执行顺序，否则本文描述的方法步骤、过程和操作不应被解释为必须以所讨论或示出的特定顺序执行。还应理解，可以采用附加步骤或替选步骤。
当一个元件或层被称为在另一元件或层“上”，“接合至”、“连接至”或“耦接至”另一元件或层时，它可以直接位于另外的元件或层上，接合、连接或耦接至另外的元件或层，或者可以存在中间元件或层。相比之下，当元件被称为“直接在”另一元件或层“上”、“直接接合至”、“直接连接至”或“直接耦接至”另一元件或层时，可能不存在中间元件或层。应当以类似的方式来解释用于描述元件之间的关系的其他词语(例如，“在...之间”与“直接在...之间”、“相邻”与“直接相邻”等)。如本文所使用的，术语“和/或”包括一个或更多个相关联的所列项目的任何组合和所有组合。
尽管本文可以使用术语第一、第二、第三等来描述各种元件、部件、区域、层和/或部分，但是这些元件、部件、区域、层和/或部分不应受到这些术语限制。这些术语可以仅用于对一个元件、部件、区域、层或部分与另一区域、层或部分进行区分。除非上下文明确指出，否则诸如“第一”、“第二”和其他数字术语的术语在本文中使用时并不隐含顺序或次序。因此，在不脱离示例实施方式的示教的情况下，下面讨论的第一元件、第一部件、第一区域、第一层或第一部分可以被称为第二元件、第二部件、第二区域、第二层或第二部分。
为了便于描述，在本文中可以使用空间相对术语例如“内部”、“外部”、“在……之下”、“在……下方”、“在……下部”、“在……上方”、“在……上部”等来描述如附图所示的一个元件或特征与另一元件或特征的关系。除了附图中描绘的方位之外，空间相对术语还可以旨在涵盖设备在使用或操作中的不同方位。例如，如果附图中的设备被翻转，则被描述为在其他元件或特征“下方”或“之下”的元件将被定向为在所述其他元件或特征“上方”。因此，示例术语“在……下方”可以包括“在……上方”和“在……下方”两个方位。可以以其他方式来定向(旋转90度或在其他方位处)设备，并相应地解释本文所使用的空间相对描述语。
