Abstract

An apparatus having an active device, a plurality of traces and one or more areas is disclosed. The active device may have a channel layer. A buffer layer is generally disposed between the channel layer and a substrate. A parasitic layer may be formed at an interface between the buffer layer and the substrate. The traces may be connected to the active device. The areas are generally proximate at least one of (i) the active device and (ii) at least two of the traces from which the parasitic layer is removed.
