Abstract: The embodiments provide a structure and a method of manufacturing a semiconductor structure that has a different material in the area where PMOS devices will be formed than in the area where NMOS devices will be formed which is characterized as follows. An embodiment comprises the following steps. A substrate is provided. The substrate has a NMOS area and a PMOS area. We form a NMOS mask over the NMOS area. We form a first semiconductor layer over the PMOS area. We remove the mask. We form a second semiconductor layer over the NMOS area. Then we form an isolation region in the substrate between at least portions of the NMOS and the PMOS areas. We form PMOS devices in the PMOS area and form NMOS devices in the NMOS area.

Abstract: The invention describes a novel test structure and process to create the structure for performing automatic dynamic stress testing of PMOS devices for Negative Bias Temperature Instability (NBTI). The invention consists of an integrated inverter, two integrated electronic switches for switching from stress mode to device DC characterization measurement mode, and a PMOS FET device under test (DUT). The inverter assures the proper 180 degree phase relationship between the test device source and gate voltage while the imbedded electronic switches provide isolation of the test device during DC characterization testing. Another embodiment of the invention enables the testing of multiple devices under test (DUT's).

Abstract: An improved and new process of fabricating high dielectric constant MIM capacitors. These high dielectric constant MIM capacitor met all of the stringent requirements needed for both for both RF and analog circuit applications. For the high dielectric constant MIM capacitor, the metal is comprised of copper electrodes in a dual damascene process. The dielectric constant versus the total thickness of super lattices is controlled by the number of layers either 4/4, 2/2, and 1/1 artificial layers. Hence thickness of the film can be easily controlled. Enhancement of dielectric constant is because of interface. Dielectric constants near 900 can be easily achieved for 250 Angstrom thick super lattices.

Abstract: A method of fabricating first and second gates comprising the following steps. A substrate having a gate dielectric layer formed thereover is provided. The substrate having a first gate region and a second gate region. A thin first gate layer is formed over the gate dielectric layer. The thin first gate layer within the second gate region is masked to expose a portion of the thin first gate layer within the first gate region. The exposed portion of the thin first gate layer is converted to a thin third gate layer portion. A second gate layer is formed over the thin first and third gate layer portions. The second gate layer and the first and third gate layer portions are patterned to form a first gate within first gate region and a second gate within second gate region.
