To understand the growth mechanism and the effect of catalysts in growing III–V epitaxial nanowires, GaAs (111)B substrates with Au thin films were annealed in a molecular beam epitaxy (MBE) system. Scanning/transmission electron microscopy (SEM/TEM) investigations indicate that, during annealing, the Au catalysts were formed and affect significantly the surface morphology of the GaAs substrates.
For the first time, Ge CMOS with all thermal processes performed by microwave annealing (MWA) has been realized. The full MWA process is under 390 oC. It significantly outperforms conventional rapid thermal annealing (RTA) process in 3 aspects: (1) Diffusion-less junction: for easily diffused n-type dopant, phosphorous (P), the ion implantation dopant profile after the MWA activation process remains...
In this paper, we have demonstrated that cryogenic implantation applied to source and drain (SD) extension, pocket/halo and SD formation offers advantages for higher core and SRAM driving current and one order lower Ioff bulk (Ioffb) leakage in NMOS with reduced SRAM defectivity. Atomistic Kinetic Monte Carlo (KMC) modeling confirms that the cryo-implantation has enabled a unique control of active...
Strain techniques have been adopted and widely used in the advanced nodes since early 65nm for carrier mobility improvement. For PMOS, eSiGe incorporation in the SD is the process of choice to induce compressive strain in the channel for mobility improvement. To further lower the contact resistance, it is preferred to boost Boron concentration for pSD formed by eSiGe process. Normal implant process...
