An electronic device having a substrate structure having an undercut region is provided and further included is a method for forming an undercut region of a substrate structure. The method includes identifying a plurality of sets of substantially identical adjacent pixels within the frame and determining a number of pixels in each set. The translatable structure includes a rearward region partly defining a diverging nozzle region. The air fuel ratio sensor disposed upstream of the catalyst converter. The method comprises removing a first dielectric component from a fluid distribution element of the electrostatic chuck and replacing the first dielectric component with a second dielectric component. The upper and lower mold bodies have respective upper and lower mold surfaces for contacting the fibrous molding media positioned within the mold, and have gas flow openings configured to direct gases into contact with the fibrous molding media.
