具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
将理解，当一个元件或层被称为在另一元件或层“上”、“连接到”或“耦接到”另一元件或层时，它可以直接在另一元件或层上、直接连接到或耦接到另一元件或层，或者可以存在居间元件或层。相反，当一个元件被称为“直接在”另一元件或层上、“直接连接到”或“直接耦接到”另一元件或层时，不存在居间元件或层。相同的符合标记始终指代相同的元件。在此所用时，术语“和/或”包括一个或多个相关列举项目的任何及所有组合。
将理解，虽然这里可以使用术语第一、第二等描述各种元件、组件、区域、层和/或部分，但这些元件、组件、区域、层和/或部分不应受到这些术语限制。这些术语仅用于将一个元件、组件、区域、层或部分与另一元件、组件、区域、 层或部分区别开。因此，以下讨论的第一元件、组件、区域、层或部分可以被称为第二元件、组件、区域、层或部分而不背离本发明的教导。
为便于描述，这里可以使用诸如“在…之下”、“在…下面”、“下”、“在…之上”、“上”等空间相对性术语来描述如图中所示的一个元件或特征与另一个(些)元件或特征的关系。将理解，空间相对性术语旨在涵盖除图中示出的取向之外，器件在使用或操作中的不同取向。例如，如果附图中的器件被翻转，则被描述为“在”其他元件或特征“之下”或“下面”的元件将会在其他元件或特征“上方”。因此，示例性术语“在…下面”可以涵盖之上和之下两种取向。器件可以以别的方式取向(旋转90度或其他取向)，这里所用的空间相对性描述符被相应地解释。
这里所用的术语仅是为了描述特定实施例，并非要限制本发明。在这里使用时，除非上下文另有明确表述，否则单数形式“一”和“该”也旨在包括复数形式。将进一步理解，当在本说明书中使用时，术语“包括”和/或“包含”表明所述特征、整体、步骤、操作、元件和/或组件的存在，但不排除一个或多个其他特征、整体、步骤、操作、元件、组件和/或其组合的存在或增加。
除非另行定义，这里使用的所有术语(包括技术术语和科学术语)都具有本发明所属领域内的普通技术人员所通常理解的相同含义。将进一步理解，诸如通用词典中所定义的术语，否则应当被解释为具有与它们在相关领域的语境中的含义相一致的含义，而不应被解释为理想化或过度形式化的意义，除非在此明确地如此定义。
