    • Improved sputtering chambers (100,200) for sputtering thin coatings onto substrates. One sputtering chamber includes spall shields (212) which are disposed inwardly and upwardly toward the chamber interior and toward the sputtering targets, and which can aid in the retention of overcoated sputtering material which may otherwise fall onto substrates to be coated. Another sputtering chamber includes targets (102, 103) having magnets (104, 105) which are turned inwardly relative to vertical and toward each other. The inward rotation of the magnets can serve to deposit more material toward the open bottom center of the chamber, and less toward the side walls of the chamber. Yet another sputtering chamber (300) includes a third target (314) disposed between and upward of the lower two targets (310, 312) so as to shield a portion of the sputtering chamber interior from material sputtered from the first and second targets . Some chambers have the three targets forming a triangle, for example, an isosceles or equilateral triangle, hi one chamber having such a triangular configuration of sputtering targets, the first and second targets form the base of an isosceles triangle and have their magnets oriented inwardly relative to vertical and towards each other. The sputtering chambers provided can either reduce the amount of overcoat sputtering material deposited onto the interior of the chamber and/or aid in retention of overcoat sputtering material which would otherwise fall onto substrates to be coated.
    • 改进的溅射室(100,200),用于将薄涂层溅射到基板上。 一个溅射室包括防护罩(212),它们向内并向上设置朝向室内部并且朝向溅射靶,并且其可以有助于保留另外可能落在待涂覆的基板上的外涂溅射材料。 另一个溅射室包括具有磁体(104,105)的靶(102,103),磁体(104,105)相对于垂直方向和彼此朝向内侧转动。 磁体的向内旋转可用于将更多的材料沉积到腔室的敞开的底部中心,并且朝向腔室的侧壁较少。 又一个溅射室(300)包括设置在下两个靶(310,312)之间和之上的第三靶(314),以便将溅射室内部的一部分与第一和第二靶溅射的材料进行屏蔽。 一些室具有形成三角形的三个目标,例如等腰或等边三角形。在具有这种溅射靶的三角形构造的一个室中,第一和第二靶构成等腰三角形的基部并使其磁体向内相对 相互垂直。 所提供的溅射室可以减少沉积在室内部的外涂层溅射材料的量和/或辅助保留外涂层溅射材料,否则这些溅射材料将落在待涂覆的基板上。
