Abstract: A method of treating structures (and the structure formed thereby), so as to prevent or retard the oxidation of a metal film, and/or prevent its delamination a substrate, includes providing a structure including a refractory metal film formed on a substrate, placing the structure into a vessel having a base pressure below approximately 10−7 torr, exposing the structure to a silane gas at a sufficiently high predetermined temperature and predetermined pressure to cause formation of a metal silicide layer on the refractory metal film, and exposing the structure to a second gas at a sufficiently high temperature and pressure to nitride the metal silicide layer into a nitrided layer.

Abstract: A buffer-layer to minimize the size of defects on a reticle substrate prior to deposition of a reflective coating on the substrate. The buffer-layer is formed by either a multilayer deposited on the substrate or by a plurality of sequentially deposited and annealed coatings deposited on the substrate. The plurality of sequentially deposited and annealed coating may comprise multilayer and single layer coatings. The multilayer deposited and annealed buffer layer coatings may be of the same or different material than the reflecting coating thereafter deposited on the buffer-layer.

Abstract: A method and apparatus, and product by process, for the production of bulk polysilicon by broad area chemical vapor deposition, consisting of a quartz envelope and base plate forming a reactor enclosure, with external radiant heaters providing the heat source. A thin wall, edge-defined film fed growth (EFG) silicon tube section is used as the deposition casing and reaction chamber wall. The tube is capped at the top and sealed to the base plate to form the reaction chamber. External heaters radiate heat through the quartz enclosure to heat the tube wall to deposition temperature. A through flow of process gas is introduced to initiate the deposition. A uniform wide surface area deposit occurs on the inside surface of the tube, causing the diameter to become increasingly smaller as the yield accumulates.

Abstract: A titanium layer is formed on a substrate with chemical vapor deposition (CVD). First, a seed layer is formed on the substrate by combining a first precursor with a reducing agent by CVD. Then, the titanium layer is formed on the substrate by combining a second precursor with the seed layer by CVD. The titanium layer is used to form contacts to active areas of substrate and for the formation of interlevel vias.

Abstract: In a vacuum processing apparatus comprising a reactor and a vacuum pump connected to the reactor to draw up a gas held in the reactor, the vacuum pump comprising a diffusion pump and an auxiliary pump, the diffusion pump and the auxiliary pump are connected through an exhaust line and a cooling unit is provided in the exhaust line, where the gas is cooled by the cooling unit to liquefy or condense an oil smoke comprised of a diffusion pump oil contained in the gas, to cause the resultant oil to deposit in the exhaust line.
Abstract: A method of depositing a silicon oxide coating on hot glass at a temperature below 600° C. comprising contacting the hot glass with a gaseous mixture of a source of silicon and oxygen enriched with ozone. Preferably, the hot glass in the form of a hot glass ribbon is contacted with the gaseous mixture during the float glass production process downstream of the float bath. Preferred sources of silicon are silanes, alkylsilanes, alkoxysilanes and siloxanes.

Abstract: An ozone-processing apparatus for a semiconductor process system includes an airtight process chamber and a lamp chamber, which are partitioned by a window for transmitting ultraviolet rays. A plurality of ultraviolet-ray lamps is arrayed along the window in the lamp chamber. A measurement space is defined between the window and the lamps in the lamp chamber. The lamp chamber is provided with a mount portion to set up a measuring unit therein. The measuring unit includes a sensor to be inserted into the measuring space, for measuring the light quantity of the lamps. The sensor is movable in a direction in which the lamps are arrayed.
Abstract: A method and an apparatus for increasing a deposition rate of dielectric films deposited on a substrate for a given temperature while providing the same with good step coverage and gap-fill properties. This is achieved by employing bistertiarybutylaminesilane as a silicon source to react with an oxidizing agent to form a dielectric film on a substrate that includes silicon.
Abstract: An apparatus and a method for oxidizing silicon substrates by either a wet oxidation or a dry oxidation process in the same oxidation chamber are provided. In the apparatus, an additional conduit is provided for evacuating any residual water vapor trapped in a conduit section between an external torch and the oxidation chamber such that residual water vapor does not flow into the oxidation chamber and cause problems for a dry oxidation process subsequently conducted. The present invention novel apparatus therefore allows thin silicon oxide films such as those used in gate oxides to be formed with high quality in the same oxidation chamber. The present invention novel apparatus further allows high quality tri-layered silicon oxide films to be formed in a dry-wet-dry oxidation process for achieving satisfactory deposition rates and high quality oxide films on the substrate.
Abstract: An electrostatic actuator comprising opposing electrode members displaced relatively by an electrostatic force is provided with improved durability so that electrostatic attraction between opposing members does not drop and the opposing electrode members do not stick together. Hydrophobic films of hexamethyldisilazane (HMDS) are formed on a surface of segment electrode and a bottom surface of a diaphragm (common electrode) of an eletrostatic actuator wherein the diaphragm forms a wall of an ink chamber in an ink jet head. HMDS molecules are smaller than PFDA molecules, and a uniform, variation-free hydrophobic film can therefore be formed even when the gap between opposing electrodes is narrow. Durability and film stability of a HMDS hydrophobic film are also high. An electrostatic actuator with high durability and operating stability can thus be achieved.
Abstract: A silicon article including a silicon base and columns extending from the silicon base. The columns define a gap between the columns which is devoid of material so that the article can act as a filter or heat sink. Also disclosed is a method of making the silicon article.
