摘要:
A method and system for modifying a gate dielectric stack by exposure to a plasma. The method includes providing the gate dielectric stack having a high-k layer formed on a substrate, generating a plasma from a process gas containing an inert gas and one of an oxygen-containing gas or a nitrogen-containing gas, where the process gas pressure is selected to control the amount of neutral radicals relative to the amount of ionic radicals in the plasma, and modifying the gate dielectric stack by exposing the stack to the plasma.

The present invention provides method of forming a gate dielectric that includes forming a metal source layer (210) comprising a metal and at least one nonmetallic element over a substrate (110). The metal source layer (210) is formed having a composition rich in the metal. A dielectric layer (310) comprising the metal is formed over the metal source layer (210).
摘要:
An integrated circuit having a gate dielectric layer (414, 614, 814) having an improved nitrogen profile and a method of fabrication. The gate dielectric layer is a graded layer with a significantly higher nitrogen concentration at the electrode surface than near the substrate surface. An amorphous silicon layer (406) may be deposited prior to nitridation to retain the nitrogen concentration at the top surface (416). Alternatively, a thin silicon nitride layer (610) may be deposited after anneal or a wet nitridation process may be performed.

A pull down bed with automatic locking device has a movable framework, which constitutes a mattress frame, and is hinged to a container body, which constitutes a piece of furniture, so as to define a closed position, in which said mattress frame is substantially inside the piece of furniture, and an open position, for use as a bed, in which the mattress frame is in a horizontal position and rests on the ground by means of two feet. The mattress frame is hinged to the piece of furniture at one end and has its feet at the other end. The pull down bed includes a device for locking said mattress frame in the closed or horizontal position, which is actuated by an actuation device, which includes the feet.

The invention provides methods and compositions for treatment of bacterial infections. The composition may be a combination of factors, which include A0, A1, B1, B2, C0, C1, isoB0, and MAG, in the presence of low level solvent. Methods of the invention include administration of dalbavancin formulations for treatment of a bacterial infection, in particular a Gram-positive bacterial infection of skin and soft tissue. Dosing regimens include multiple dose administration of dalbavancin, which often remains at therapeutic levels in the bloodstream for at least one week, providing prolonged therapeutic action against a bacterial infection. Dosing regimens for renal patients are also included.
摘要:
A process of sorting metallic single wall carbon nanotubes (SWNTs) from semiconducting types by disposing the SWNTs in a dilute fluid, exposing the SWNTs to a dipole-inducing magnetic field which induces magnetic dipoles in the SWNTs so that a strength of a dipole depends on a conductivity of the SWNT containing the dipole, orienting the metallic SWNTs, and exposing the SWNTs to a magnetic field with a spatial gradient so that the oriented metallic SWNTs drift in the magnetic field gradient and thereby becomes spatially separated from the semiconducting SWNTs. An apparatus for the process of sorting SWNTs is disclosed.
摘要:
Concurrently forming different metal gate transistors having respective work functions is disclosed. In one example, a metal carbide, which has a relatively low work function, is formed over a semiconductor substrate. Oxygen and/or nitrogen are then added to the metal carbide in a second region to establish a second work function in the second region, where the metal carbide itself establishes a first work function in a first region. One or more first metal gate transistor types are then formed in the first region and one or more second metal gate transistor types are formed in the second region.
