  • a surface can be deemed to be planar or basically planar if a displacement between any two points on the surface with respect to a plane is no greater than 5 ⁇ m, no greater than 2 ⁇ m, no greater than 1 ⁇ m, or no greater than 0.5 ⁇ m.
  • conductive As used herein, the terms “conductive”, “electrically conductive” and “electrical conductivity” refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m). Typically, an electrically conductive material is a material having a conductivity greater than approximately 10 4 S/m (such as at least 10 5 S/m or at least 10 6 S/m). The electrical conductivity of a material is can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.
  • assemblies provided “on” or “above” another component may encompass a case in which a previous component is directly on a latter component (for example, in physical contact with the latter component), and a case in which one or more intermediate assemblies are located between the previous component and the latter component.
  • space-related terms such as “under”, “below”, “lower portion”, “above”, “upper portion”, “lower portion”, “left side”, “right side”, and the like may be used herein to describe a relationship between one component or feature and another component or feature as shown in the figures.
  • space-related terms are intended to encompass different orientations of the device in use or operation.
  • a device may be oriented in other ways (rotated 90 degrees or at other orientations), and the space-related descriptors used herein may also be used for explanation accordingly. It should be understood that when a component is “connected” or “coupled” to another component, the component may be directly connected to or coupled to another component, or an intermediate component may exist.
