Abstract:
1. A process of forming an electronic device comprising: forming a gate electrode layer over a substrate, wherein forming the gate electrode layer includes: forming a patterned masking layer including a masking member and an opening, wherein: removing an upper portion of the gate electrode layer to form a lower portion of the gate electrode layer overlying the second region of the substrate that includes the first electrode layer and a remaining portion of the second electrode layer, wherein the lower portion of the gate electrode layer has a third thickness greater than the first thickness; performing a process operation other than removing substantially all of the lower portion of the gate electrode layer; and removing substantially all of the lower portion of the gate electrode layer overlying the second region of the substrate to form a gate electrode overlying the first region of the substrate, wherein removing substantially all of the lower portion of the gate electrode layer is performed after performing the process operation.
