摘要： Crystalline carbon-based thin film structures are formed in which a compositionally-graded intermediate layer is first deposited on a substrate, and a crystalline carbon-based thin film such as silicon carbide or diamond is deposited thereafter on the intermediate layer. The compositionally-graded intermediate layer has a carbon content which increases in a direction away from the substrate. The compositionally-graded intermediate layer is effective in reducing problems associated with the lattice mismatch between the thin film and the substrate which hamper conventional hetero-epitaxial growth of high quality crystalline carbon-based thin films.

摘要： A method of producing an amorphous silicon semiconductor device makes use of a capacitance-coupled high-frequency glow-discharge semiconductor production apparatus which is equipped with a plurality of glow-discharge chambers each having a high-frequency electrode and a substrate holder opposing each other and means for supplying material gases to the glow-discharge chambers. A reaction of a material gas is effected in a first glow-discharge chamber, so as to form a semiconductor layer having a first conductivity type on a substrate introduced into the first glow-discharge chamber, and, after moving the substrate into a second glow-discharge chamber, a reaction of a material gas different from the material gas used in the first glow-discharge chamber is effected, thereby forming a semiconductor layer having a second conductivity type on the semiconductor layer of the first conductivity type. The substrate with the semiconductor layer of the first conductivity formed thereon is moved from the first glow-discharge chamber to the second glow-discharge chamber after a predetermined gas atmosphere is formed in the first glow-discharge chamber. The distance between the electrode and the substrate holder is made smaller in one of the first and second glow-discharge chambers which is designed for forming the thicker one of the semiconductor layers of the first and second conductivity types than in the other of the first and second glow-discharge chambers. The temperature of the substrate is set higher in one of the first and second glow-discharge chambers which is designed for forming the thicker one of the semiconductor layers of the first and second conductivity types than in the other of the first and second glow-discharge chambers.

摘要： A large area semiconductor element can be manufactured with high productivity, which has low electric resistance at the boundary face of a metal and a semiconductor and has excellent characteristics and reliability. A manufacturing apparatus comprises an ion irradiation means for simultaneously irradiating hydrogen ions and ions containing an element serving as a dopant of a semiconductor to a semiconductor film or a substrate in an atmosphere under reduced pressure, and a film forming means which forms a thin film or a heat treatment means which conducts a heat treatment without exposing a sample to an air. When a sample having an a-Si:H thin film is brought into a sample preparation chamber by opening a gate valve, the chamber is exhausted to have the inside pressure of 10.sup.2 to 10.sup.-3 Pa. Then, the sample is forwarded to an ion irradiation chamber from the sample preparation chamber via an intermediate chamber of which the pressure is maintained in the range of 10.sup.-3 to 10.sup.-7 Pa, and ions such as phosphous are irradiated. After the ion irradiation, a gate valve is opened to transfer the sample to the intermediate chamber, and then a gate valve is opened to forward the sample to a deposition chamber. Subsequently, Ar gas is let in to the deposition chamber and a metal film of Al/Ti is deposited by a sputtering method. After the deposition, the sample is forwarded to a sample carry-out chamber via the intermediate chamber.
