A doped diamond semiconductor and method of production using a laser is disclosed herein. As disclosed, a dopant and/or a diamond or sapphire seed material may be added to a graphite based ablative layer positioned below a confinement layer, the ablative layer also being graphite based and positioned above a backing layer, to promote formation of diamond particles having desirable semiconductor properties via the action of a laser beam upon the ablative layer. Dopants may be incorporated into the process to activate the reaction sought to produce a material useful in production of a doped semiconductor or a doped conductor suitable for the purpose of modulating the electrical, thermal or quantum properties of the material produced. As disclosed, the diamond particles formed by either the machine or method of confined pulsed laser deposition disclosed may be arranged as semiconductors, electrical components, thermal components, quantum components and/or integrated circuits.

A method for processing a substrate in a plasma chamber is provided. The method includes providing a substrate on which an underlying layer to be etched and a mask are formed. The method further includes forming a protective film on the mask. The method further includes performing an anisotropic deposition to selectively form a deposition layer on a top portion of the mask.

Materials and methods for modifying semiconducting substrate surfaces in order to dramatically change surface energy are provided. Preferred materials include perfluorocarbon molecules or polymers with various functional groups. The functional groups (carboxylic acids, hydroxyls, epoxies, aldehydes, and/or thiols) attach materials to the substrate surface by physical adsorption or chemical bonding, while the perfluorocarbon components contribute to low surface energy. Utilization of the disclosed materials and methods allows rapid transformation of surface properties from hydrophilic to hydrophobic (water contact angle 120° and PGMEA contact angle) 70°. Selective liquiphobic modifications of copper over Si/SiOx, TiOx over Si/SiOx, and SiN over SiOx are also demonstrated.

A method of manufacturing a semiconductor device includes forming a protective layer over a substrate. The hydrophilicity of the protective layer is reduced. A resist layer is formed over the protective layer, and the resist layer is patterned.

Methods and techniques for deposition of amorphous carbon films on a substrate are provided. In one example, the method includes depositing an amorphous carbon film on an underlayer positioned on a susceptor in a first processing region. The method further includes implanting a dopant or the inert species into the amorphous carbon film in a second processing region. The implant species, energy, dose & temperature in some combination may be used to enhance the hardmask hardness. The method further includes patterning the doped amorphous carbon film. The method further includes etching the underlayer.

Disclosed are methods for providing a thin film of nanocrystalline diamond grown on 6 nm nanocrystalline diamond powder on the surface of substrates. The thin film of nanocrystalline diamond can be deposited on wide-bandgap semiconducting devices to provide heat dissipation characteristics to the semiconducting devices.

Embodiments of the present disclosure generally relate a process chamber including a lid and a chamber body coupled to the lid. The chamber body and lid define a process volume and a coupling ring is disposed within the chamber body and below the lid. The coupling ring is coupled to ground or is coupled to a coupling RF power source. A substrate support is disposed and movable within the process volume.

Exemplary semiconductor processing methods may include providing a carbon-containing precursor to a processing region of a semiconductor processing chamber. A substrate may be disposed within the processing region of the semiconductor processing chamber. The substrate may include a low dielectric constant material defining one or more features, a liner extending across the low dielectric constant material and within the one or more features, and a metal-containing layer deposited on the liner and extending within the one or more features. The methods may include forming a layer of material on at least a portion of the liner and the metal-containing layer. The layer of material may include graphene. The methods may include removing substantially all of the portion of the layer of material on the liner.

A multilayer diamond system includes an optically transparent substrate and an optically transparent intermediate layer deposited on the optically transparent substrate. A diamond layer is deposited on the optically transparent intermediate layer and formed from diamond having at least 50% of diamond grains sized between 2 nm and 500 nanometers.
