A semiconductor structure includes raised source and drain regions, where the raised source and drain regions are facet free and unconstrained to have a shape conforming to a same crystallographic axes with respect to each other.

Described is a wet chemical surface treatment involving NH4OH that enables extremely strong direct bonding of two wafer such as semiconductors (e.g., Si) to insulators (e.g., SiO2) at low temperatures (less than or equal to 400° C.). Surface energies as high as ˜4835±675 mJ/m2 of the bonded interface have been achieved using some of these surface treatments. This value is comparable to the values reported for significantly higher processing temperatures (less than 1000° C.). Void free bonding interfaces with excellent yield and surface energies of ˜2500 mJ/m2 have also be achieved herein.

摘要:
The present invention relates to a method of reducing Si consumption during a self-aligned silicide process which employs a M—Si or M—Si—Ge alloy, where M is Co, Ni or CoNi and a blanket layer of Si. The present invention is particularly useful in minimizing Si consumption in shallow junction and thin silicon-on-insulator (SOI) electronic devices.

摘要:
A method (and resultant structure) for forming a metal silicide contact on a silicon-containing region having controlled consumption of said silicon-containing region, includes implanting Ge into the silicon-containing region, forming a blanket metal-silicon mixture layer over the silicon-containing region, reacting the metal-silicon mixture with silicon at a first temperature to form a metal silicon alloy, etching unreacted portions of the metal-silicon mixture layer, forming a blanket silicon layer over the metal silicon alloy layer, annealing at a second temperature to form an alloy of metal-Si2, and selectively etching the unreacted silicon layer.
