    Abstract: A method of forming a gate structure over a hybrid substrate structure with topography having a bulk region and an SOI region is disclosed including forming a gate material layer above the SOI and bulk regions, forming a mask layer above the gate material layer, forming a first planarization layer above the mask layer, forming a first gate structure masking pattern above the first planarization layer, patterning the first planarization layer in alignment with the first gate structure masking pattern, and patterning the mask layer in accordance with the patterned first planarization layer, resulting in a gate mask disposed above the gate material layer.
