    • There are provided a method and an apparatus which form silicon dots having substantially uniform particle diameters and exhibiting a substantially uniform density distribution directly on a substrate at a low temperature. A hydrogen gas (or a hydrogen gas and a silane-containing gas) is supplied into a vacuum chamber (1) provided with a silicon sputter target (e.g., target 30), or the hydrogen gas and the silane-containing gas are supplied into the chamber (1) without arranging the silicon sputter target therein, a high-frequency power is applied to the gas(es) so that plasma is generated such that a ratio (Si(288 nm)/Hβ) between an emission intensity Si(288 nm) of silicon atoms at a wavelength of 288 nm and an emission intensity Hβ of hydrogen atoms at a wavelength of 484 nm in plasma emission is 10.0 or lower, and preferably 3.0 or lower, or 0.5 or lower, and silicon dots (SiD) having particle diameters of 20 nm or lower, or 10 nm or lower are formed directly on the substrate (S) at a low temperature of 500 deg. C. or lower in the plasma (and with chemical sputtering if a silicon sputter target is present).
    • 提供了形成具有基本上均匀的粒径并且在低温下直接在基底上表现出基本均匀的密度分布的硅点的方法和装置。 将氢气(或氢气和含硅烷气体)供给到设置有硅溅射靶(例如,靶30)的真空室(1)中,或者将氢气和含硅烷的气体供应到 在不将硅溅射靶设置在其中的腔室(1)中,向气体施加高频功率,从而产生等离子体,使得发射强度Si(((nm)/ Hbeta) 288nm波长的硅原子和等离子体发射波长为484nm的氢原子的发光强度Hbeta为10.0以下,优选为3.0以下,0.5以下,硅点(SiD ),在500度的低温下直接在基板(S)上形成粒径为20nm以下或10nm以下的粒径。 在等离子体中(如果存在硅溅射靶,则具有化学溅射)。

    • A ring-like rib 19 is erected on an inner circumferential edge of an insertion hole 11, which is opened in the scroll casing 1 so that the fan f is inserted therethrough, while a side wall 18 facing the ring-like rib 19 is provided in the bracket 15 blocking the insertion hole 11. A helical groove portion 20 and a protruding portion 21 are formed in one of an outer surface of the side wall 18 and an inner surface of the ring-like rib 19 and in the other thereof, respectively. The bracket 15 is caught in the scroll casing 1 by turning the bracket 15 in a direction opposite to a direction of rotation of said fan f. Further, during the engagement therebetween, a cooling duct 4 is formed.
    • 环形肋19竖立在插入孔11的内周缘上,该插入孔11在涡旋壳体1中打开,从而风扇f插入其中,而面向环状肋19的侧壁18 在支架15中,阻挡插入孔11.在侧壁18的外表面和环状肋19的内表面之一中形成螺旋槽部20和突出部21, 分别。 托架15通过沿与所述风扇f的旋转方向相反的方向转动支架15而卡在涡旋壳体1中。 此外,在其间的接合期间,形成冷却管道4。
