    • PURPOSE:To eliminate bad influence of a gas released from a substrate on vacuum condition of a ultra-high vacuum chamber, by releasing the gas from the substrate in a substrate feed chamber, and sending the substrate to a growing chamber. CONSTITUTION:The gate valve 20 is closed, and the substrate feed chamber 30 is opened to atmospheric pressure in a state where the growing chamber 10 is kept in an ultra-high vacuum state. In this state, the cassette having the substrate 50 is sent to the substrate feed chamber 30, and the cassette 40 is placed on the cassette receiving stand 61 of the cassette lift 60. Then, the sub strate feed chamber 30 is hermetically sealed, and evacuated by operation of a high vacuum exhaust device. Then, electricity is applied to the heater 81 by the electric source 83, heat is generated by the heater 81, the heat equalizing plate 82 is heated, the substrate 50 put in the cassette 40 is uniformly heated by its radiation, and a gas in the substrate is released. The substrate 50 from which the gas is released is taken out from the cassette 40 by the manipulator 70, sent from the substrate feed chamber 30 through the gate valve 20 to the growing chamber 10 to grow crystal on the substrate and to make a film.
    • 目的:为了消除从基板释放的气体对超高真空室的真空状况的不良影响,通过在基板供给室中从基板释放气体,并将基板送至生长室。 构成:在生长室10保持在超高真空状态的状态下,关闭闸阀20,将基板供给室30打开至大气压。 在该状态下,将具有基板50的盒子送到基板供给室30,将盒40放置在盒式升降机60的盒式收纳台61上。然后,将底板进料室30气密地密封, 通过高真空排气装置的操作抽真空。 然后,通过电源83对加热器81施加电力,加热器81产生热量,加热均热板82,放入盒40中的基板50被其辐射均匀地加热, 衬底被释放。 通过操作器70从盒40中取出气体被释放的基板50,从基板供给室30通过闸阀20送到生长室10,在基板上生长晶体并制成膜。

    • PURPOSE:To make a space factor best, to reduce and occupied floor area of the apparatus, and to improve the throughput, by constituting a plural of crystal-growing chambers so that planes passing through the respective chambers have respective phase differences to the vertical direction. CONSTITUTION:The present apparatus is comprised of an inserting chamber 1, a preliminary chamber 2, a carrying chamber 3, six crystal-growing chambers 4-9, and a taking-out chamber 10, each chamber being connected with each vacuum exhausting system corresponding to each application. Substrates can be selectively transferred into the plural of crystal-growing chambers from a linking positon in the carrying chamber, and there exists no dead space. Moreover, crystal-growing chambers are mounted at multi-levels, with being out of phase one another, so that the crystal-growing chambers for respective exclusive uses, for example a Ga and As growing chamber, a Fa, As and Al growing chamber, an In and P growing chamber, etc., are employed, preventing the molecule beam sources from being contaminated when they are not used.
    • 目的:通过构成多个晶体生长室,使通过各个室的面相对于垂直方向具有相位差,为了减小和占用设备的占地面积并提高通过量,使空间因子最佳 。 构成:本装置包括插入室1,预备室2,搬运室3,六个晶体生长室4-9和取出室10,每个室与每个真空排气系统相对应 到每个应用程序。 衬底可以从承载室中的连接位置选择性地转移到多个晶体生长室中,并且不存在死空间。 此外,晶体生长室以多层安装,彼此异相,使得用于各种专用的晶体生长室,例如Ga和As生长室,Fa,As和Al生长室 ,In和P生长室等,防止分子束源在不使用时受到污染。

    • PURPOSE:To form a diamond thin film having excellent adhesivity to the substrate and high density and hardness, by evaporating carbon from a carbon- containing evaporation source to a substrate, and irradiating the substrate with accelerated ion seed simultaneously or alternately to the evaporation. CONSTITUTION:A substrate 7 made of ceramics, carbide alloy, thermet, various metals and alloys, etc. is attached to a holder 8 and placed in a reaction chamber 5 connected with a vacuum pump 6. An evaporation source such as amorphous carbon, graphite, diamond, etc. is heated with an evaporation apparatus 10 using an electron beam, etc. to evaporate the carbon to said substrate 7. On the other hand, N2 etc. is supplied through a leak valve 1, ionized to N ion by the ion source 2, passed through the accelerator 3, the analyzing magnet 4, and the ion accumulation lens 9, and radiated to the evaporation layer simultaneously or alternately to the evaporation process. A diamond carbon and/or a diamond thin film is formed on the substrate by this process. A thin film having the highest characteristics can be produced when the ratio of th atomic number of the evaporated atom to the charge number of the ion is 0.1-5 and the acceleration energy of the ion is 6-60keV per atom.
