Metal sulfide filled carbon nanotubes and synthesis methods thereof
Filled carbon nanotubes (CNTs) and methods of synthesizing the same are provided. An in situ chemical vapor deposition technique can be used to synthesize CNTs filled with metal sulfide nanowires. The CNTs can be completely and continuously filled with the metal sulfide fillers up to several micrometers in length. The filled CNTs can be easily collected from the substrates used for synthesis using a simple ultrasonication method.
Silicon coating on hard shields
A device including a hard shield material; a layer including aluminum or copper; and a silicon layer having a first thickness is disclosed. The device can also include a silicon layer having a second thickness. A method of making the device is also disclosed.
REDUCING LINE BENDING DURING METAL FILL PROCESS
Methods of mitigating line bending during feature fill include deposition of an amorphous layer and/or an inhibition treatment during fill.
Simultaneous selective deposition of two different materials on two different surfaces
In some embodiments, methods are provided for simultaneously and selectively depositing a first material on a first surface of a substrate and a second, different material on a second, different surface of the same substrate using the same reaction chemistries. For example, a first material may be selectively deposited on a metal surface while a second material is simultaneously and selectively deposited on an adjacent dielectric surface. The first material and the second material have different material properties, such as different etch rates.
METHOD FOR FORMING GRAPHENE BARRIER LAYER FOR SEMICONDUCTOR DEVICE AND CONTACT STRUCTURE FORMED BY THE SAME
Various embodiments generally relate to a method for forming a graphene barrier layer for a semiconductor device, and more particularly, to a method of forming a barrier thin film including a graphene layer capable of reducing the contact resistance of a metal interconnect.

METHOD FOR DECORATING A SUBSTRATE
A method for decorating a substrate which includes the succession of the following steps: provide the substrate; deposit a layer of a sacrificial material over a surface of the substrate; structure the sacrificial material layer so as to create in this sacrificial material layer a plurality of cavities to form a decorative or technical pattern; eliminate the sacrificial material layer except at the location where the pattern is provided.
Method for openly and continuously growing carbon nanomaterials
The invention discloses equipment and preparation method for open and continuous growth of a carbon nanomaterial. The equipment comprises a metal foil tape feeding system, a CVD system and a collection system. The method includes continuously conveying a metal foil tape pretreated or not into the CVD system via the metal foil tape feeding system, depositing a required carbon nanomaterial on the surface of the metal foil tape by CVD, directly collecting by the collection system or directly post-treating the carbon nanomaterial by a post-treatment system, and even directly producing a end product of the carbon nanomaterial. All the systems in the invention are arranged in the open atmosphere rather than an air-isolated closed space. The invention can realize round-the-clock continuous operation to greatly improve the production efficiency of carbon nanomaterials.

Air data probe corrosion protection
A method can include vapor depositing a corrosion resistant coating to internal and external surfaces of a metallic air data probe. For example, vapor depositing can include using atomic layer deposition (ALD). The method can include placing the metallic air data probe in a vacuum chamber and evacuating the vacuum chamber before using vapor deposition. The corrosion resistant coating can be or include a ceramic coating. In certain embodiments, vapor depositing can include applying a first precursor, then applying a second precursor to the first precursor to form the ceramic coating.
