Abstract
In one implementation, a method for fabricating a tiered structure is provided, which includes forming a source and a drain on a substrate with a gate formed therebetween. Formation of the gate includes depositing a gate foot using a gate foot mask having an opening through it to define the gate foot over the substrate. After forming the gate foot, the gate foot mask is stripped. A gate head mask is formed over the gate foot with the gate head mask exposing a top portion of the gate foot. A gate head is formed on the top portion of the gate foot using the gate head mask. A lift-off process is performed, removing the gate head mask.
