Abstract:
A method of making a microelectronic device comprising the steps of:providing a substrate; forming an input signal line over the substrate; forming an output signal line over the substrate and spaced apart from the input signal line; forming a first sacrificial layer over the input signal line and the output signal line; removing a portion of the first sacrificial layer over the input signal line to form a first opening and over the output signal line to form a second opening; forming a second sacrificial layer over the first sacrificial layer, the first opening, and the second opening, wherein a first recess and a second recess are formed over the first opening and the second opening; and forming a conductive layer over a portion of the second sacrificial layer, the first recess, and the second recess, wherein the step of forming the second sacrificial layer comprises forming a second polyimide layer.
