摘要:
A metal film forming method comprises steps of: forming a non-monocrystalline metal film principally composed of aluminum, in contact, at least in a part thereof, with a monocrystalline metal principally composed of aluminum; and heating the non-monocrystalline metal film to convert at least a part thereof into monocrystalline state.
摘要:
A process for forming a deposition film comprising aluminum comprises the steps of: treating chemically a surface of a substrate having an electron-donative surface and a non-electron-donative surface so as to terminate the electron-donative surface with hydrogen atoms, and thereafter placing the substrate in a space for deposition film formation; introducing gas comprising alkylaluminum hydride and hydrogen gas into the space for deposition film formation; and forming an aluminum film selectively on the electron-donative surface by maintaining the substrate at a temperature in the range of from not lower than the decomposition temperature of the alkylaluminum hydride to not higher than 450°C.

An apparatus for vaporizing a liquid raw material (2) comprises a nozzle (4) with an open tip end for ejecting a liquid raw material into a heated gas (31) atmosphere as liquid droplets and a heated plate (30) with a small opening (40) disposed in front of the nozzle, a space opposite to that occupied by the nozzle with respect to the plate being evacuated.

A code division multiplex communications system comprises: receiving means (1,2) for receiving a radio wave and transforming the radio wave to an electric signal; voltage-current converting means (101) for converting the electric signal to a current signal; current delaying means (102, 102 2 ... 102 n ) for sequentially reading the electric signal at a timing of a clock pulse; adding and subtracting means (105) for adding and subtracting output currents of the current delaying means in accordance with a spread code; and reproducing means (107) for reproducing a transmission signal on the basis of an output of the adding and subtracting means.

A semiconductor circuit device wiring is provided in which the wiring connected to a semiconductor element is composed of a crystalline material. The crystal axis direction along which nearest neighboring atoms in a single crystal constituting the crystalline material are arranged and the electric current direction through the wiring are crossed with each other at an angle of 22.5° or less.
