In one embodiment a transistor is formed with a gate structure having an opening in the gate structure. The multi-media device includes a first and second substrate coupled to each other. The innerbody has a beveled shoulder around a lower outer wall thereof. The demapping element can then be capable of estimating the amplitude of a signal constellation of the QAM signal over either one or more of the slot or fractions of the slot based upon the speed of the receiver. In addition, since the black matrix may exhibit superior electrical conductivity, it may be used in electromagnetic interference filters without additional front-surface blackening.
