摘要： The present invention provides a gate stack structure that has high mobilites and low interfacial charges as well as semiconductor devices, i.e., metal oxide semiconductor field effect transistors (MOSFETs) that include the same. In the semiconductor devices, the gate stack structure of the present invention is located between the substrate and an overlaying gate conductor. The present invention also provides a method of fabricating the inventive gate stack structure in which a high temperature annealing process (on the order of about 800° C.) is employed. The high temperature anneal used in the present invention provides a gate stack structure that has an interface state density, as measured by charge pumping, of about 8×1010 charges/cm2 or less, a peak mobility of about 250 cm2/V-s or greater and substantially no mobility degradation at about 6.0×1012 inversion charges/cm2 or greater.

摘要： Silicidation techniques with improved rare earth silicide morphology for fabrication of semiconductor device contacts. For example, a method for forming silicide includes implanting a silicon layer with an amorphizing species to form an amorphous silicon region in the silicon layer and depositing a rare earth metal film on the silicon layer in contact with the amorphous silicon region. A suicide process is then performed to combine the rare earth metal film and the amorphous silicon region to form a silicide film on the silicon layer.

摘要： A lateral heterojunction bipolar transistor is formed on a semiconductor-on-insulator substrate including a top semiconductor portion of a first semiconductor material having a first band gap and a doping of a first conductivity type. A stack of an extrinsic base and a base cap is formed such that the stack straddles over the top semiconductor portion. A dielectric spacer is formed around the stack. Ion implantation of dopants of a second conductivity type is performed to dope regions of the top semiconductor portion that are not masked by the stack and the dielectric spacer, thereby forming an emitter region and a collector region. A second semiconductor material having a second band gap greater than the first band gap and having a doping of the second conductivity type is selectively deposited on the emitter region and the collector region to form an emitter contact region and a collector contact region, respectively.
