In addition, terms such as "first", "second" and other numerical terms are used in this text, and do not imply order or sequence unless the text is explicitly indicated. Therefore, the above-discussed first element, component, area, layer or section can be referred to as the second element, component, area, layer or section without departing from the teachings of the example embodiments.

[0051] Spatially relative terms, such as "internal", "external", "lower", "under", "bottom", "top", "above", and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms can be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0052] In the above discussion, unless otherwise stated, the terms "about", "approximately", "substantially" and the like, when used in describing a numerical value, mean a variation of + / - 10% of the value.
