Abstract

Methods of forming transistor devices and structures thereof are disclosed. A first dielectric material is formed over a workpiece, and a second dielectric material is formed over the first dielectric material. The workpiece is annealed, causing a portion of the second dielectric material to combine with the first dielectric material and form a third dielectric material. The second dielectric material is removed, and a gate material is formed over the third dielectric material. The gate material and the third dielectric material are patterned to form at least one transistor.
