  • Publication number: 20030175426
    Abstract: In a method for processing a substrate, a plurality of substrates maintained in a boat are loaded into a cylindrical inner tube disposed in a cylindrical outer tube. A processing gas is supplied into a process room, and thereafter the substrates are batch-processed with the processing gas evacuated through an exhaust path formed between the inner tube and the outer tube, wherein nitrogen gas is supplied to a surface region of the ceiling of the outer tube during a film forming process of the substrates, thereby the processing gas ascended through the process room is prevented from coming into contact with the ceiling of the outer tube by the nitrogen gas covering thereat. Accordingly, products and/or by-products of the film forming gas is prevented from being adhered thereto, thereby formation of contaminants due to the deterioration of the deposition of the products and the by-products thereof can be eliminated/reduced.

  • Patent number: 6599574
    Abstract: The present invention relates to the deposition of dielectric layers, and more specifically to a method and apparatus for forming dielectric layers such as borophosphosilicate glass (BPSG) having improved film uniformity, higher deposition rate, superior gap fill/reflow capability, and smoother surface morphology. The method forms a dielectric layer with a process using helium carrier gas that produces substantially less downstream residue than conventional methods and apparatus, thereby reducing the need for chamber cleaning and increasing throughput of processed wafers. The present invention utilizes helium instead of nitrogen as carrier gas in a process for forming a dielectric layer such as BPSG to provide various unexpected benefits. According to one aspect, the present invention forms a dielectric film on a substrate, and prolongs a period between chamber cleanings in a system by using helium which produces substantially less downstream and upstream residue than a process using nitrogen.

  • Patent number: 6599636
    Abstract: A titanium aluminide substrate (4) is vulnerable to air oxidation, limiting the use of this substrate in a variety of industrial applications, including the aircraft and aerospace industries. A bilayer reactive barrier (2) is formed on a titanium aluminide substrate. The barrier layer includes an &agr;-Al2O3 layer (6) from the reaction of oxygen from the disassociation of water with alumina in a gaseous and water vapor atmosphere at high temperatures and low oxygen concentration. During the process, titanium migrates through the &agr;-Al2O3 to a gas/barrier layer surface (14) and is oxidized to form a Ti2O3 layer (8). A surface of the Ti2O3 layer is subsequently oxidized to form a TiO2 layer (12). In this manner, a triple layer barrier is formed in which the immersible TiO2 and &agr;-Al2O3 are separated by Ti2O3. The three layers are bonded to each with a bond strength greater than 4500 kPa.

  • Patent number: 6582777
    Abstract: A process for forming low dielectric constant dielectric films for the production of microelectronic devices. A dielectric layer is formed on a substrate by chemical vapor depositing a monomeric or oligomeric dielectric precursor in a chemical vapor deposit apparatus, or a reaction product formed from the precursor in the apparatus, onto a substrate, to form a layer on a surface of a substrate. After optionally heating the layer at a sufficient time and temperature to dry the layer, the layer is then exposed to electron beam radiation, for a sufficient time, temperature, electron beam energy and electron beam dose to modify the layer. The electron beam exposing step is conducted by overall exposing the dielectric layer with a wide, large beam of electron beam radiation from a large-area electron beam source.

    Abstract: An apparatus and method for depositing thin films on the surface of a device such as a spherical shaped devices. The apparatus includes an enclosure containing a plurality of apertures and a conductor coil. The apertures connect to conduits for inputting and outputting the devices as well as injecting and releasing different gases and/or processing constituents. A chamber is formed within the enclosure and is configured to be coaxial with the conductor coil. Devices move through the input conduit where they are preheated by a resistance-type furnace. The preheated devices then move into the chamber where chemical precursors are added and the devices are further heated to a predefined temperature associated with the chemical precursors by radio frequency energy from the conductor coil. At this time, the gases and/or processing constituents react with the heated device thereby growing a thin film on its outer surface.

  • Patent number: 6274194
    Abstract: The present invention relates to a surface treatment for hydrogen-absorbing alloy. More particularly, the present invention relates to a surface treatment for hydrogen-absorbing alloy by which the poisoning resistance of a surface of alloy powder with respect to oxide film, water or absorbing gas can be enhanced so that activation treatment can be easily conducted on alloy powder. In the method, the poisoning resistance is enhanced by forming a protective film, which contains at least one of sulfide and fluoride, on the surface of hydrogen-absorbing alloy powder in an atmosphere containing SF6 gas when hydrogen-absorbing alloy is crushed or hydrogen-absorbing alloy is in a state of powder or when hydrogen-absorbing alloy is made into powder by rapidly cooling and solidifying.

  • Publication number: 20010006701
    Abstract: A CVD apparatus for depositing a copper interconnect film on a substrate is equipped with a first CVD module 15 which deposits a copper film as a foundation using a Cu(hfac)(tmvs)-based precursor material having a small film deposition rate, and a second CVD module 16 which performs film deposition to increase the thickness of the copper film using a Cu(hfac)(atms)-based precursor material having a large film deposition rate. The film deposition rate of the Cu(hfac)(tmvs)-based precursor material is about 100 nm per minute and the film deposition rate of the Cu(hfac)(atms)-based precursor material is about 400 nm per minute. This realizes a practical CVD apparatus for mass production which achieves both a high film deposition efficiency and high film quality.

  • Patent number: 6239040
    Abstract: A method of coating an amorphous silicon layer. An amorphous silicon layer is directly deposited on the polysilicon nodes by a self-aligned method. A chemical mechanical polishing process is performed to control the thickness of the amorphous silicon layer. No additional photoresist is used during the whole processes. Therefore, the duration for deposition can be reduced and the quality of the amorphous silicon film is improved.

  • Patent number: 6180190
    Abstract: An apparatus is used to turn liquids into vapors for use in chemical vapor deposition. It uses a high-frequency ultrasonic plate to break the liquid into tiny droplets and a gas-dynamic sorting tower to reprocess larger droplets into smaller ones before quickly vaporizing them. The method can vaporize liquids with high efficiency even if they have low vapor pressures and limited thermal stability. The vapor concentration can be set to a known and reproducible value by setting the pumping rate. The apparatus can rapidly start and stop the vapor flow. The pressure drop in the carrier gas is very small. Only a very small dead volume of liquid is contained in the apparatus at any given time, so little is wasted when the system is cleaned.

  • Patent number: 6169023
    Abstract: An SiOF layer is formed by using as raw material an organic Si compound having Si—F bonds. Since an organic Si compound is used as raw material, an intermediate product being formed during the formation of an SiOF layer is liable to polymerize and has fluidity. Moreover, since the organic Si compound has Si—F bonds, low in bond energy, and is thus capable of easily getting only Si—F bonds separated, the SiOF layer is prevented from getting contaminated by reaction by-products and fluorine can be introduced into the SiOF layer in stable fashion. Therefore, an insulator layer, low in dielectric constant, low in hygroscopicity and excellent in step coverage, can be formed by using a low powered apparatus.
