Abstract: The present disclosure relates to an integrated circuit (IC) and a method of formation. In some embodiments, a first transistor gate stack is disposed in a low voltage region defined on a substrate. The first transistor gate stack comprises a first gate electrode and a first gate dielectric separating the first gate electrode from the substrate. A third transistor gate stack is disposed in a high voltage region defined on the substrate. The third transistor gate stack comprises a third gate electrode and a third gate dielectric separating the third gate electrode from the substrate. The third gate dielectric comprises an oxide component and a first interlayer dielectric layer.

Abstract: In some embodiments, a semiconductor device is provided. The semiconductor device includes a pair of source/drain regions disposed in a semiconductor substrate, where the source/drain regions are laterally spaced. A gate electrode is disposed over the semiconductor substrate between the source/drain regions. Sidewall spacers are disposed over the semiconductor substrate on opposite sides of the gate electrode. A silicide blocking structure is disposed over the sidewalls spacers, where respective sides of the source/drain regions facing the gate electrode are spaced apart from outer sides of the sidewall spacers and are substantially aligned with outer sidewalls of the silicide blocking structure.

Abstract: A semiconductor structure and a method for fabricating the same are provided. The semiconductor structure includes a wafer substrate having a top surface and a bottom surface, and a conductive pillar in the wafer substrate defined by a deep trench insulator through the top surface and the bottom surface of the wafer substrate. The method for fabricating the semiconductor structure includes following steps. A deep trench is formed from a top surface of a wafer substrate to define a conductive region in the wafer substrate. The conductive region is doped with a dopant. The deep trench is filled with an insulation material to form a deep trench insulator. And the wafer substrate is thinned from a bottom surface of the wafer substrate to expose the deep trench insulator and isolate the conductive region to form a conductive pillar.
