  • Publication number: 20230200245
    Abstract: A chamber of a hybrid chemical and physical vapor deposition (HybCPVD) provides high-quality and uniform films on relatively large multiple wafers per growth run at reasonably high deposition rates using a scalable high-throughput process. Transition-metal-alloyed III-N single-crystalline and textured thin films are epitaxially and non-epitaxially deposited on a suitable substrate (of, for example, silicon or a metal such as aluminum or titanium) by providing a mixture of various gases in a deposition/growth chamber. The precursors for the chemical reactions include vapor phase of elements of transition metals, vapor phase of chlorides, and vapor phase of hydride. This growth technique provides high growth rate and high-quality epitaxial materials.

  • Patent number: 7985295
    Abstract: An RF heating system for a substrate or substrates including a susceptor for supporting the substrate; one or more RF heating coils; and a platen disposed between the RF heating coil and the substrate. The platen is constructed of materials that become heated under RF energy, which will then radiate heat into the susceptor and the substrate. In this way the susceptor need not be constructed of materials that become heated under RF energy thus minimizing levitation. The platen provides a uniform temperature profile across the substrates, benefiting from a more diffused heat source. The RF heating system may also be utilized in CVD apparatus that deposits materials on a continuous tape or roll.

  • Patent number: 6783745
    Abstract: A new class of carbon materials and their synthesis. The new carbon materials are formed by high pressure and high temperature processing of fullerene based carbon powder. The new carbon materials are harder than graphite and can be harder than steel (what the starting fullerenes are single wall nanotubes) or almost as hard as diamond (when the starting fullerened arm C60 buckyballs). The physical attributes of the materials can also be controlled by the pressing and heating parameters. These new carbon materials are conductive like graphite and unlike diamond which is an insulator. The materials can be formed by powder metallurgy techniques into any shape (cylinders, balls, tubes, rods, cones, foils, fibers or others). The new materials can also be readily doped, converted to diamond, formed within a porous composite or converted to diamond within the porous composite.

  • Publication number: 20040051126
    Abstract: Compositionally engineered CeXMnYO3 (Cerium Manganate) and electronic devices based thereon When the proportion of cerium to manganese in CeXMnYO3 is altered, a number of the electrical properties of the material are affected, among them are the ferroelectric and dielectric constant. By adjusting the proportion of cerium to manganese the deposited material can be either dielectric or ferroelectric. A silicon based transistor having a gate of ferroelectric CeXMnYO3 forms a single transistor non volatile memory cell, which does not require additional layers and thus greatly reduces architecture complexity and utilizes the standard operating voltage of a DRAM. A silicon based device having a capacitor, inductor or resistor made of dielectric CeXMnYO3 forms a passive structure which does not require additional layers and thus greatly reduce architecture complexity.

  • Patent number: 6702934
    Abstract: Deposition of thin films or powders by reactive pulsed arc molecular beam deposition. To produce these films and powders, a reactive or non-reactive gas is pulsed between a pair of electrodes situated within a vacuum chamber. The gas can be either chemically inert, to produce pure cathode material films, or chemically reactive, to produce chemical compounds of the cathode material. A storage capacitor is discharged between the electrode pair during the gas pulse. The gas serves as a carrier to direct and transport the ablated material to a substrate which is placed inline with the gas pulse, on which a film or powder of the electrode material or a chemical compound of the electrode material is then coated.

  • Patent number: 5544618
    Abstract: An apparatus for depositing a coating on a substrate substantially eliminates the occurrence of oval defects by creating a heated tortuous path through which the source material vapors must travel before depositing on the substrate. In addition, shut-off valves for each of the source materials are positioned in the reaction chamber in close proximity to the substrate, thereby enabling layers of different compositions to be deposited with sharp transitions between adjacent layers. The apparatus may be used to efficiently coat large areas uniformly, and works equally well with either elemental or chemical source materials, or certain combinations of both. The features of the coating apparatus may be embodied in replacement source cells for retrofitting in conventional molecular beam and chemical beam epitaxy units.
